Hemorragia supracoroidea diferida después de queratoplastia endotelial automatizada con pelado de la membrana de Descemet (DSAEK) / Delayed suprachoroidal hemorrhage after descemet stripping automated endothelial keratoplasty (DSAEK)

Este estudio, una serie de 2casos y revisión de la literatura, pretende describir el segundo y tercer caso conocido de hemorragia supracoroidea diferida (DSCH) tras una queratoplastia endotelial automatizada con pelado de Descemet (DSAEK). La hemorragia supracoroidea consiste en la presencia de sangre en el espacio supracoroideo. La agudeza visual final no suele superar el 0,1 (escala decimal). Ambos casos presentan factores de riesgo: alta miopía, cirugía intraocular previa, hipertensión arterial o estar anticoagulados. El diagnóstico de hemorragia supracoroidea diferida se realizó en la primera visita de seguimiento: referían dolor intenso y agudo horas después de la cirugía. Fueron tratados con drenaje transescleral. La hemorragia supracoroidea diferida es una complicación rara pero devastadora y puede ocurrir después de un trasplante lamelar, como la queratoplastia endotelial automatizada con pelado de Descemet. Conocer esta complicación así como sus factores de riesgo permitirá un diagnóstico precoz, lo que mejorará el pronóstico de los pacientes (AU)

This study, a case series of 2patients and a literature review, aims to describe the second and third known cases of delayed suprachoroidal hemorrhage after Descemet stripping automated endothelial keratoplasty (DSAEK). The suprachoroidal hemorrhage is defined as the presence of blood in the suprachoroidal space; final visual acuity is rarely greater than 0.1 (decimal scale). Both cases presented had known risk factors: high myopia, previous ocular surgeries, arterial hypertension, and being under anticoagulant therapy. The diagnosis of delayed suprachoroidal hemorrhage was made at the 24-hour follow-up visit, as they recalled a sudden and tremendous acute pain hours after surgery. Both cases were drained through a scleral approach. Delayed suprachoroidal hemorrhage is a rare but devastating consequence that can occur after DSAEK. Awareness of the most critical risk factors allows for early identification, which is of paramount importance for the prognosis of these patients (AU)

Results of one decade of optical keratoplasty in pediatric patients.

BACKGROUND: Keratoplasty in the pediatric population has been considered a high-risk procedure. OBJECTIVE: To know the demographic data of patients younger than 18 years treated with optical keratoplasty, indications for surgery and its results. MATERIAL AND METHODS: A retrospective study was carried out at Conde de Valenciana Ophthalmology Institute, in which the medical records of patients younger than 18 years treated with optical keratoplasty from 2009 to 2019 were analyzed. RESULTS: A total of 53 eyes were included. The most common diagnosis and procedure were keratoconus and penetrating keratoplasty, respectively. Mean initial visual acuity was 2.05 ± 0.99 logMAR, and 0.82 ± 1.33 at last visit. Survival time was 130.34 months. Four failures were recorded. As for associated surgeries, corneal wound closure was recorded in seven eyes prior to transplant; during the keratoplasty procedure, anterior vitrectomy in two eyes, and after the transplant, Ahmed valve implantation and re-suture. A total of eight eyes had glaucoma, five of them diagnosed prior to transplantation. Regarding rejection, 15 eyes had an episode during follow-up, and mean time to transplant rejection was 10.8 months. CONCLUSION: Prolonged graft survival can be achieved with better knowledge and management of different associated factors.

ANTECEDENTES: La queratoplastia en población pediátrica ha sido considerada un procedimiento de alto riesgo. OBJETIVO: Conocer datos demográficos de pacientes menores de 18 años tratados con queratoplastia óptica, indicaciones de la cirugía y sus resultados. MATERIAL Y MÉTODOS: Se realizó un estudio retrospectivo en el Instituto de Oftalmología Conde de Valenciana, en el que se revisaron expedientes de pacientes menores de 18 años tratados con queratoplastia óptica de 2009 a 2019. RESULTADOS: Un total de 53 ojos fueron incluidos. El diagnóstico y el procedimiento más comunes fueron el queratocono y la queratoplastia penetrante. El promedio de agudeza visual inicial fue de 2.05 ± 0.99 logMAR y en la última visita, 0.82 ± 1.33. El tiempo de supervivencia del injerto fue de 130.34 meses. Se registraron cuatro fallas. En cuanto a las cirugías asociadas, antes del trasplante se registró cierre de herida corneal en siete ojos y durante la queratoplastia, vitrectomía anterior en dos ojos y después del trasplante, implante de válvula de Ahmed y resutura. Un total de ocho ojos tuvieron glaucoma, cinco con diagnóstico antes del trasplante. Respecto al rechazo, 15 ojos tuvieron un episodio durante el seguimiento y el tiempo promedio de rechazo al trasplante fue de 10.8 meses. CONCLUSIÓN: Se puede lograr una supervivencia prolongada del injerto con el mejor conocimiento y manejo de los diferentes factores asociados.

Resultados de los pacientes operados de queratoplastia terapéutica en la provincia de Matanzas

Introducción: la queratoplastia terapéutica se define como un procedimiento cuyo propósito es contribuir a erradicar o reducir la infección cuando la terapia médica máxima no es eficaz para lograr este fin. Objetivo: evaluar la evolución y resultados de los pacientes operados de queratoplastia terapéutica. Materiales y métodos: se realizó un estudio descriptivo transversal en un universo de 15 pacientes con diagnóstico de úlcera grave corneal. Dichos pacientes fueron operados de queratoplastia terapéutica en el Servicio de Córnea del Hospital Universitario Comandante Faustino Pérez Hernández, de la provincia de Matanzas, entre abril de 2017 y febrero de 2020, y dieron su consentimiento informado para participar en la investigación. Resultados: predominó el sexo masculino, con un 53,3 % y una media de edad de 58,8 años. Como factores predisponentes, prevaleció el antecedente de trauma en el 33,3 %, seguido del uso de lentes de contacto y la diabetes mellitus como enfermedad sistémica asociada. Las úlceras de etiología micótica predominaron en el 26,6 % de los casos; la perforación corneal y el descemetocele se presentaron en el 40 % y 26,6 % de los pacientes respectivamente. Durante el primer mes, las complicaciones postoperatorias más frecuentes fueron la recidiva de la sepsis y la necrosis del injerto. Por su parte, la opacidad y vascularización corneal fueron las secuelas más frecuentes. Conclusiones: la demora en iniciar el protocolo de tratamiento adecuado provoca cuadros severos de la enfermedad, realizando queratoplastia "en caliente" en córneas perforadas o con necrosis, que devienen complicaciones postoperatorias y secuelas no alentadoras para los pacientes.

Introduction: therapeutic keratoplasty is defined as a procedure whose purpose is to help eradicate or reduce the infection when maximum medical therapy is not efficacious to achieve this end. Objective: to evaluate the evolution and results of the patients operated on therapeutic keratoplasty. Materials and methods: a cross-sectional, descriptive study was carried out in a universe of 15 patients with a diagnosis of severe corneal ulcer. The patients underwent therapeutic keratoplasty surgeries in the Cornea Service of the Clinical Surgical University Hospital Comandante Faustino Perez Hernandez, in the province of Matanzas, between April 2017 and May 2020, and gave their informed consent to participate in the research. Results: male gender predominated, with 53.3% and a mean age of 58.8 years. As predisposing factors, trauma antecedent predominated in 33.3%, followed by the use of contact lenses and diabetes mellitus as associated systemic disease. Ulcers of mycotic etiology predominated in 26.6% of the cases; corneal perforation and descemetoceles occurred in 40% and 26.6% of the cases respectively. During the first month, the most frequent postsurgery complications were recidival sepsis and graft necrosis. On the other hand, corneal opacity and vascularization were the most frequent sequels. Conclusions: the delay in initiating the adequated protocol treatment causes severe symptoms of the disease that lead to "in hot" keratoplasty in perforated or necrosed corneas, causing postsurgery complications and non-encouraging sequels for patients.

Glaucoma y queratoplastia pediátrica / Glaucoma and Pediatric Keratoplasty

Introducción: La indicación de la queratoplastia en niños, el pronóstico y los factores de riesgo asociados a la supervivencia del injerto continúan en discusión hoy en día. Objetivo: Describir si existe relación entre factores pre- y posqueratoplastia con la presencia de glaucoma pediátrico. Métodos: Se realizó un estudio observacional, descriptivo longitudinal retrospectivo de serie de casos, en pacientes operados de queratoplastia en edad pediátrica. Las variables estudiadas fueron: edad, sexo, tiempo de seguimiento, ojo afectado, antecedentes patológicos oculares preoperatorios, causa de la queratoplastia, complicaciones posoperatorias, momento del fallo del injerto, líneas de visión ganadas, estado del injerto y realización de evisceración y uso de prótesis ocular. Resultados: Se estudiaron 24 ojos operados de queratoplastia en 22 pacientes menores de 18 años. La media de edad fue de 8,5 años y del tiempo de seguimiento, 8,1 años. El 100 por ciento de los pacientes con glaucoma tenían menos de 10 años de edad, el 80 por ciento de los pacientes con opacidad corneal congénita tuvo glaucoma. Los pacientes con glaucoma preoperatorio mostraron mayor probabilidad de descompensación de la tensión ocular tras la queratoplastia (83,3 por ciento), injerto opaco (50 por ciento); además, ambliopía (83,3 por ciento) y baja visión (66,6 por ciento) tras la queratoplastia. Conclusiones: La presencia de glaucoma preoperatorio influye negativamente en los resultados de la queratoplastia pediátrica. Futuros estudios prospectivos son necesarios para profundizar en los resultados de la queratoplastia en niños y sus factores de riesgo de fallo del injerto(AU)

Introduction: The indication for keratoplasty in children, prognosis and risk factors associated with graft survival remain under discussion today. Objective: To describe if there is a relationship between pre- and post-keratoplasty factors with the presence of pediatric glaucoma. Methods: An observational, descriptive, longitudinal, retrospective study of case series was performed in patients who underwent keratoplasty in pediatric age. The variables studied were: age, gender, follow-up time, affected eye, preoperative ocular pathologic history, cause of keratoplasty, postoperative complications, time of graft failure, lines of sight gained, graft status, evisceration and use of ocular prosthesis. Results: Twenty-four keratoplasty-operated eyes were studied in 22 patients under 18 years of age. The average age was 8.5 years and the average follow-up time was 8.1 years. One hundred percent of patients with glaucoma were less than 10 years of age; 80 percent of patients with congenital corneal opacity had glaucoma. Patients with preoperative glaucoma showed higher probability of ocular pressure decompensation after keratoplasty (83.3 percent), opaque graft (50 percent); in addition, amblyopia (83.3 percent) and low vision (66.6 percent) after keratoplasty. Conclusions: The presence of preoperative glaucoma negatively influences pediatric keratoplasty outcomes. Future prospective studies are needed to further investigate the outcomes of keratoplasty in children and its risk factors for graft failure(AU)

Opacidades corneales en niños / Corneal Opacities in Children

Si en el período temprano de la vida ocurre alguna condición que no permita una adecuada estimulación visual se produce la ambliopía por deprivación. Las afecciones corneales que se diagnostican en los niños pueden tener un origen congénito o adquirido, este último traumático o no. El conocimiento del diagnóstico de las afecciones que ocasiona opacidad corneal en niños es determinante para poder obtener todos los elementos necesarios que ayuden a identificar un diagnóstico lo más temprano y preciso posible y proveer una adecuada guía para escoger estrategias de tratamiento, por parte del equipo multidisciplinario involucrado. El objetivo fue abordar de manera actualizada las características en el diagnóstico y tratamiento de las opacidades corneales en edades pediátricas. Se realizó una búsqueda automatizada sobre el tema teniendo en cuenta las publicaciones de los últimos cinco años. Se utilizó la plataforma Infomed, específicamente la Biblioteca Virtual de Salud(AU)

If any medical condition that does not allow adequate visual stimulation manifests early in life, deprivation amblyopia follows. Corneal conditions diagnosed in children may have a congenital or acquired origin, the latter being traumatic or not. Knowledge of the diagnosis of conditions that cause corneal opacity in children is crucial to obtain all the necessary elements to help identify the earliest and most accurate diagnosis possible and to provide an adequate guide to choose treatment strategies by the multidisciplinary team involved. The objective was to address in an updated way the characteristics in the diagnosis and treatment of corneal opacities in pediatric ages. An automated search on the subject was carried out taking into account the publications of the last five years. The Infomed platform was used, specifically the Virtual Health Library(AU)

Evidence in the prevention of the recurrence of herpes simplex and herpes zoster keratitis after eye surgery.

OBJECTIVE: Herpetic keratitis, either due to herpes simplex keratitis (HSK) or herpes zoster ophthalmicus (HZO), can recur after eye surgery.º Prophylaxis is postulated as necessary to avoid it. The objective of this study was to review the scientific evidence on the preventive methods used in the perioperative period in patients previously affected by HSK/HZO. METHODS: An exhaustive search was carried out in the PubMed and Web of Science databases to identify relevant articles on prophylaxis and risk of recurrence of HSK/HZO in patients undergoing eye surgery up to 31 December 2019. RESULTS: There is strong evidence that oral prophylaxis should be recommended after penetrating keratoplasty in patients who have previously had HSK/HZO. For other types of surgery, the evidence is less compelling. However, a latent period of inactivity should be considered between disease and oral prophylaxis. CONCLUSIONS: Penetrating and lamellar keratoplasty, corneal crosslinking, cataract surgery, and photorefractive and phototherapeutic surgery cause an alteration of the subbasal nerve plexus of the cornea. Due to surgical trauma, as well as the modulation of the ocular immune response caused by steroids applied in the postoperative period, it is possible to induce the reactivation of HSK/HZO, which is common in some cases. Within this article, we discuss the available evidence for HSK/HZO prophylaxis in eye surgery. Further studies are necessary to define the real risk of HSK/HZO recurrence after ocular surgeries, particularly in cataract surgery, and to confirm the efficacy of perioperative prophylaxis with anti-HSK/HZO antivirals.

Evidencia en la prevención de la recurrencia de queratitis por herpes simple y herpes zóster tras cirugía ocular / Evidence in the prevention of the recurrence of herpes simplex and herpes zoster keratitis after eye surgery

Propósito: La queratitis herpética, ya sea por herpes simple (HSK) o por herpes zóster oftálmico (HZO) puede presentar recaídas tras la cirugía ocular. Se postula como necesaria una profilaxis para evitarla. El objetivo de este estudio es revisar la evidencia científica sobre los métodos preventivos empleados en el período perioperatorio en pacientes previamente afectados de HSK/HZO.MétodosSe ha realizado una búsqueda exhaustiva en las bases de datos PubMed y Web of Science para identificar artículos relevantes sobre profilaxis y riesgo de recurrencia de HSK/HZO en pacientes sometidos a cirugía ocular hasta el 31 de diciembre de 2019.ResultadosHay pruebas sólidas de que la profilaxis oral debe recomendarse tras una queratoplastia penetrante en pacientes que hayan sufrido previamente HSK/HZO. Para otros tipos de cirugías, la evidencia es menos convincente; sin embargo, debe considerarse un período latente de inactividad entre la enfermedad y la profilaxis oral.ConclusionesLa queratoplastia penetrante y lamelar, crosslinking corneal, cirugía de catarata y cirugía fotorrefractiva y fototerapéutica provocan una alteración del plexo nervioso sub-basal de la cornea. Debido al traumatismo quirúrgico, así como a la modulación de la respuesta inmunológica ocular causada por los esteroides aplicados en el postoperatorio, es posible inducir la reactivación de HSK/HZO, siendo en algunos casos común. Dentro del presente artículo discutimos la evidencia disponible para la profilaxis de HSK/HZO en cirugía ocular. Son necesarios estudios adicionales para definir el riesgo real de recurrencia de HSK/HZO después de cirugías oculares, particularmente en cirugía de catarata y para confirmar la eficacia de la profilaxis perioperatoria con antivíricos anti HSK/HZO (AU)

Caracterización de pacientes con úlcera grave de la córnea y queratoplastia terapéutica

RESUMEN Introducción: La queratoplastia ha sido la técnica más empleada para el tratamiento de las alteraciones corneales. Objetivo: Describir las características clínico-epidemiológicas de la queratoplastia terapéutica en pacientes con úlcera grave de la córnea. Método: Se realizó un estudio observacional descriptivo y transversal a 17 ojos de 16 pacientes operados de queratoplastia terapéutica que presentaron úlcera grave de la córnea, ingresados en el servicio de Oftalmología del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba en el periodo de enero de 2018 a diciembre de 2019. Se estudiaron las variables edad, sexo, procedencia, ocupación, factores predisponentes, tiempo de evolución previo al ingreso, tratamiento tópico previo y germen causal. En el análisis estadístico se utilizó la frecuencia absoluta y el porcentaje para las variables cualitativas y para las cuantitativas, la media y la desviación estándar. Resultados: Predominaron los pacientes del sexo masculino, jubilados con más de 60 años. Prevaleció el trauma ocular no quirúrgico como factor predisponente. Previo al ingreso se aplicó con mayor frecuencia el colirio antibiótico y el tiempo de evolución promedio fue de 12,2 días. El grupo de gérmenes más preponderante fue el de las bacterias. Conclusiones: El vínculo entre el germen causal y la aplicación de medicamentos tópicos previos de manera prolongada propicia que la enfermedad evolucione tórpidamente hacia formas graves de úlcera corneal. Lo que ofrece una respuesta deficiente y prolongada a los esquemas convencionales de tratamiento, que en ocasiones llevan a una queratoplastia terapéutica-tectónica.

ABSTRACT Introduction: Keratoplasty has been the most used technique for the treatment of corneal alterations. Objective: To describe the clinical-epidemiological characteristics of therapeutic keratoplasty in patients with severe corneal ulcer. Method: A descriptive and cross-sectional observational study was carried out on 17 eyes of 16 patients operated on for therapeutic keratoplasty who presented severe corneal ulcer, admitted to the Ophthalmology service of the Hospital "Dr. Juan Bruno Zayas Alfonso" in Santiago de Cuba, in the period from January 2018 to December 2019. The variables studied were: age, gender, origin, occupation, predisposing factors, time of evolution prior to admission, previous topical treatment and causal germ. In the statistical analysis, the absolute frequency and the percentage were used for the qualitative variables, and for the quantitative ones, the mean and the standard deviation. Results: Male patients predominated, retired with more than 60 years. Non-surgical ocular trauma prevailed as a predisposing factor. Prior to admission, antibiotic eye drops were applied more frequently, and the average evolution time was 12.2 days. The most preponderant group of germs was bacteria. Conclusions: The link between the causal germ and the application of previous topical medications in a prolonged manner favors the torpid evolution of the disease towards severe forms of corneal ulcer. This evolution offers a poor and prolonged response to conventional treatment schemes, which sometimes lead to a therapeutic-tectonic keratoplasty.

RESUMO Introdução: A ceratoplastia tem sido a técnica mais utilizada para o tratamento das alterações corneanas. Objetivo: Descrever as características clínico-epidemiológicas da ceratoplastia terapêutica em pacientes com úlcera de córnea grave. Método: Estudo observacional descritivo e transversal em 17 olhos de 16 pacientes operados de ceratoplastia terapêutica que apresentavam úlcera de córnea grave, internados no serviço de Oftalmologia do Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" em Santiago de Cuba no período de janeiro de 2018 a dezembro de 2019. Foram estudadas as variáveis idade, sexo, procedência, ocupação, fatores predisponentes, tempo de evolução antes da admissão, tratamento tópico prévio e germe causal. Na análise estatística, utilizou-se a frequência absoluta e o percentual para as variáveis qualitativas e para as quantitativas, a média e o desvio padrão. Resultados: Predominou pacientes do sexo masculino, aposentados com mais de 60 anos. O trauma ocular não cirúrgico prevaleceu como fator predisponente. Antes da internação, colírios antibióticos foram aplicados com maior frequência e o tempo médio de evolução foi de 12,2 dias. O grupo de germes mais preponderante foi o de bactérias. Conclusões: A ligação entre o germe causal e a aplicação de medicações tópicas prévias de forma prolongada favorece a evolução entorpecida da doença para formas graves de úlcera de córnea. O que oferece uma resposta pobre e prolongada aos esquemas de tratamento convencionais, que por vezes conduzem a uma queratoplastia tectónica terapêutico.

Long-term experience and Visual Acuity outcomes in Peters Anomaly cases.

PURPOSE: To report the results in a series of Peters Anomaly cases, and propose management and treatment approaches according to the alterations associated with each case. MATERIAL AND METHODS: A retrospective analysis was performed on the records of 27 patients (32 eyes) clinically diagnosed with Peters Anomaly. Each patient was subjected to different treatment modalities according to the type of Peters Anomaly, anywhere from medical follow-up clinics to a Penetrating Keratoplasty procedure (PKP). RESULTS: Of the 27 patients (32 eyes), 74% were male and 26% female, with 18.5% (5) being bilateral and 81.5% (22) unilateral. The mean number of years of follow-up was 10.2 years (Range: 3.5 to 18 years). The results of long-term VA correlate directly with the type of Peters Anomaly. For the total number of patients, the VA results were LogMAR 1.71 ±â€¯1.04. The results by groups were: Type I with only medical monitoring LogMAR 0.3 ±â€¯0, Type I with only Optical Iridectomy (OI) LogMAR 0.97 ±â€¯0.78, Type I with PKP LogMAR 1.22 ±â€¯0.97, Type II without a compromised posterior pole with PKP LogMAR 2.41 ±â€¯0.80, and Type II with a compromised posterior pole with PKP LogMAR 2.56 ±â€¯0.48. CONCLUSIONS: The result of VA and long-term corneal failure is directly related to the type of Peters Anomaly. Patients with Type I who only required medical follow-ups had the most favourable prognosis. Patients who underwent Peripheral Iridectomy followed and patients in which PKP was performed had an inferior prognosis.

Experiencia a largo plazo de pacientes con anomalía de Peters / Long-term experience and Visual Acuity outcomes in Peters Anomaly cases

ObjetivoComunicar los resultados de una serie de casos con anomalía de Peters, y proponer el manejo y sugerencias terapéuticas según alteraciones asociadas.Material y métodosSe analizaron las historias clínicas de 27 pacientes (32 ojos) con diagnóstico clínico de anomalía de Peters, los cuales fueron sometidos a diferentes tratamientos. Distintos parámetros y condiciones asociadas fueron evaluadas: presión intraocular (PIO), agudeza visual (AV), técnica quirúrgica y complicaciones postoperatorias.ResultadosDe los 27 pacientes (32 ojos), 74% sexo masculino y 26% femenino. El promedio de años de seguimiento fue de 10,2 años. La PIO preoperatoria fue de 23 ± 9,21 mmHg y al último control fue de 18,81 ± 7,45 mmHg. El resultado de AV a largo plazo se correlaciona directamente con el tipo de anomalía de Peters. Para el total los resultados de AV fueron LogMAR 1,71 ± 1,04 y por grupos: Tipo I sólo con seguimiento médico LogMAR 0,3 ± 0, Tipo I sólo con iridectomía periférica LogMAR 0,97 ± 0,78, Tipo I con queratoplastia penetrante (QPP) LogMAR 1,22 ± 0,97, Tipo II sin compromiso de polo posterior LogMAR 2,41 ± 0,80 y Tipo II con compromiso de polo posterior LogMAR 2,56 ± 0,48.ConclusionesEl resultado de AV y fracaso del injerto corneal a largo plazo se correlaciona directamente al tipo de anomalía de Peters, con mejor pronóstico la Tipo I en que se realizó sólo seguimiento médico, luego en los que se practicó iridectomía periférica, en los que se realizó QPP los que presentan peor pronóstico visual son con anomalía de Peters Tipo II con compromiso de polo posterior (p = 0.0087).

Comportamiento de los pacientes con distrofia corneal endotelial de Fuchs en la provincia Camagüey

Introducción: La distrofia corneal endotelial de Fuchs se trata de un trastorno degenerativo específico, bilateral y progresivo del endotelio corneal, es la más frecuente pero no siempre es diagnosticada en sus etapas iniciales en las consultas de oftalmología general. Objetivo: Describir el comportamiento clínico de pacientes con distrofia corneal endotelial de Fuchs en la provincia Camagüey. Métodos: Se realizó un estudio observacional, descriptivo, transversal en el Centro Oftalmológico del Hospital Universitario Manuel Ascunce Domenech en la provincia Camagüey desde noviembre 2019 hasta junio 2021. El universo de estudio estuvo constituido por todos los pacientes que asistieron durante el periodo de estudio y la muestra la conformaron 19 pacientes (38 ojos) quienes cumplieron con los criterios de inclusión y exclusión. Las variables estudiadas fueron edad, sexo, color de la piel, agudeza visual con corrección, asociación con glaucoma, paquimetría, biomicroscopía del segmento anterior, microscopía endotelial, microscopía confocal, estadio de la enfermedad y tipo de tratamiento aplicado. Resultados: Predominaron los pacientes entre 40 y 59 años de edad, el sexo femenino y color blanco de la piel. Sobresalió la visión útil, los valores de paquimetría altos y asociados al glaucoma. Se constató la presencia de guttas, edema corneal, bajo conteo celular con polimorfismo y polimegatismo. El estadio 2 estuvo en 47,4 % y el tratamiento médico se aplicó en el 97,4 %. Conclusiones: La distrofia aparece con más frecuencia después de los 40 años de edad, en sexo femenino y color blanco de piel. Predominó la visión útil, valores altos de paquimetrías y asociación con glaucoma. En la biomicroscopía del segmento anterior predominaron las guttas y el edema estromal y la microscopía endotelial y confocal se caracterizaron en su mayoría por el bajo conteo celular, las guttas, polimorfismo y polimegatismo. Prevaleció el estadio 2 y el tratamiento médico.

Introduction: Fuchs endothelial corneal dystrophy is a specific, bilateral and progressive degenerative disorder of the corneal endothelium, it is the most frequent but it is not always diagnosed in its initial stages in general ophthalmology consultations. Objective: To describe the clinical behavior of patients with Fuchs endothelial corneal dystrophy in Camagüey province. Methods: A cross-sectional descriptive observational study was carried out at the Ophthalmological Center of the Manuel Ascunce Domenech University Hospital in Camagüey in the period from November 2019 to June 2021. The study universe consisted of all the patients who attended during the study period and the sample was made up of 19 patients (38 eyes) who met the inclusion and exclusion criteria. The variables studied were age, sex, skin color, corrected visual acuity, association with glaucoma, pachymetry, anterior segment biomicroscopy, endothelial microscopy, confocal microscopy, disease stage, and type of treatment applied. Results: Patients between 40 and 59 years of age, female sex, and white skin color predominated. Useful vision stood out, high pachymetry values and associated with glaucoma, the presence of guttas, corneal edema, low cell count with polymorphism, and polymegatism was confirmed. Stage 2 was 47.4% and medical treatment was applied in 97.4%. Conclusions: Dystrophy appears more frequently after 40 years of age, in females and white skin persons. Useful vision, high pachymetry values, and association with glaucoma prevailed. In the biomicroscopy of the anterior segment, guttas and stromal edema predominated, and endothelial and confocal microscopy were mostly characterized by low cell count, guttas, polymorphism, and polymegatism. Stage 2 and medical treatment prevailed.

Aniridia and the ocular surface: Medical and surgical problems and solutions.

Congenital aniridia is a multisystemic genetic disease due to a mutation in PAX6 gene which severely affects the development and functionality of the human eyes. In patients affected by the mutation, aside from the absence or defects of iris tissue formation, abnormalities in position or opacities of the crystalline lens, macular hypoplasia, ocular surface disease is the main cause of visual loss and the deterioration of the quality of life of most patients. Limbal stem cell deficiency combined with tear film instability and secondary dry eye cause aniridic keratopathy which, in advanced stages, ends up in corneal opacification. In this paper, the actual knowledge about congenital aniridia keratopathy physiopathology and medical and surgical treatment options and their efficacy are discussed. Indications and results of topical treatments with artificial tears and blood-derivatives in its initial stages, and different surgical techniques as limbal stem cell transplantation, keratoplasty and keratoprostheses are reviewed. Finally, recent advances and results in regenerative medicine techniques with ex vivo stem cell cultivation or other types of cultivated cells are presented.

Prevalence and risk factors to develop ocular hypertension and glaucoma after penetrating keratoplasty.

OBJECTIVE: To determine the prevalence and factors associated with the development of ocular hypertension and glaucoma, in patients undergoing penetrating keratoplasty, in the Eye Clinic of the city of Bogotá. METHOD: A retrospective cross-sectional study was conducted, and 130 eyes of patients undergoing penetrating keratoplasty were analyzed at the Eye Clinic in Bogotá, between January 2015 and August 2018. Demographic and clinical data were obtained, and it was determined by bivariate analysis, the association factors and the prevalence of the pathology under study. RESULTS: Prevalence of ocular hypertension was 27.69% and glaucoma 10%. Average age 48.93 ± 18.63 years; higher frequency of presentation in men (61.5%). Statistically significant association factors were male sex (PR 2.59), presence of peripheral anterior synechiae (PR 1.83), history of trauma (PR 2.16), prior PK (PR 2.10) and graft failure (PR 2.04). Post-KP glaucoma only had statistically significant association with bullous keratopathy (PR 2.76). CONCLUSIONS: Ocular hypertension and glaucoma had a high prevalence after penetrating keratoplasty, and the association factors were similar to those reported in other international studies. Knowing these factors, allows focusing surveillance and treatment in these patients to avoid blindness due to damage of the optic nerve or corneal graft.

Prevalencia y factores de riesgo para desarrollar hipertensión ocular y glaucoma posterior a queratoplastia penetrante / Prevalence and risk factors to develop ocular hypertension and glaucoma after penetrating keratoplasty

Objetivo Determinar la prevalencia y los factores asociados con el desarrollo de la hipertensión ocular (HTO) y el glaucoma, en los pacientes sometidos a queratoplastia penetrante (QPP), en la Clínica de Ojos de la ciudad de Bogotá. Método Se realizó un estudio retrospectivo de corte transversal y se analizaron 130 ojos de pacientes sometidos a QPP, en la Clínica de Ojos de la ciudad de Bogotá, entre enero del 2015 y agosto del 2018. Se obtuvieron datos demográficos y clínicos y se determinó mediante el análisis bivariado los factores de asociación y la prevalencia de la patología a estudio. Resultados Prevalencia de HTO del 27,69% y glaucoma del 10%. Edad promedio 48,93 ± 18,63 años; frecuencia de presentación mayor en hombres (61,5%). Los factores de asociación estadísticamente significativos fueron el sexo masculino (PR 2,59), presencia de sinequias anteriores periféricas (PR 1,83), antecedente de trauma (PR 2,16), QPP previa (PR 2,10) y fracaso del injerto (PR 2,04).

Evaluation of the quality of life related to vision after penetrating keratoplasty. / Evaluación de la calidad de vida relacionada con la visión posterior a queratoplastia penetrante.

INTRODUCTION: Organ and tissue donation and transplantation represent the most important therapeutic advance of current times. The cornea is, by far, one of the most transplanted tissues worldwide due to the immune privilege of this tissue, as well as the advances in microsurgery, existence of cornea banks, preservation of corneas, and use of anti-rejection therapy. However, many patients with successful corneal transplants (with clear corneas) experience poor vision in the post-operative period due to irregular astigmatism, or other complications. OBJECTIVE: To evaluate the quality of life related to vision in patients undergoing penetrating keratoplasty. MATERIAL AND METHODS: A cross-analytical study including patients with a history of penetrating keratoplasty, over 18years of age, and at least 6months after surgery. The patients answered the Visual Function Questionnaire25 (VFQ-25) of visual function, a tool validated for use in Spanish, in which the higher the score, the better the quality of life. RESULTS: Thirty patients (20men and 10women), with a mean age of 61.2±18.7years, were included. The time of evolution after the transplant was 17.7±4months. The total quality of life score was 74.9±21.9, with significance in visual acuity (P<.001), and the presence of systemic comorbidities (P=.018). There was no significance between the transplant reason (P=.098) or ocular comorbidities (P=.119). CONCLUSION: The results suggest that visual acuity, as well as the presence of systemic comorbidities, has a significant impact on quality of life.

Early Penetrating Keratoplasty after interface fungal keratitis in Descemet Membrane Endothelial Keratoplasty. / Queratoplastia penetrante temprana después de queratitis fúngica de la interface en la queratoplastia endotelial de la membrana de Descemet.

In this case-report we describe the first reported case of early-onset fungal interface keratitis (IK) after Descemet Membrane Endothelial Keratoplasty (DMEK) successfully treated with penetrating keratoplasty (PK) during the active stage of infection. A patient with graft failure after Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) was operated on with DMEK. Donor rim culture and broth were positive for Candida albicans. Several interface infiltrates were confirmed and localized using anterior segment optical coherence tomography. Three days after diagnosis, observing clear signs of intraocular infection, the graft was removed with simultaneous washed-up of anterior chamber with fluconazole 1% followed by a PK and intrastromal corneal injections of fluconazole. A best-corrected visual acuity of 20/20 was achieved. This case highlights the importance of analysing every donor rim and broth, despite the patient doesn't show any symptoms or signs during the post-operative period. PK is a viable treatment option in early-onset interface keratitis.

Queratoplastia penetrante con fines ópticos. Presentación de cuatro casos / Penetrating keratoplasty with optical aims. Presentation of four cases

RESUMEN La queratoplastia penetrante ha sido el procedimiento empleado, de forma casi universal, para el tratamiento de las patologías corneales que afectan de forma irreversible a la visión. Se reportaron 4 casos clínicos de pacientes con afecciones corneales con compromiso visual severo, dado por visión de cuenta dedos y percepción luminosa. Luego de la evaluación completa en cada caso, se decidió realizar la queratoplastia penetrante con fines ópticos, con el objetivo de recuperar la transparencia de la córnea y la calidad visual. No existieron complicaciones transquirúrgicas y fueron seguidos según protocolo de evaluación postoperatoria de trasplante corneal. Los resultados y evaluación fueron satisfactorios, al año mantenían la transparencia del injerto y se logró mejoría considerable de la agudeza visual (AU).

ABSTRACT Penetrating keratoplasty has been a procedure used, almost universally, to treat corneal diseases affecting vision in an irreversible way. Four clinical cases are reported of patients with corneal affections severely compromising vision, given by short vision and luminous perception. After completely evaluating each case, the authors decided to perform the penetrant keratoplasty with optical aims, to recover cornea transparency and the vision quality. There were not transurgical complications and the patients were followed up according to the protocols of post-surgery evaluation of corneal graft. The results and evaluation were satisfactory; after a year, the transparency of the graft was maintained and visual acuity substantially improved (AU).

Pediatric penetrating keratoplasty and graft rejection: experience at the Hospital Infantil de México Federico Gómez.

Background: Penetrating keratoplasty (PK) is a challenging surgical ocular procedure indicated for some pediatric patients with vision-threatening corneal disease damage. Pediatric PK is reserved for cases with advanced pathology or dysfunction as rejection and failure rates greatly supersede the rates of adult PK. The objective was to identify factors associated with graft rejection and failure amongst Mexican children undergoing primary PK for different indications. Methods: A retrospective review of consecutive pediatric PK medical records was conducted between 2001 and 2015 at the Hospital Infantil de México Federico Gómez. Graft survival was calculated using the Kaplan-Meier survival method. Results: During the 15 years of study, 67 eyes of 57 patients underwent PK. The mean age at the time of surgery was 11 years. The mean follow-up duration was 44 months. Keratoconus was the most common indication for PK (61%) followed by herpetic keratitis (15%) and other corneal dystrophies (10%). Mean graft survival time was 45.6 months (95% confidence interval 31.8-58.4 months, standard deviation = 0.069), with a survival rate of 70% at 1 year. Univariate Cox proportional hazard showed that being < 9 years of age at the time of the surgery (p = 0.023) and corneal dystrophies (p = 0.04) were prognostic factors for corneal rejection. Five eyes of five patients developed graft failure. Conclusions: Pediatric PK patients commonly experience graft rejection, which need to be promptly diagnosed and treated to minimize permanent damage. The age at the time of surgery and congenital corneal opacities is factors associated with a higher risk of rejection and failure.

Introducción: La queratoplastia penetrante (QP) es un procedimiento quirúrgico indicado en algunos pacientes pediátricos con daño corneal con riesgo de fracaso que amenaza la visión. El objetivo del presente trabajo fue identificar los factores asociados a rechazo y fallo del injerto corneal en niños sometidos a QP. Métodos: Serie de casos de pacientes sometidos a QP en el Hospital Infantil de México Federico Gómez entre 2001 y 2015. La sobrevida del injerto fue calculada por el método de estimación de la función de supervivencia Kaplan­Meier. Resultados: Durante 15 años de estudio, 67 ojos de 57 pacientes fueron sometidos a QP. El promedio de edad de los pacientes al tiempo de la cirugía fue de 11 años. El seguimiento promedio fue de 44 meses. El queratocono fue la indicación más común de QP (61%), seguido de queratitis herpética (15%) y otras distrofias corneales (10%). El tiempo promedio de sobrevida fue 45.6% (intervalo de confianza [IC] 95%: 31.8-58.4 meses, desviación estándar [DS] = 0.069), con una tasa de sobrevida del 70% a 1 año. El riesgo proporcional de Cox univariado mostró que una edad < 9 años al momento de la cirugía (p = 0.023) y distrofias corneales (p = 0.04) son factores pronóstico para el rechazo corneal. Cinco ojos de cinco pacientes desarrollaron falla del injerto. Conclusiones: El rechazo del injerto en QP en pacientes pediátricos es común y puede ser resuelto satisfactoriamente en casi todos los casos con diagnóstico y tratamiento. La edad al momento de la cirugía y las opacidades corneales congénitas son factores asociados con el rechazo y fallo.
