Estudio retrospectivo de tasa de éxito y factores asociados de dos técnicas de dacriocistorrinostomía láser, en un hospital de tercer nivel / Retrospective study of success rate and associated factors of two laser dacryocystorhinostomy techniques, in a third-level hospital

Objetivo Comparar la tasa de éxito de dos técnicas de dacriocistorrinostomía láser (DCRL). Materiales y métodos Se realizó un estudio retrospectivo de pacientes intervenidos por obstrucción adquirida de la vía lagrimal (OAVL) entre los años 2000 y 2021 en un hospital de tercer nivel, mediante DCRL con mitomicina intraoperatoria (DCRL + MMTC) y de DCRL asociada a ampliación de ostium con endoscopio y MMTC (DCRLend-amp + MMTC). Se analizaron hallazgos intraoperatorios, complicaciones y tasa éxito anatómico y funcional de las dos técnicas. El tiempo de seguimiento fue de un año. Resultados Incluimos 92 vías lagrimales con OAVL. 71,7% mujeres, 84,8% unilaterales y edad media de 62,77 ± 13,08 años. En 61 vías lagrimales se realizó DCRL + MMTC (66,3%) y en 31 (33,6%) DCRLend-amp + MMTC. La tasa de éxito anatómica/funcional al año de la DCRLend-amp + MMTC fue de 71%/64,5%; la DCRL + MMTC obtuvo una menor tasa de éxito, 65,6%/60,7% (p = 0,391). No existen diferencias a lo largo del seguimiento entre las tasas de éxito anatómicas ni funcionales de las dos técnicas, ni en las distintas visitas (p > 0,05). La tasa de hallazgos intraoperatorios fue de 1,63% en DCRL + MMTC y 32,26% en DCRLend-amp + MMTC. La tasa de complicaciones postoperatorias fue de 3,27% en DCRL+MMTC y de 3,23% en DCRLend-amp + MMTC. Conclusiones La DCRLend-amp + MMTC obtiene una tasa de éxito ligeramente más alta que la DCRL + MMTC. Debemos tener en cuenta el tiempo-coste quirúrgico aumentado de la DCRLend-amp + MMTC, curva de aprendizaje, y destreza del cirujano, sin un beneficio claro en la tasa de éxito (AU)

Background and objective To compare the success rate of two laser dacryocystorhinostomy (L-DCR) techniques. Materials and methods A retrospective study of patients who underwent surgery for acquired nasolacrimal duct obstruction (NLDO) between 2000 and 2021, carried out in a third level hospital, using L-DCR and modifications of this technique. Intraoperative findings, complications, and anatomical and functional success rate of the 2 techniques were analyzed. The follow-up time was 1 year. Result We included 92 lacrimal ducts with NLDO. 66 (71.7%) were women. 78 (84.8%) underwent unilateral surgery. The mean age was 62.77 ± 13.08 years. 61 (66.3%) underwent intraoperative laser dacryocystorhinostomy with MMTC (L-DCR + MMTC) and 31 (33.6%) L-DCR associated with endoscopic ostium enlargement (L-DCRend-amp). The one-year anatomical/functional success rate of the L-DCRend-amp + MMTC was 71%/64,5%. L-DCR + MMTC obtained a lower success rate, 65.6/60,7% (P = .391). There were no differences throughout the follow-up between the anatomical or functional success rates of the 2 techniques, nor between the different visits (P > .05). Intraoperative findings rate was 3.63% in L-DCR + MMTC, and 32.26% in L-DCRend-amp + MMTC. Postoperative complication rate was 3.27% in L-DCR + MMTC, and 3.23% in L-DCRend-amp + MMTC. Conclusions The L-DCRend-amp + MMTC gets a higher success rate than the L-DCR + MMTC. We must consider the surgical time-cost of the L-DCRend-amp + MMTC, as well as the learning curve of endoscopy techniques, and the skill of the surgeon, without a clear benefit in the success rate (AU)

Objetivo Identificar las características clínicas y epidemiológicas de los pacientes con parálisis facial periférica (PFP) en un hospital terciario. Método Es un estudio observacional retrospectivo de pacientes con PFP atendidos en un centro hospitalario de tercer nivel. Se recogieron datos demográficos, etiología, lateralidad, recurrencia, recuperación, clínica oftalmológica, severidad según la escala de House-Brackmann (HB), realización de pruebas electrofisiológicas, los servicios médicos que los atendieron, tratamiento médico y quirúrgico. Resultados Se incluyeron 283 pacientes con PFP, 135 (48%) eran varones y 148 (52%) eran mujeres (p=0,47). Todos con afectación unilateral. La media de edad fue de 54±20 años. La etiología principal fue idiopática en 215 (76%) pacientes. La mediana del tiempo de recuperación fue 7 semanas. La recuperación fue completa en 190 (67%) pacientes. Ciento setenta pacientes (84%) con PFP idiopática tuvieron recuperación completa, frente a 30 (16%) pacientes con PFP no idiopática (p<0,01). El 84% de los pacientes con parálisis grado II de la escala de HB se recuperaron completamente, mientras que con el grado VI de la escala de HB se recuperó solo el 17% (p=0,003). Doscientos veintenueve pacientes (81%) presentaron lagoftalmos. La mayor parte recibieron como tratamiento el cuidado de la superficie ocular 271 (96%) pacientes y de estos 249 (88%) pacientes recibieron corticoterapia oral. Trece pacientes (5%) requirieron cirugía oftalmológica. Conclusiones La PFP es una enfermedad que afecta a todos los rangos de edad, sin predilección por el sexo y unilateral. Su causa principal es idiopática. La recuperación es completa en la mayoría de los casos, siendo más favorable en afectaciones leves e idiopáticas. La mayoría solo requiere tratamiento médico (AU)

Dacriocistorrinostomía láser endocanalicular y sus modificaciones: revisión sistemática de técnicas y tasa de éxito / Endocanalicular Laser Dacryocystorhinostomy and its modifications: A systematic review of techniques and success rates

Objetivo El objetivo principal de este trabajo es revisar los artículos que hacen referencia a la técnica de la dacriocistorrinostomía láser (DCRL) para la obstrucción adquirida de la vía lagrimal (OACN), así como sus modificaciones, a través de una exhaustiva revisión bibliográfica. Material y método Se realizó una revisión sistemática de las publicaciones relacionadas con cirugía láser de la vía lagrimal desde el año 2000 hasta marzo de 2021 en las bases de datos MEDLINE, EMBASE y Cochrane Library. Los términos de búsqueda en idioma español e inglés fueron: «Endocanalicular laser», dacryocystorhinostomy or «primary DCR-L» or «laser» and «tear ducts». Resultados Tras someter los artículos a los criterios de inclusión y exclusión, obtuvimos 49 artículos: 21 estudios retrospectivos y 28 estudios prospectivos. El resultado bibliométrico obtenido garantiza, para la presente revisión, una recomendación de nivel C según la escala Scottish Intercollegiate Guidelines Network. Conclusiones Actualmente la DCRL clásica tiene tasas de éxito menores que las DCRL modificadas, por lo que sugerimos el uso de estas últimas. Preferimos la DCRL con MMC-IS o bien la DCRL con técnicas de endoscopia asociadas, sin poder decantarnos por ninguna opción en particular, puesto que las tasas de éxito son muy similares. Dejamos a criterio del cirujano la elección, dependiendo del manejo de las técnicas endonasales. Son necesarios más estudios, con mayor seguimiento, y mejor definidos para clarificar cuál es la mejor técnica DCRL (AU)

Objective The main objective of this work is to review the articles that refer to transcanalicular diode laser dacryocystorhinostomy (TCL-DCR) in acquired nasolacrimal duct obstruction (NLDO), as well as its modifications. Material and methods A systematic review of publications related to TCL-DCR of the lacrimal duct from 2000 to March 2021 was carried out in the MEDLINE, EMBASE and Cochrane Library databases. The search terms in Spanish and English were: «Endocanalicular laser», dacryocystorhinostomy or «primary DCR-L» or «laser» and «tear ducts». Results After subjecting the articles to the inclusion and exclusion criteria, we got 49 articles: 21 retrospective and 28 prospective studies. The bibliometric result obtained guaranteed, for this review, a level C recommendation according to the Scottish Intercollegiate Guidelines Network scale. Conclusions Currently, the classic TCL-DCR has lower success rates than its modifications, so we suggest using the latter. We prefer TCL-DCR with IS-MMC or TCDL associated with endoscopy techniques, without being able to opt for any option, since their success rates are very similar. We leave the choice to the discretion of the surgeon, depending on the management skills of endonasal techniques. More studies, with longer follow-up, and better defined criteria are necessary to clarify which is the best TCL-DCR technique (AU)

Recurrent bilateral asynchronous cellulitis: Report of two cases and a literature review.

Bilateral recurrent periorbital cellulitis is a very rare condition, with only five cases having been reported. Two cases are presented of recurrent bilateral asynchronous eyelid oedema in two paediatric patients. It was associated with respiratory infections, with no systemic disease. The patients had recurrent episodes (three times) since nine months old. They received oral and intravenous antibiotics, with a good response. There were no complications and no surgery was needed.

Celulitis recurrente bilateral asincrónica: a propósito de 2 casos y revisión de la bibliografía / Recurrent bilateral asynchronous cellulitis: Report of two cases and a literature review

La celulitis recurrente bilateral es una enfermedad muy poco frecuente, con tan solo 5 casos descritos en la literatura. Se describen 2 casos de edema palpebral recurrente bilateral asincrónico en 2 pacientes pediátricos asociados a infección respiratoria de vías altas, sin otra enfermedad asociada. Desde los 9 meses de edad padecieron recurrencias de la celulitis, hasta 3 veces, en ambos ojos. La antibioterapia oral e intravenosa resolvió cada proceso, sin desarrollar complicaciones ni necesidad de cirugía.

Eyelid nodules in idiopathic facial aseptic granuloma.

Idiopathic facial aseptic granuloma (IFAG) is a recently described and rare condition. It is considered a form of infantile granulomatous rosacea. IFAG with facial and eyelid nodules is very rare. A description is presented of three cases of IFAG eyelid nodules. They concern healthy children with no history of trauma. Biopsy examination revealed non-caseating inflammatory granulomas. Different medical treatments have been tried that seem to accelerate its healing, although its tendency is spontaneous resolution within several months. Painless recurrent eyelid nodules can be confused with chalazion. The diagnosis of IFAG should be considered in chronic eyelid nodules.

Acute dacryocystitis retention syndrome due to Epstein-Barr virus.

A 4 year-old boy with no previous history of eye or nasolacrimal disease was referred due to a painful mass on his left inner canthus, of three days onset, with no improvement in spite of oral antibiotics. On examination eyelid oedema with periocular hyperaemia was noted. Lacrimal sac palpation was painful and tonsillar exudation was reported. He was admitted and started on intravenous (iv) antibiotics. Four days later, lacrimal signs started to improve, but his general condition become worse. Head and neck Computed Tomography scan (CT scan) showed a left lacrimal sac enlargement, suggestive of acute dacryocystitis and swollen laterocervical lymph nodes. Epstein Barr Virus (EBV) serology and PCR testing were positive. The child responded well after eight days, and was discharged with oral antibiotics. Acute dacryocystic retention (ADR) associated with EBV was suspected. Six months later, the patient remained asymptomatic with no tearing or other lacrimal symptoms.

Síndrome de retención aguda lagrimal asociada a infección por virus de Epstein-Barr / Acute dacryocystitis retention syndrome due to Epstein-Barr virus

Varón de 4 años, sin antecedentes de obstrucción de vía lagrimal, que acude con una masa dolorosa en el canto interno del ojo izquierdo y febrícula de 3 días de evolución, sin mejoría con antibióticos orales por lo que se ingresa para estudio y tratamiento. En la exploración presenta edema palpebral con hiperemia periocular, dolor a la palpación del saco y exudado amigdalar. Se administran antibióticos por vía intravenosa. Tras 4 días de ingreso, el cuadro lagrimal mejora, empeorando el estado general con aparición de adenopatías cervicales. La tomografía computarizada órbito-cervical refleja un aumento del tamaño del saco lagrimal izquierdo compatible con dacriocistitis aguda y adenopatías cervicales. Serología y PCR positivas a virus de Epstein-Barr (VEB). Es dado de alta por resolución del cuadro a los 8 días con antibioterapia por vía oral. Se diagnostica de síndrome de retención aguda lagrimal asociado a VEB. A los 6 meses, continúa asintomático sin lagrimeo (AU)

Nódulos palpebrales en el granuloma aséptico facial idiopático / Eyelid nodules in idiopathic facial aseptic granuloma

El granuloma aséptico facial idiopático (GAFI) es una entidad recientemente descrita y poco frecuente. Se considera una forma de rosácea granulomatosa infantil. Es menos frecuente el GAFI con nódulos faciales y palpebrales asociados. Describimos 3casos GAFI que presentan esta asociación. Son niños sanos sin ningún antecedente traumático. El examen de la biopsia realizada en uno de los pacientes reveló granulomas inflamatorios no caseificantes. Se han ensayado distintos tratamientos médicos que parecen acelerar su curación, aunque su tendencia es la resolución espontánea en el plazo de varios meses. Los nódulos palpebrales indoloros de repetición se pueden confundir con el chalazión. Debemos pensar en GAFI ante nódulos palpebrales de larga evolución (AU)

Fístula orbitaria supratroclear secundaria a la realización de un bloqueo para anestesia en una cirugía de catarata / Orbital supratrochlear fistula secondary to anaesthetic block in cataract surgery

Presentamos un caso de una mujer con antecedente de bloqueo peribulbar derecho previo a cirugía de cataratas que a los pocos días presenta una fístula arteriovenosa intraorbitaria supratroclear derecha. Se resuelve sin secuelas a los 3 meses mediante la realización de masajes carotídeos homolaterales intermitentes. Es la primera vez que se describe una fístula arteriovenosa intraorbitaria de localización supratroclear. Solo se han descrito 8 casos de fístula arteriovenosa intraorbitaria postraumáticas y solo uno fue después de anestesia peribulbar

A case is described of a woman with history of right peribulbar nerve block prior to cataract surgery that, within a few days, presented with a trochlear intraorbital arteriovenous fistula. This was resolved without sequelae after three months by performing intermittent homolateral carotid massages. This is the first case of supratrochlear intraorbital arteriovenous fistula. There are only 8 cases reported of traumatic intraorbital arteriovenous fistula, and only one was with post-peribulbar anaesthesia

Sarcoidosis en cicatriz periocular como primer hallazgo de sarcoidosis sistémica: características clínico-radiológicas / Sarcoidosis in the periocular scar as the first finding of systemic sarcoidosis: Clinical-radiological characteristics

Se presenta un caso raro de una mujer caucásica de 29 años con un granuloma en una cicatriz antigua, en la región periocular derecha, como primer signo clínico de una sarcoidosis sistémica. Se procedió a una biopsia escisional de la lesión con diagnóstico anatomopatológico de inflamación crónica granulomatosa no necrosante, con características histológicas sugestivas de sarcoidosis de cicatriz. Al año, la lesión recidivó, por lo que se trató con esteroides depot intralesionales. Esta patología se produce con más frecuencia cuando existen cuerpos extraños y puede ser la primera señal de sarcoidosis sistémica

An unusual case is presented of a 29 year-old Caucasian woman with a granuloma in an old scar in the right periocular region as a first clinical sign of a systemic sarcoidosis. An excisional biopsy was performed, for which the histological diagnosis was a chronic non-necrotising granulomatous inflammation, suggestive of scar sarcoidosis. The lesion re-appeared one year after initial treatment, and was treated with intralesional depot steroids, showing adequate progression. This disease occurs more frequently in wound areas where there are foreign bodies and could be the first sign of systemic sarcoidosis

The effect of light and outdoor activity in natural lighting on the progression of myopia in children.

PURPOSE: To investigate potential risk factors for the progression of myopia. METHODS: Prospective study. Myopic progression was evaluated by cycloplegic autorefraction and axial length (AL) every 6 months in children 6 to 15 years old. Univariate analysis and multiple logistic regression were applied. RESULTS: Around 82 children with median age of 10.3±2.3 years. Myopia progressed by -0.816±0.6 D over 18 months. Increased myopic spherical equivalent refraction (SER) was correlated with increase in AL (P<0.001). Univariate analysis found SER to be significantly associated with: age, especially between 6 and 9.4 years old (P=0.001), parental myopia (P=0.028), and less time spent outdoors (P=0.009). There was a significantly greater increase in SER during months with the least daylight hours (P<0.001). CONCLUSION: Outdoor activities and daylight have a protective effect against increased AL and progression of myopia. Younger children with significant myopia should be monitored closely, especially those around 6 years old with myopic parents.

Adaptación de lentes de contacto en 133 ojos con astigmatismo irregular / Contact lens fitting in 133 eyes with irregular astigmatism

Objetivos: Estudiar la adaptación de lentes de contacto en 133 ojos con astigmatismos irregulares. Material y métodos: Se realizó un estudio retrospectivo en 133 ojos con astigmatismos irregulares. El criterio de inclusión fue tener un astigmatismo irregular imposible de corregir con gafas o con lentes de contacto de diseño estandard. Se efectuó una exploración oftalmológica completa, incluyendo topografía con Eye-Sys 2000. Las variables que se tuvieron en cuenta fueron: refracción, agudeza visual antes y después de la adaptación, etiología y tipo de lente de contacto. Resultados: De la muestra 50% fueron mujeres y 50% hombres, 52% de los ojos fueron derechos y 46% izquierdos y con afectación bilateral un 67%. El 78,2% (110 casos) de los ojos tratados correspondieron a queratoconos, 4 traumatismos corneales, 9 infecciones corneales y 6 astigmatismos idiopáticos. De las 133 lentes de contacto que se adaptaron 103 fueron lentes híbridas (Softperm(R)),, 20 sistemas piggy-back, 5 hidrofílicas gruesas (Queratosoft(R)), 4 hidrofílicas y 3 rígidas gas permeables. La agudeza visual (AV) previa media fue de 0.28 (DE 0,24) (rango 0,1-0,8). Después de la adaptación de la lente de contacto la agudeza visual fue de 0,81 (DE 0,23) (rango 0,1-1). Se encontraron diferencias significativas entre la AV pre/postratamiento con una mejoría visual de 0,53 (DE 0,28). Conclusiones: Sólo a través del manejo de multitud de lentes de contacto por un oftalmólogo especializado se puede llegar a un buen resultado visual-confort en ojo con astigmatismo irregular

Purpose: To study the adaptation of contact lens in a sample of 133 eyes with irregular astigmatism. Methods: A retrospective study was made in 133 eyes with irregular astigmatism. The selection criterion was to obtain a sample population with irregular astigmatism that was unlikely to be corrected with spectacles or conventional contact lens. A complete ophthalmologic exploration which included a topography with the Eye-Sys 2000 corneal topographer was made was made. The variables analyzed in the study were: refraction, visual acuity before and after the correction, cause of the astigmatism and contact lens used. Results: An equal number of women and men were enrolled in the study. The right eye was studied in 52% of cases, and the left eye in 46%. Both eyes were affected in 67% of the subjects. The reason for the astigmatism was keratoconus in 110 eyes (78.2%), and there were 4 corneal injuries, 9 ocular infections, and 6 idiopathic astigmatisms. Among the contact lens used in the study: in 103 eyes a hybrid lens (Softperm(R)), was adapted, in 20 eyes a piggyback system, in 5 eyes a thick hydrophilic lens (Queratosoft (R)),, in 4 eyes a hydrophilic contact lens and in 3 cases a rigid gas permeable contact lens. The average visual acuity before the adaptation was 0.28 (SD 0.24) (range 0.1-0.8). After the use of the lens the average visual acuity was 0.81 (SD 0.23) (range 0.1- 1). Statistically significant differences between the visual acuity before and after treatment were found, with an improvement of 0.53 (SD 0.28) obtained. Conclusion: Only with experience using a large variety of non-conventional contact lens can a specialist contact lens ophthalmologist achieve a good result
