Traducción y validación del cuestionario Visual Function and Corneal Health Status (V-FUCHS) al idioma castellano / Translation and validation of the Visual Function and Corneal Health Status (V-FUCHS) questionnaire into Spanish language

Objetivo: Traducir y validar al castellano el cuestionario V-FUCHS en una población de pacientes que padecen distrofia endotelial de Fuchs (DEF).MétodosEl V-FUCHS consta de 15 preguntas, que valoran aspectos visuales de la calidad de vida en los pacientes con DEF, las cuales se pueden agrupar en 7 que valoran el factor «dificultad visual» y 8 que valoran el factor «deslumbramiento». Para la traducción y adaptación se siguieron las normas estandarizadas, destacando, una traducción, una retro-traducción y una aplicación en pacientes con DEF.ResultadosEn una primera fase se llegó al consenso de la traducción al castellano del V-FUCHS. Posteriormente, se incluyeron 25 pacientes para realizar la fase pre-test con el objetivo de valorar la aplicabilidad y la viabilidad del test. La puntuación de las mismas obtuvo un valor mínimo de −0,88 y un valor máximo de +2,44, según la escala probabilística de Rasch. El valor medio obtenido de las preguntas que conforman el factor dificultad visual fue de 0,61 (±0,71) y la media del factor deslumbramiento (Glare) fue de 0,41 (±0,51).ConclusiónLa validación del cuestionario V-FUCHS, tras su traducción y adaptación al castellano, demostró ser una herramienta útil para la valoración de la calidad visual de los pacientes con DEF. Los pacientes con un estado más avanzado de la enfermedad presentaron una mayor severidad en el resultado de la prueba. Asimismo, el factor deslumbramiento se correlaciona mejor con el aumento paquimétrico que con la agudeza visual del paciente. (AU)

Purpose: To translate and validate the V-FUCHS questionnaire into Spanish in a population of patients with Fuchs endothelial dystrophy (DEF).MethodsThe V-FUCHS consists of 15 short, easily understandable questions that assess visual aspects of quality of life in patients with DEF, which can be gathered into a group of seven that assess the “Visual Difficulty” factor and another group of eight that assess the “Glare Factor”. For the translation and cultural adaptation, the standardized norms for this process were followed, among other phases, a translation, a back-translation and an application in patients with DEF.ResultsIn the first phase, consensus was reached on the Spanish translation of the V-FUCHS. Subsequently, 25 patients were included to carry out the pre-test phase with the aim of assessing the applicability and feasibility of the test. The score obtained a minimum value of −0.88 and a maximum value of +2.44, according to the Rasch probabilistic scale. The mean value obtained from the Visual Difficulty factor was 0.61 (±0.71), while the mean for the Glare factor was 0.41 (±0.51).ConclusionThe validation of the V-FUCHS questionnaire, after its translation and adaptation into Spanish, proved to be a useful tool for assessing the visual quality of patients with DEF. Patients with a more advanced stage of the disease presented a greater severity in the test result. Likewise, the Glare factor (Glare) correlates better with the pachymetric increase than with the visual acuity of the patient. (AU)

Desprendimiento de retina tras la cirugía de cristalino transparente con lentes intraoculares EDOF y multifocales: una revisión narrativa / Retinal detachment after refractive lens exchange with EDOF and multifocal intraocular lenses: A narrative review

La cirugía de cristalino transparente (RLE) permite corregir las ametropías y la presbicia mediante el reemplazo del cristalino por una lente intraocular (LIO), ya sea monofocal, multifocal (MIOL) o de profundidad de foco extendida (EDOF). El desprendimiento de retina (DR) es uno de los eventos adversos más graves tras la RLE. El objetivo de este estudio fue revisar la evidencia y los resultados clínicos relacionados con el riesgo de DR después de la RLE. Se realizó una búsqueda utilizando PubMed y un procedimiento de bola de nieve para identificar estudios originales y series de casos. Según la bibliografía, los pacientes < 60 años con longitudes axiales > 23 mm tienen el mayor riesgo de DR. Solo nueve artículos reportaron la agudeza visual (AV) tras el DR en RLE, y solo 25% de los ojos mostraron una AV > 20/40. Teniendo en cuenta que la disminución de la AV tras el DR se puede dar con todos los tipos de LIO independientemente de su diseño óptico, la actitud más acertada al realizar una RLE sería una cuidadosa selección del paciente, evitando aquellos ojos con factores de riesgo para DR (AU)

Refractive lens exchange (RLE) allows to correct ametropias and presbyopia by replacing the crystalline lens with a monofocal, extended depth of focus or multifocal intraocular lens (IOL). Retinal detachment (RD) is one of the most serious adverse events after RLE. This study aimed to review the evidence related to the risk of RD after RLE and its clinical outcomes. A search using PubMed and a snowball search approach was conducted to identify articles and case reports. According to the literature, patients <60 years old with axial lengths >23 mm have the higher postoperative risk of RD. Only nine articles reported visual acuity (VA) after RD in RLE, and only 25% of eyes had a VA>20/40. Considering that the decrease in VA might be uniform for all types of IOLs after RD, surgeons should focus on preventing the RD by means of selecting the appropriate patient, rather than choosing on a particular IOL optical design (AU)

Revisión de la literatura sobre la evidencia disponible actualmente para el manejo de las queratitis infecciosas con PACK-CXL / Review of the literature on the currently available evidence for the management of infectious keratitis with PACK-CXL

Las queratitis infecciosas (QI) son una de las causas más comunes de ceguera a nivel mundial, especialmente en países en vías de desarrollo, y puede llegar a representar del 5,1 al 32,3% de todas las indicaciones de queratoplastia penetrante. Sin embargo, realizar una queratoplastia terapéutica «en caliente» está asociado con una mayor incidencia de recurrencia de la QI y rechazo del injerto. El tratamiento estándar incluye antimicrobianos (ATM) de amplio espectro y, una vez identificado el patógeno causante y el antibiograma, continuar con un tratamiento dirigido, según la sensibilidad del germen. La aparición de cepas multirresistentes a los ATM está aumentando progresivamente a un ritmo alarmante en los últimos tiempos. Asimismo, la diversidad de los microorganismos causantes (bacterias, hongos, parásitos, virus) dificulta en ocasiones la realización de un diagnóstico clínico correcto, retrasando el inicio de un tratamiento efectivo. Se estima que solo un 50% de los ojos tendrá un buen resultado visual si se retrasa la terapia. En definitiva, todos estos factores hacen que sea muy importante la identificación de alternativas al tratamiento ATM. Por las propiedades ATM del cromóforo fotoactivado (riboflavina) y la luz ultravioleta de longitud de onda 200-400nm, utilizada en múltiples aplicaciones médicas y no médicas para la desinfección, se ha propuesto el cromóforo fotoactivado para el cross-linking corneal en el tratamiento de las QI, como una herramienta adicional en el arsenal terapéutico de las QI. Debe diferenciarse del cross-linking empleado para el manejo del queratocono progresivo. El objetivo de esta revisión es actualizar la evidencia disponible sobre la eficacia y seguridad del cromóforo fotoactivado para el cross-linking en las QI (AU)

Infectious keratitis (IK) is one of the most common causes of monocular blindness worldwide, especially in developing countries, and may account for 5.1 to 32.3% of all indications for penetrating keratoplasty (PK). However, performing a therapeutic PK on a “hot eye” is associated with a higher incidence of IK recurrence and graft rejection. Standard treatment includes antimicrobials (ATM) and, once the causative pathogen has been identified, must be continued with targeted treatment, depending on antibiogram sensitivity. However, appearance of multiresistant strains to ATM is progressively increasing at an alarming rate. Besides that, the diversity of the causative microorganisms (bacteria, fungi, parasites, viruses) may hinder the clinical diagnosis and secondarily the proper treatment from the beginning. It is estimated that only 50% of eyes will have a good visual result if the correct therapy is delayed. All these factors make the identification of alternatives to ATM treatment of paramount importance. Due to the ATM properties of photoactivated chromophore (riboflavin) and ultraviolet light of wavelength 200-400nm, used in multiple medical and non-medical applications for disinfection, photoactivated chromophore for corneal cross-linking (CXL) of IK, as an addition to the therapeutic arsenal for the management of IK has been proposed. It must be differentiated from CXL used for the management of progressive keratoconus. The objective of this review is to update the available evidence on the efficacy and safety of photoactivated chromophore for corneal CXL in IKs (AU)

Review of the literature on the currently available evidence for the management of infectious keratitis with PACK-CXL.

Infectious keratitis (IK) is one of the most common causes of monocular blindness worldwide, especially in developing countries and may account for 5.1%-32.3% of all indications for penetrating keratoplasty (PK). However, performing a therapeutic PK on a "hot eye" is associated with a higher incidence of IK recurrence and graft rejection.

Due to the ATM properties of photoactivated chromophore (riboflavin, RB) and ultraviolet (UV) light of wavelength (λ) 200-400 nanometers (nm), used in multiple medical and non-medical applications for disinfection, photoactivated chromophore for corneal cross-linking (CXL) of IK (PACK-CXL), as an addition to the therapeutic arsenal for the management of IK has been proposed. It must be differentiated from CXL used for the management of progressive keratoconus (KC). The objective of this review is to update the available evidence on the efficacy and safety of PACK-CXL in IKs.

Study of the efficiency and workflow of femtosecond laser-assisted cataract surgery in a Spanish public hospital.

BACKGROUND: To assess the time-efficiency of a designated operating room (OR) workflow in the introduction of femtosecond laser-assisted cataract surgery (FLACS, LenSx, Alcon®). The study was carried out in a public hospital a with high-volume of procedures. METHODS: We performed this prospective, controlled, surgical intervention study in the ophthalmology department of a Spanish tertiary referral public hospital. A total of 167 eyes were enrolled, including 62 eyes undergoing conventional phacoemulsification surgery. In phase I, patients were assigned either to FLACS-I (n=63) or conventional phacoemulsification surgery (n=62). One surgeon operated the femtosecond laser, and another completed the procedure, while a third performed conventional phacoemulsification. In the second phase (FLACS-II), all the surgeries were FLACS (n=42). One surgeon performed the FLACS procedure, and two different surgeons completed the surgeries in separate ORs. Surgical and turnover times of all the patients were recorded. RESULTS: Preparation time was statistically significantly lower in FLACS-I and FLACS-II (P<0.001), whereas the duration of the cataract procedure per se was higher in FLACS-II compared to conventional phacoemulsification (P=0.03). Phacoemulsification energy was higher in FLACS-II compared to FLACS-I (P=0.01), whereas laser-related surgical time was lower (P=0.001). Surgical complications and total surgical time showed no statistically significant differences between any of the three groups. CONCLUSIONS: This study suggests a time-efficient and suitable workflow model for FLACS, considering the specific requirements and restrictions of a fully booked public hospital. Even so, we have shown that the FLACS procedure does not take longer than conventional phacoemulsification when following a detailed plan for OR workflow. In addition, our data reflect an improvement in FLACS surgical times with ongoing experience. TRIAL REGISTRATION: NCT03931629 (retrospectively registered).

Tamoxifen maculopathy: The importance of screening and long follow-up.

We report a case of a patient treated with tamoxifen 20mg daily as hormone therapy for breast cancer. On regular ophthalmological follow-up, tamoxifen maculopathy was detected on SD-OCT (Spectral Domain Optic Coherence Tomography, Carl Zeiss Meditec®), so the medication was discontinued. Despite discontinuation of the medication, the maculopathy progressed over time. We have been following our patient for seven years. Tamoxifen may produce a toxic maculopathy which may progress despite discontinuation of the medication. We consider our case interesting, given the lengthy follow-up of the patient with sequential SD-OCT images. To the best of our knowledge, our case represents the longest follow-up period for a patient with tamoxifen maculopathy. Moreover, we would like to stress the importance of screening in asymptomatic patients on this medication, in order to detect early pathological signs.

Extracción de cuerpo extraño orbitario con ayuda de electroimán ocular externo: instrumentos del pasado tienen cabida en el presente / Extraction of an intraorbital foreign body with the help of an ocular external electromagnet: Instruments of the past still have a place in the present

Los cuerpos extraños intraorbitarios (CEIO) son objetos que se sitúan en la órbita, normalmente metálicos, que pueden llegar a provocar serios daños estructurales y funcionales en el ojo y en el contenido orbitario. Presentamos el caso de un paciente con un CEIO metálico de localización anterior que se extrajo con la ayuda de un electroimán ocular externo tipo Livingston-Mansfield. A pesar de tratarse de un instrumento que podría considerarse «del pasado», sigue teniendo cabida en nuestro medio en determinadas circunstancias

Intraorbital Foreign Bodies (IOFB) are objects, usually of metallic nature, located outside the orbit cavity, and can potentially cause serious damage to ocular and orbital structures. The case is presented of a patient with an anterior metallic IOFB that was extracted with the aid of a Livingston-Mansfield ocular external electromagnet. Despite being an instrument «of the past», we believe that the electromagnet can still be useful in certain circumstances
