ABSTRACT

ABSTRACT Here, we describe the result of a Descemet's membrane endothelial keratoplasty for acute corneal hydrops in a 45-year-old female with keratoconus, who presented with severe visual loss in her OS. The patient's best-corrected visual acuity was 20/80 in the right eye and hand motion in the OS. Slit-lamp examination revealed an extensive tear of the Descemet's membrane and stromal corneal edema in the OS. We opted for Descemet membrane endothelial keratoplasty. Twelve months postoperatively, the patient had a best-corrected visual acuity of 20/50 in the OS.


RESUMO Trata-se de uma paciente do sexo feminino, de 45 anos, portadora de ceratocone, submetida a uma ceratoplastia endotelial com membrana Descemet após apresentar um quadro de perda de visão severa devido a uma hidrópsia corneana aguda no olho esquerdo. Inicialmente, a acuidade visual corrigida da paciente era de 20/80 no olho direito e de movimento de mãos no olho esquerdo. Após exame de biomicroscopia que detectou uma extensa rotura da membrana de Descemet e edema estromal, optamos por tratar esse caso com o ceratoplastia endotelial com membrana Descemet. Doze meses após o procedimento cirúrgico, percebeu-se uma melhora do edema corneano, não havia sinais de rejeição do botão óptico e a acuidade visual corrigida da paciente era de 20/50 no olho afetado.

ABSTRACT

RESUMEN Objetivo: Relacionar la severidad del edema corneal posfacoemulsificación en pacientes con córnea guttata, sin riesgo o bajo riesgo de edema posquirúrgico según densidad celular, con la dureza del cristalino y los parámetros facodinámicos. Métodos: Se realizó un estudio descriptivo, prospectivo, de 42 pacientes con córnea guttata, sin riesgo o bajo riesgo de edema posquirúrgico según densidad celular, sometidos a facoemulsificación por el mismo cirujano en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer", desde abril del año 2016 a abril de 2017. Se relacionó la severidad del edema corneal con la dureza del cristalino y los parámetros facodinámicos. Resultados: Predominaron los pacientes con 70 años o más (52,4 por ciento) y el sexo femenino (64,3 por ciento). A las 24 horas de operados, el edema corneal estuvo ausente en el 54,8 por ciento y se presentó leve (26,2 por ciento) o mínimo (19,0 por ciento). A los 7 días, el 71,4 por ciento tenía la córnea transparente. Fue más frecuente en la periferia y en la zona paracentral temporal (36,8 por ciento). Aquellos con dureza de cristalino NO2 NC2 no presentaron edema corneal. A los 7 días solo el 11,9 por ciento mantenía edema leve, asociado a cristalinos NO4 NC4 o superior. El edema corneal se presentó asociado al grupo en el que se usó un poder de ultrasonido entre 10 y 20 (36,0 por ciento). Conclusiones: La mayoría de los pacientes con córnea guttata, considerados sin riesgo o bajo riesgo de edema posquirúrgico según la densidad celular, no presentan edema posfacoemulsificación(AU)


ABSTRACT Objective: Determine the relationship between the severity of corneal edema in cornea guttata patients undergoing phacoemulsification considered to be at no risk or low risk for postsurgical edema in terms of cell density, and crystalline lens hardness and phacodynamic parameters. Methods: A descriptive prospective study was conducted of 42 cornea guttata patients considered to be at no risk or low risk for postsurgical edema in terms of cell density, who underwent phacoemulsification performed by the same surgeon at Ramón Pando Ferrer Cuban Institute of Ophthalmology from April 2016 to April 2017. Corneal edema severity was related to crystalline lens hardness and phacodynamic parameters. Results: A predominance was found of patients aged 70 years and over (52.4 percent) and the female sex (64.3 percent). Twenty-four hours after surgery corneal edema was not observed in 54.8 percent and where it was present it was either mild (26.2 percent) or minimum (19.0 percent). At 7 days 71.4 percent of the patients had a transparent cornea. It was more common on the periphery and in the temporal paracentral area (36.8 percent). Patients with NO2 NC2 crystalline lens hardness did not have corneal edema. At 7 days only 11.9 percent had mild edema associated to NO4 NC4 or higher crystalline lenses. Corneal edema was associated to the group in which an ultrasound power level between 10 and 20 (36.0 percent) was used. Conclusions: Most cornea guttata patients considered to be at no risk or low risk for postsurgical edema in terms of cell density do not develop postphacoemulsification edema(AU)

ABSTRACT

OBJECTIVES: To describe the indications for and visual outcomes of intrastromal corneal ring segment implantation. METHODS: A large retrospective case-series chart-review study was conducted using Sorocaba Ophthalmological Hospital medical records. This study included 1222 eyes (1196 patients) that were surgically treated between November 2009 and December 2012. The following preoperative data were collected: age, gender, type of medical care and funding source, surgical technique, best-corrected visual acuity, manifest sphere and cylinder refractive error, maximum and minimum central keratometry, and pachymetry measurements of the cornea at the thinnest point and at the ring channel. The postoperative best-corrected visual acuity and patient satisfaction were also determined. The cases were classified into six groups: four keratoconus groups (severe, advanced, moderate and mild), a pellucid marginal degeneration group and a post-graft irregular astigmatism group. This study was approved by the Brazilian Registry of Clinical Trials (UTN number 1111-1182-6181, TRIAL RBR-6S72RF). RESULTS: The age (mean±standard deviation) of the patients was 31.0±10.0 years. The most prevalent pathology was keratoconus (1147 eyes, 93.8%). A correlation was found between ectasia severity and medical assistance (p<0.001), and the most serious cases was treated by the Brazilian public health system. No complications were found in a total of 1155 surgeries, and after surgery, 959 patients were satisfied. Among the 164 dissatisfied patients, the majority failed to show improved best-corrected visual acuity. CONCLUSION: Patients in the public health system underwent surgical intervention for keratoconus later than those with private sources of funding. In the vast majority of operated cases, the patients reported improvements in vision.

ABSTRACT

A 40-year-old lady presented with severe endothelial cell loss in both eyes 14 years after angle-supported phakic intraocular lens (AS PIOL) implantation. The left eye had severe corneal edema with bullous keratopathy. The right eye had markedly reduced endothelial cell count (655 cells/mm2) although the cornea was clear. She underwent simultaneous bilensectomy (AS PIOL explantation and phacoemulsification) and Descemet's stripping and endothelial keratoplasty (DSEK) in the left eye. Explanted AS PIOL was identified as ZSAL-4 (Morcher, Stuttgart, Germany) model. Corneal edema cleared completely in 2 months with a best corrected visual acuity (-2.25 D sph) of 20/60. No intervention was done in the right eye. The present case illustrates that AS PIOL-induced endothelial decompensation can be effectively managed by simultaneous bilensectomy and endothelial keratoplasty.

ABSTRACT

El objetivo de este estudio fue determinar la evolución del glaucoma congénito primario en niños menores de 3 años atendidos en el Centro Nacional de Oftalmología “Dr. Emilio Álvarez Montalbán”, en el período de enero 2004 a diciembre 2008. El diseño del estudio fué descriptivo de corte transversal. La muestra la conformaron 20 pacientes, constituyendo 57.1% del universo, para un total de 24 ojos. El tipo de muestra fue no probabilística por conveniencia. Los resultados más importantes fueron que el 75% de los niños eran menores de 1 año, encontrándose en el grupo de 4-6 meses un 35%. El sexo masculino constituyó el 70%. Más de la mitad de los pacientes tenían procedencia fuera de Managua. El 80% de los pacientes tenían afectación unilateral. El lagrimeo constituyó el síntoma principal en más de la mitad de los pacientes, la excavación papilar en más del 50% de los ojos era mayor de 0.7, el diámetro corneal promedio fué de 13.6mm, la tonometría inicial promedio fué de 2.3/ 5.5 grs. y la tonometría final promedio fué de 6.5/5.5 grs., cerca de la mitad de los pacientes usaron tratamiento antiglaucomatoso en el prequirúrgico y el 70.8% de los pacientes tenían defecto refractivo miópico. En más del 90% de los ojos se realizó trabeculectomía con un antimetabolito.Se concluyó que la cirugía que se realizó en el 79.2% de los ojos de los pacientes fué trabeculectomía con 5 fluorouracilo, con lo cual se obtuvo un control de la PIO en el 62.5% ojos, reducción del edema corneal en 37.5% y la excavación papilar en el 12.5%.No hubo cambios en el diámetro corneal.Se recomendó elaborar un protocolo de manejo del glaucoma congénito y gestionar el equipo e instrumental necesario para la realización de goniotomía y trabeculotomía que son las cirugías de primera elección en el glaucoma congénito...

ABSTRACT

Introducción: La queratectomía con cauterización de la membrana de Bowman y el injerto de membrana amniótica son algunos de los tratamientos paliativos en pacientes con queratopatía bullosa dolorosa sin criterio de trasplante corneal. Describir los resultados de cada una de estas técnicas fue nuestro objetivo fundamental en este estudio. Métodos: Se realizó un estudio descriptivo con 34 pacientes con queratopatía bullosa dolorosa poscirugía de catarata. Se distribuyeron en dos grupos: queratectomía con cauterización de la membrana de Bowman y queratectomía con injerto de membrana amniótica con seguimiento por seis meses. Resultados: A los seis meses se mantenían sin bulas 64,7 y 41,2 por ciento de los casos con cauterización de la membrana de Bowman e injerto de membrana amniótica respectivamente. El incremento de la vascularización corneal fue mínimo para ambas técnicas quirúrgicas. Se logró el alivio de los síntomas en la primera semana de la cirugía para 82,4 por ciento en la cauterización de la membrana de Bowman y 94,1 por ciento en el injerto de membrana amniótica. A los seis meses de la cirugía se mantenían asintomáticos 88,2 y 70,6 por ciento de los casos con cauterización de la membrana de Bowman e injerto de membrana amniótica, respectivamente. La epitelización corneal se produjo antes de los 14 días en el 100 por ciento de los pacientes tratados con injerto de membrana amniótica y en el 94,1 por ciento de los pacientes con cauterización de la membrana de Bowman. Conclusiones: Ambas técnicas quirúrgicas fueron eficaces en el tratamiento a corto plazo de la queratopatía bullosa dolorosa poscirugía de catarata.


Introduction: Keratectomy with cauterization of Bowman´s membrane and the amniotic membrane graft are some of the palliative therapies to be applied in patients with painful bullous keratopathy without any criterion of corneal transplant. To describe the results of each technique was our fundamental objective in this study. Methods: A descriptive study of 34 patients with painful bullous keratopathy after cataract surgery was carried out. They were divided into two groups: one undergoing keratectomy with cauterization of Bowman´s membrane and the other amniotic membrane graft followed-up for six months. Results: After six months, 64.7 percent of cases with cauterization of Bowman´s membrane and 41.2 percent of those with amniotic membrane graft had no blebs. Increase of corneal vascularization as minimal for both techniques. The symptom relief in the first week of surgery was observed in 82.4 percent and 94.1 percent of cases respectively. After six months, the patients kept asymptomatic in 88.2 percent of cases with cauterized Bowman´s membrane and 70.6 percent of amniotic membrane grafts. Corneal epithelization occurred before 14 days of surgery in 100 percent of patients treated with graft and in 94.1 percent of cauterized cases. Conclusions: Both surgical techniques are effective in short-term treatment of painful bullous keratopathy after a cataract surgery.

ABSTRACT

PURPOSE: To report two cases of femtosecond laser-assisted small incision deep lamellar endothelial keratoplasty (DLEK) for patients with corneal endothelial decompensation by Fuchs dystrophy and glaucoma METHODS: Femtosecond laser (IntraLase(R); IntraLase Corp., Irvine, CA) with 15 kHz of repetition rate, was used for a 9.5 mm diameter by 400 micrometer thickness donor corneal lamellar dissection. RESULTS: In Case 1, the graft was clear and compact without interface haze, Orbscan showed smooth and regular corneal surface, specular microscopy was unremarkable without sign of corneal endothelial damage, and Optical coherence tomography showed uniform graft well attached to recipient stroma with minimal interface reflection at 2 months postoperation. In Case 2, the graft was clear and compact with minimal interface haze at 1 month postoperation. Femtosecond laser-assisted small incision DLEK was safe and technically feasible in our cases; however, further evaluation is required to determine long-term effects.

ABSTRACT

La descompensación corneal postfacoéresis puede ir desde una simple pseudofaquia con descompensación endotelial hasta una afaquia con un trastorno global del segmento anterior con compromiso de cápsula, vítreo, iris, ángulo y córnea. Su reparación, por lo tanto, irá desde una simple queratoplastía penetrante hasta una restauración anatomofuncional lo más completa posible, incluso con la fijación de un LIO a la esclera. Este trabajo presenta 20 casos de reformación de segmento anterior postfacoéresis, en su mayoría con LIO fijado a esclera. Se analiza sus resultados, su manejo quirúrgico y su prevención. Su seguimiento de 6 a 30 meses y los resultados, tanto en su AV (mejor en el 75% de los casos) como en las complicaciones, permiten plantear a esta cirugía como una real alternativa terapéutica en este tipo de casos
