ABSTRACT

BACKGROUND: We undertook this study to evaluate the long-term effects of threshold retinopathy of prematurity (ROP) treatment using Argon laser under indirect ophthalmoscopy, as well as to analyze ocular diseases in those patients. METHODS: This is a descriptive, observational, longitudinal and prospective study carried out from March 1991 to February 2005, including patients with threshold retinopathy of prematurity for treatment using Argon laser under indirect ophthalmoscopy. Related ocular diseases were also reported. Descriptive statistics were applied. RESULTS: Follow-up was maintained for 14 years, 6.50 +/- 1.39 (CI 95%, p < 0.05), and 170 patients were studied. Weight was 1216.50 +/- 152.03 g (CI 95%, p < 0.05). Retinopathy was not present in 42% (72), in stage I-III, 46% (78), and threshold stage, 12% (20). Forty eyes were treated with Argon laser. After treatment, no progressive disease was found in 92.75%. We found high myopia in 20%, macular displacement 7.5%, strabismus 35%, retinal detachment (5%), optical nerve atrophy 5%, and ocular atrophy 5%. CONCLUSIONS: We were able to demonstrate that Argon laser treatment under indirect ophthalmoscopy has been effective in the control of threshold disease. The most important related ocular diseases were strabismus and myopia. Long-term monitoring has permitted us to initiate timely treatment for ocular diseases related to prematurity.

ABSTRACT

BACKGROUND: We undertook this study to determine the prevalence of premature retinopathy in a third level care hospital. METHODS: We carried out a descriptive, observational, longitudinal and prospective study from March 1991 to February 2004, including newborns with low birthweight of <1500 g and <35 weeks of gestation, evaluating the peripheral retina under pharmacological midryasis weekly during 4 weeks starting the 4th week of extrauterine life. The ROP international classification was used. RESULTS: Within our 12-year study, 2558 children were born, 62% were full term and 38% were premature. From 735 live premature births, 170 fulfilled inclusion criteria: 42% (72) did not present changes regarding retinopathy with a prevalence of 9.79, 46% (78) were in stages I-III with a prevalence of 10.61, and 12% (20) were in umbral stage with a prevalence of 2.72%. CONCLUSIONS: The prevalence of premature retinopathy in a third level hospital was 10.61% in stages I-III and 2.72% in umbral stage. This has allowed the evaluation of the peripheral retinal and the ability to plan treatment in the umbral stage to prevent future complications of blindness from disease progression in these cases.

ABSTRACT

Objetivo: Presentar la secuencia angiofluoresceinográfica retinal de pacientes con epiteliopatía pigmentaria retiniana difusa (EPRD). Material y métodos: Se analizaron cinco pacientes en quienes su estudio angio-fluoresceinográfic retinal mostraron las características propias de esa entidad. Resultados: Los casos que se presentan coinciden con las características clínicas y fluorangiográficas de la EPRD que surge como consecuencia de un desprendimiento seroso de la retina neurosensorial condicionando cambios en el epitelio pigmentado de la retina, dando la imagen de "escurrimiento" o "reguero" del material de contraste durante el estudio. Conclusiones: El diagnóstico de esta entidad se realiza con estudio angio-fluoresceinográfico retinal en el que la toma de imágenes de la periferia de la retina son importantes para delimitar el escurrimiento.

ABSTRACT

Objetivos: Determinar si dosis bajas de radiación alteran el curso natural de la neovascularización subfoveal en pacientes con degeneración macular relacionada con la edad (DMRE). Material y métodos: Se estudiaron pacientes con DMRE tipo húmeda determinándose edad, sexo, agudeza visual, transparencia del cristalino, campimetría computadorizada, extensión de la membrana por angiofloresceinografía y ultrasonido modo A y B. Se trataron con acelerador lineal de rayos X con dosis total de 1,500 cGy, fraccionada en 10 sesiones de 150 cGy, con haz de fotones de alta energía de 10 megaelectrón-volts. Seguimiento 18 meses. Resultados: Se trataron 34 pacientes con DMRE. La capacidad visual se mantuvo estable en 80 por ciento de los casos y 7 pacientes (20 por ciento) presentaron mejoría de una línea de visión, el campo visual se mantuvo estable en 82 por ciento, y el 18 por ciento mejoró; 6 pacientes mostraron un aumento en la opacidad del cristalino. El ultrasonido modo AB demostró reducción del grosor de la membrana neovascular subfoveal en un 34 por ciento (p<0,01). El área de extensión de la membrana también se redujo en 37.23 por ciento (p<0,05). Finalmente la respuesta global al tratamiento fue calificada como buena en el 55.8 por ciento y moderada para el 44.11 por ciento de los casos. Conclusión: Demostramos la utilidad de la radioterapia externa como un tratamiento alternativo para detener el crecimiento de la membrana neovascular subretiniana, manteniendo campo periférico, en pacientes con DMRE de tipo húmedo, cambiando la evolución natural de la enfermedad.

ABSTRACT

Se presenta el reporte de un caso de enfermedad de Bourneville con lesiones en piel, SNC y retina. Hacemos énfasis en la utilidad de la clasificación de Gómez para establecer el diagnóstico correcto de este tipo de facomatosis.
