Epitelio pigmentario retiniano posterior a la aplicación del tratamiento cubano para la retinosis pigmentaria / Retinal pigmentary epitheliun observed after application of the Cuban treatment for retinitis pigmentosa

Objetivo: describir los posibles efectos sobre el epitelio pigmentario retiniano generados por la primera aplicación del tratamiento multiterapéutico cubano en pacientes con retinosis pigmentaria. Métodos: se realizó una investigación descriptiva longitudinal prospectiva, donde se seleccionaron 32 pacientes con retinosis pigmentaria, a quienes se les aplicó el tratamiento multiterapéutico cubano para esta enfermedad. Se utilizó un video angiógrafo de Heidelberg tipo 2 para realizar oftalmoscopia confocal por barrido láser infrarrojo, para adquirir y procesar imágenes de la capa media de vasos coroideos, antes del tratamiento, 15 días y un año después de realizar este. El análisis de los resultados se realizó mediante Statistica 6.0 y SPSS 15.0 sobre Windows. Resultados: un año después del tratamiento se observó que 6 ojos derechos y 5 ojos izquierdos mostraron diferencias no significativas con aumento de una milimicra al comparar los resultados en los tres momentos del estudio. Al mismo tiempo 4 ojos derechos y 4 izquierdos mostraron disminución no significativas de una milimicra. El resto de los 45 ojos estudiados no modificaron los resultados durante la investigación. Conclusión: la aplicación del tratamiento multiterapéutico cubano para tratar pacientes con retinosis pigmentaria es una alternativa que conserva el epitelio pigmentario retiniano(AU)

Objective: to describe the possible effects on the retinal pigmentary epithelium after the first application of the Cuban multitherapeutic treatment for patients with retinitis pigmentosa. Methods: a prospective, longitudinal and descriptive study of 32 patients with retinitis pigmentosa, who had received the Cuban multi-therapeutic treatment for this disease. There was used Heidelberg Retinal Angiograph- 2 to perform infrared laser scanning confocal ophthalmoscopy in order to take and process images from the medial layer of the choroidal vessels before, 15 days, and one year after treatment. The results were analyzed with Statistica 6.0 and SPSS 15.0 on Windows. Results: one year after the treatment, 6 right eyes and 5 left eyes showed insignificant differences with increase of one milimicra when making a comparison of the results of the three testing moments of the study. At the same time, 4 right eyes and 4 left eyes showed insignificant decrease of one milimicra. The rest of the 45 studied eyes did not change the results of the research study. Conclusion: the Cuban multitherapeutic treatment for retinitis pigmentosa is an alternative that preserves the retinal pigmentary epithelium(AU)

Microcephaly-chorioretinopathy syndrome, autosomal recessive form. A case report / Síndrome de microcefalia-coriorretinopatia, forma autossômica recessiva. Um relato de caso

CONTEXT: The autosomal recessive form of microcephaly-chorioretinopathy syndrome is a rare genetic condition that is considered to be an important differential diagnosis with congenital toxoplasmosis.CASE REPORT: Our patient was a seven-year-old white boy who was initially diagnosed with congenital toxoplasmosis. However, his serological tests for congenital infections, including toxoplasmosis, were negative. He was the first child of young, healthy and consanguineous parents (fourth-degree relatives). The parents had normal head circumferences and intelligence. The patient presented microcephaly and specific abnormalities of the retina, with multiple diffuse oval areas of pigmentation and patches of chorioretinal atrophy associated with diffuse pigmentation of the fundus. Ophthalmological evaluations on the parents were normal. A computed tomography scan of the child's head showed slight dilation of lateral ventricles and basal cisterns without evidence of calcifications. We did not find any lymphedema in his hands and feet. He had postnatal growth retardation, severe mental retardation and cerebral palsy.CONCLUSIONS: The finding of chorioretinal lesions in a child with microcephaly should raise suspicions of the autosomal recessive form of microcephaly-chorioretinopathy syndrome, especially in cases with an atypical pattern of eye fundus and consanguinity. A specific diagnosis is essential for an appropriate clinical evaluation and for genetic counseling for the patients and their families.

CONTEXTO: A forma autossômica recessiva da síndrome de microcefalia-coriorretinopatia é condição genética rara, considerada um importante diagnóstico diferencial com toxoplasmose congênita.RELATO DO CASO: O paciente era um menino branco de sete anos de idade, inicialmente diagnosticado com toxoplasmose congênita. No entanto, suas sorologias para infecções congênitas, incluindo a toxoplasmose, eram negativas. Ele foi o primeiro filho de pais jovens, hígidos e consanguíneos (parentes de quarto grau). Os pais apresentavam perímetro cefálico e inteligência normais. O paciente apresentava microcefalia e anormalidades específicas da retina com áreas ovais de pigmentação múltiplas e difusas, além de manchas de atrofia coriorretiniana associadas à pigmentação difusa do fundo de olho. A avaliação oftalmológica dos pais foi normal. A tomografia computadorizada de crânio da criança mostrou discreta dilatação dos ventrículos laterais e cisternas basais, sem evidência de calcificações. Nós não verificamos a presença de linfedema em suas mãos e pés. Ele possuía retardo do crescimento pós-natal, deficiência mental grave e paralisia cerebral.CONCLUSÃO: O achado de lesões coriorretinianas em uma criança com microcefalia deve aumentar a suspeita da forma autossômica recessiva da síndrome de microcefalia-coriorretinopatia, principalmente em casos com padrão atípico de fundo de olho e consanguinidade. O diagnóstico preciso é essencial para correta avaliação clínica e aconselhamento genético dos pacientes e suas famílias.

A Developmental Mechanism of Spontaneous Reattachment in Rhegmatogenous Retinal Detachment

This retrospective observational case series on eyes from three patients was done to elucidate the developmental mechanism of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD). The study eyes of each patients showed evidence of retinal break and diffuse retinal pigmentary change. Ultrasound biomicroscopic examination revealed vitreous fibers attached to the area around the retinal break. Posterior vitreous attachment was confirmed in each eye. A thin fibrovascular membrane incompletely sealing the retinal break was noted in one case. We suggest that the vitreous attachment around the retinal break and the sealing of the break with adjacent vitreous fibers seem to be involved in the developmental mechanism of SRRRD.
