Choroidal osteoma with choroidal excavation and associated neovascular membrane: An OCT-angiography study.

Abstract Clinical case A case is presented of a unilateral choroidal osteoma with choroidal excavation and associated neovascular membrane that was studied using OCT-angiography. The OCT and OCT-angiography revealed an area of choroidal excavation and an active neovascular membrane. Three doses of aflibercept were administered to the patient, which stabilized the neovascularisation. Discussion OCT-angiography was used to analyze the morphology of the superficial vascular network of the osteoma, as well as to monitor the evolution of the neovascular membrane.

Primary multifocal anaplastic large cell lymphoma with eyelid involvement: a case report

ABSTRACT Ocular adnexal involvement in CD30+ lymphoproliferative disorders is rare. We report the case of a 73-year-old woman with a relapsing primary cutaneous anaplastic large cell lymphoma on her eyelid. A systemic extension study excluded extracutaneous involvement. Systemic chemotherapy resulted in an optimal response, with complete regression of the cutaneous lesions. There has been no recurrence during the 2 years of follow-up. RESUMO O acometimento ocular adicional nos distúrbios linfoproliferativos CD30+ é raro. Relatamos o caso de uma mulher de 73 anos com linfoma de grandes células anaplásicas primárias recidivantes em sua pálpebra. A avaliação sistêmica excluiu envolvimento extr…

Osteoma de coroides con excavación coroidea y membrana neovascular asociada: estudio mediante angiografía-TCO

Resumen Caso clinico Presentamos un caso de osteoma de coroides unilateral con excavacion coroidea y membrana neovascular asociada estudiado mediante angiografia-TCO. En TCO y angiografia-TCO se objetivo excavacion coroidea y una membrana neovascular coroidea activa. Se administraron tres dosis de aflibercept estabilizando la neovascularizacion coroidea. Discusion La angiografia-TCO permitio el analisis morfologico de la red vascular superficial del osteoma asi como el control evolutivo de la membrana neovascular.

Bilateral maculopathy after exposure to a laser pointer: Optical coherence tomography angiography findings.

Abstract Case report A 36-year-old man went to the emergency department the day after exposure to a laser pointer. Funduscopy revealed dispersed macular pigment alterations, and optical coherence tomography showed a disruption of the retinal layers. The visual acuity was counting fingers in both eyes. Nine months later, optical coherence tomography angiography showed a rarefaction in the choriocapillaris vascular flow in the area of the laser injuries. Discussion The retinal layer mainly damaged by the laser injury was the retinal pigment epithelium. However, it is suggested that the laser injury could involve tissues beyond the retinal pigment epithelium, since a rarefaction of the chorioc…

Maculopatía bilateral por exposición a puntero láser: hallazgos en la angiografía mediante tomografía de coherencia óptica

Resumen Caso clinico Varon de 36 anos consulta tras exposicion bilateral a puntero laser el dia anterior. En funduscopia se evidenciaron alteraciones pigmentarias maculares dispersas y en tomografia de coherencia optica, desestructuracion de las capas retinianas. La agudeza visual fue de contaje de dedos en ambos ojos. Nueve meses despues se evidencio en la angiografia mediante tomografia de coherencia optica una alteracion del flujo vascular coriocapilar en la zona lesionada por el laser. Discusion El laser afecta principalmente al epitelio pigmentario retiniano. Sin embargo, con este caso ponemos de manifiesto la posible afectacion mas alla del epitelio pigmentario retiniano, apareciendo …

Retinal detachment with spontaneous dialysis of the ora serrata in a 13-year-old child with neurofibromatosis type 1: a case report.

A 13‑year‑old child diagnosed with neurofibromatosis type 1 who on a routine control presented with rhegmatogenous retinal detachment associated to dialysis of the ora serrata in the left eye (OS). There were no clinical signs or history of contuse ocular trauma. Neurofibromatosis produces alterations in fibroblasts of the cortex of the vitreous base. This results in deficient production of the collagen fibers that anchor the vitreous base to the pars plana and the peripheral neurosensory retina. Thus, suboptimal function of the fibroblasts explains spontaneous avulsion of the vitreous base. Such avulsion in turn is related to dialysis of the ora serrata.
