ABSTRACT

ABSTRACT Herein, we report two cases of vision loss after successful cataract surgery, associated with drusenoid retinal pigment epithelial detachment without features of choroidal neovascularization on optical coherence tomography along with angiographic examinations suggestive of choroidal neovascularization in which anatomical and functional improvements were achieved with intravitreal injections of anti-vascular endothelial growth factor.


RESUMO Relatamos dois casos de baixa visual após cirurgia bem sucedida de catarata, associada a descolamento drusenóide do epitélio pigmentar da retina (DPED) sem achados de neovascularização de coroide a tomografia de coerência óptica OCT (CNV silente ao OCT) e com exames angiográficos sugestivos de neovascularização da coroide (CNV), nos quais melhoras anatômicas e funcionais foram obtidas com aplicações intravítreas de anti-VEGF.

ABSTRACT

ABSTRACT This case report describes a 19-year-old Caucasian man presented with decreased visual acuity in the right eye for 3 months. Dilated funds exam revealed optic disk pit associated with serous macular detachment. Optical coherence tomography identified communication between the optic disk pit and the macular serous detachment, and optical coherence tomography angiography displayed a subfoveal area suggestive of subfoveal choroidal neovascularization. However, there was no evidence of leakage in the fluorescein angiogram and no evidence of choroidal neovascularization in optical coherence tomography in the area corresponding to the suspicious subfoveal choroidal neovascularization. The patient underwent 23-gauge pars plana vitrectomy in the right eye. Six weeks after surgery, multimodal imaging was repeated and there was near-complete resorption of the subretinal fluid. Optical coherence tomography angiography signal superimposed on optical coherence tomography B-scan also demonstrated normal choriocapillaris signal throughout the macula. In conclusion, optical coherence tomography angiography may produce artifacts in optic disk pit maculopathy that simulate choroidal neovascularization.


RESUMO O presente estudo relatou o caso de um homem caucasiano de 19 anos com diminuição da acuidade visual no olho direito há 3 meses. Na fundoscopia havia um pit de papila associado ao descolamento seroso macular. A tomografia de coerência óptica identificou uma comunicação entre o pit e o descolamento seroso e a angiografia por tomografia de coerência óptica demonstrou uma área subfoveal sugestiva de membrana neovascular sub-retiniana. No entanto, não houve evidência de vazamento na angiofluoresceínografia com contraste e nem de membrana neovascular sub-retiniana na tomografia de coerência óptica na área suspeita. O paciente foi submetido a vitrectomia pars plana 23-gauge no olho direito. Seis semanas após a cirurgia, os exames foram repetidos e houve reabsorção quase completa do líquido sub-retiniano. O sinal da angiografia por tomografia de coerência óptica sobreposto à tomografia de coerência óptica B-scan era normal na região da mácula. Em conclusão, a angiografia por tomografia de coerência óptica pode produzir artefatos em maculopatia secundária a pit de papila que simulam uma membrana neovascular sub-retiniana.

ABSTRACT

ABSTRACT We report enhanced depth imaging optical coherence tomography (EDI-OCT) features based on clinical and imaging data from two newly diagnosed cases of choroidal osteoma presenting with recent visual loss secondary to choroidal neovascular membranes. The features described in the two cases, compression of the choriocapillaris and disorganization of the medium and large vessel layers, are consistent with those of previous reports. We noticed a sponge-like pattern previously reported, but it was subtle. Both lesions had multiple intralesional layers and a typical intrinsic transparency with visibility of the sclerochoroidal junction.


RESUMO Relatamos as características na tomografia computadorizada óptica (EDI-OCT) de 2 pacientes recém diagnosticados com osteoma de coroide apresentando perda visual secundária à membranas neovasculares coroideanas. As características descritas em nossos 2 casos foram consistentes com trabalhos anteriores, exibindo a compressão da coriocapilar e desorganização das camadas médias e de grandes vasos. Notamos também o padrão em esponja anteriormente descrito, porém de forma discreta. Ambas as lesões tinham várias camadas intralesionais e uma transparência intrínseca típica com visibilidade da junção da esclero-coroideana.
