Abstract
- O objetivo deste relato de caso foi correlacionar achados da histopatologia com a angiografia por fluoresceína (AF) e por indocianina verde (AIV) em um paciente com oftalmia simpática. Após dois meses de trauma perfurante no olho direito, o paciente apresentou baixa acuidade visual no olho esquerdo (OE). A AF do OE mostrou áreas de hipofluorescência homogênea na fase arterial e venosa, áreas de progressiva hiperfluorescência granular e vazamento do disco. A AIV mostrou áreas de hipofluorescência na fase inicial à tardia. A histopatologia foi realizada após evisceração do olho direito e demonstrou difuso edema da coriocapilar, inflamação da coróide, áreas focais de hiperplasia do epitélio pigmentar da retina, focos de células epitelióides entre a coróide e o epitélio pigmentar da retina, além da infiltração linfocitária das veias episclerais e descolamento de retina. A hiperfluorescência observada na AF foi correlacionada com o descolamento de retina e inflamação do nervo óptico. A hipofluorescência na AF e AIV correspondeu à presença de células inflamatórias (nódulos de Dalen-Fuchs) e edema coriocapilar difuso. This study correlates fluorescein angiography (FA) and indocyanine green angiography (ICGA) to histopathologic findings in a patient with sympathetic ophtalmia. A male with a perforated trauma in right eye presented after two months a decrease in visual acuity of the left eye. FA and ICGA were performed and the images were correlated with the histopathologic findings of the enucleated eye; FA showed background areas of homogeneous hypofluorescence in the arterial and venous phases, as well as areas of granular progressive hyperfluorescence and leakage from the optic disc. ICGA showed areas of hypofluorescence in the early and intermediate phases of the examination, which persisted until the late phase. During the early phase, there was also diffuse hypofluorescence caused by blockage that allowed observation of areas of partial choroidal circulation. The histopathology of the enucleated right eye showed diffuse choriocapillaris edema and inflammation of the choroids, focal areas of hyperplasia of the retinal pigment epithelium (RPE) as well as foci of epithelioid cells located between the choroid and the RPE. Furthermore, lymphocytic infiltration of the episcleral veins and retinal detachment were present. The hyperfluorescence observed on FA was correlated to retinal detachment and optic nerve inflammation. The hypofluorescence noted on FA and ICGA corresponded to the presence of blocking inflammatory cells (Dalen-Fuchs-like nodules) and to diffuse choriocapillaris edema.
