Abstract
Atrophic tracts of the retinal pigment epithelium are angiographic images of the posteior pole, esp, inferior hemispheric retina. It is likely that serous detachment of the neuroepithelium constituting the central serous chorioretinopathy (CSC) of the posterior pole prolongs itself downwards, leaving a localized atrophy as a mark on the pigmented epithelium. In this study, they are presented in 8 cases (10 eyes) afected jointly by the CSC. All of the patients were male. The average age at the time of follow-up examination was 44.5 years. One of 10 eyes was noted to have clinically discernible, dependent peripheral retinal detachment. Retinal pigment epithelial atrophic tracts in this study were classified by 3 patterns in the FAG. One pattern presents as an irregular atrophic tract, which almost is located at the watershed zone near the temporal margin of the optic disc. Another pattern presents as the atrophic tract with a vertical line, which coursed vertically from the posterior pole into the inferior fundus. The other pattern composes of the two previous patterns. The atrophic tract of the RPE in the FAG showed hyperfluorescence. The lesions within the atrophic tracts of the RPE showed several depigmented spots and a pronounced window defect in the FAG. In the ICG angiography, the atrophic tracts of the tetinal pigment epithelium showed hypofluorescence distinctly during late phase of the ICG angiography.
