PURPOSE: To report spectral-domain optical coherence tomography (OCT) and @entity3217 (FAF) features observed in a case of typical retinocytoma. METHODS: Case report. RESULTS: A 17-year-old @entity1 on routine ophthalmologic evaluation for @entity10 had an elevated translucent lesion with peripheral pigmentation and adjacent @entity5066 close to the disc in the nasal retinal quadrant of the left eye. The lesion was confirmed to be retinocytoma on fluorescein angiography. Optical coherence tomography revealed a hyperreflective layer akin to preserved nerve fiber layer overlying the lesion in most of the scans. Symmetrical hyporeflective spaces in the underlying choroid and at places sudden disruption of choroid was also observed in the area of @entity194 . Fundus autofluorescence revealed areas of hyperfluorescence, isofluorescence, and hypofluorescence in the different regions of the lesion. These features on FAF were consistent with posttreatment regressed retinoblastoma. Scleral hyperreflectivity on OCT as well as unmasked hyperfluorescence on FAF was observed in areas of @entity5066 . CONCLUSIONS: We report novel findings of superficial hyperreflective layer presumed to be preserved nerve fiber layer in a case of typical retinocytoma as well as FAF features consistent with regressed retinoblastoma.
