Central Serous Chorioretinopathy in a Case of Regressed Familial Retinoblastoma

Purpose To present a case of central serous chorioretinopathy (CSC) in association with regressed familial retinoblastoma. Case report A 23-year-old man with regressed unilateral familial retinoblastoma in his left eye presented with decreased vision of the left eye since two months ago. The patient had undergone chemotherapy and cryotherapy for the treatment of retinoblastoma 20 years ago. In the left eye, funduscopy disclosed regressed mass of retinoblastoma, inferonasal to the optic disc, and focal subfoveal neurosensory detachment. Optical coherence tomography (OCT) and fluorescein angiography revealed CSC. As there was no sign of recurrence of retinoblastoma and retinal findings did not show late-onset chemotherapy-related retinopathy, the patient was diagnosed with CSC and followed up. After two months, visual acuity of the left eye improved, and repeated macular OCT revealed absorption of the subretinal fluid. Conclusion Subretinal fluid accumulation in a patient with regressed retinoblastoma is not always a sign of tumor recurrence or a treatment-related retinopathy.
