Central Serous Chorioretinopathy in Nanophthalmos

Abstract

Purpose: To report a case of bilateral central serous chorioretinopathy (CSC) occurring in a patient with nanophthalmos with long term follow up Methods: Case Report Results: A 37-year old male presented with diminution of vision in right eye (RE) since 3 days. On examination his best corrected visual acuity (BVCA) was 5/60 in RE and 6/18 in LE His refractive correction was +8.00D sphere. Anterior segment examination revealed small eyes with narrow palpebral fissures, shallow anterior chamber and clear lens. His axial length was 15.94mm in the RE and 15.89mm in the LE respectively. Fundus examination revealed a crowded disc with tortuous vessels in both eyes and the presence of subretinal fluid (SRF) in the macular area in the RE. Multimodal imaging included enhanced depth imaging spectral domain optical coherence tomography (EDI SD-OCT) and fundus fluorescein angiography (FFA) which revealed features suggestive of thick choroids BE, ink-blot leak on FFA suggestive of acute CSC in the RE and a pigment epithelial detachment (PED) in the left eye. Focal laser in RE lead to SRF resolution and visual improvement. He was on regular follow up and 5 years later he presented with a recurrence of CSC in the RE for which he underwent a repeat FFA guided focal laser. Conclusion: This case highlights the unique coexistence of CSC in the setting of Nanophthalmos and highlights a probable overlapping pathophysiology of choroidal venous overload as well as the importance of multimodal imaging in differentiating the mimicking entities.
