Bilateral macular sub-retinal fluid and retinal pigment epithelial detachment associated with type 2 membrano-proliferative glomerulonephritis.

Choroidal neovascularisation (CNV) and idiopathic central serous chorioretinopathy (ICSC) are recognised ocular complications related to type 2 membrano-proliferative glomerulonephritis. We report a 38-year-old white male who presented with a 10-day history of blurring of vision, micropsia and metamorphopsia. He had been diagnosed recently to have type 2 membrano-proliferative glomerulonephritis. On examination, there was bilateral retinal pigment epithelial (RPE) detachment with overlying sub-retinal fluid without any drusen. Fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) confirmed the diagnosis of atypical ICSC. Three months later, sub-retinal fluid and RPE detachment resolved and VA had recovered to 6/6. The case highlights the importance of ophthalmological assessment in these patients to recognise sight-threatening complications.
