Mesangial proliferative glomerulonephritis

Central serous chorioretinopathy (CSC), also known as central serous retinopathy, is a granulomatous inflammation of the choroid that leads to damage of Bruch's membrane (a thin, membrane-like structure located between the choriocapillaris and the retinal pigment epithelium). This damage compromises its barrier function, allowing choroidal neovascularization to penetrate through defects in Bruch's membrane into the subretinal pigment epithelium space or subretinal neurosensory epithelium. This condition commonly affects young and middle-aged adults, with an onset age typically between 32 and 38 years. It usually affects one eye, though a small number of cases involve both eyes. The main symptoms include decreased central vision, metamorphopsia (distorted vision), micropsia (objects appearing smaller), and central scotoma (a blind spot in the central visual field), which can lead to permanent vision impairment.
