Seven Important OCT Signs in CNVM
1. Type of macular neovascularisation (MNV): Macular neovascularisation (MNV) is a broad disease entity characterised by the development of the abnormal vessels arising either from the retinal vasculature (deep capillary plexus) or choroidal vasculature (choriocapillaris). Choroidal neovascular membrane (CNVM) is a subtype of MNV, characterised by the abnormal growths of blood vessels from the choroidal capillaries that penetrate the retina, specifically into the sub-RPE and subretinal spaces. These vessels are extremely immature and extremely fragile, so they bleed and leak, de-structuring the macula, causing severe visual impairment. The classification of MNV is depicted below in Figure 1: Figure 1: A simple classification of macular neovascularisation (MNV): 2. Cause of CNVM: A CNVM is primarily classified based on the etiology into two categories: A) Age-related Macular Degeneration (AMD) associated CNVM and B) Non-AMD associated CNVMs. Causes of non-AMD associated CNVMs: Central s
