Our eyesight is one of our essential senses, helping us navigate the world. For people with high myopia (severe nearsightedness), there is a risk of developing a condition called Myopic Choroidal Neovascularisation (mCNV), which can lead to vision problems. Myopic Choroidal Neovascularisation (mCNV) is a condition that occurs in individuals with severe nearsightedness or high myopia. In this condition, abnormal blood vessels form beneath the retina in the choroid layer.
