Choroidal Neovascular Membrane: Made Easy For Postgraduates
Introduction Choroidal neovascularization (CNV) or choroidal neovascular membrane (CNVM) is a growth of new choroidal vessels into the subretinal space through breaks in the Bruch's membrane. Ophthalmoscopically the CNVM appears as a greenish-grey lesion, often with a detachment of the sensory retina, subretinal blood, and exudates. Choroidal neovascularization can be multifactorial with the commonest being due to age-related macular degeneration (AMD), called the wet or exudative AMD. The other causes of include high myopia, angioid streaks, presumed ocular histoplasmosis syndrome, choroidal rupture post-trauma, osteoma, macular telangiectasia, inflammatory and idiopathic. Since the most common cause of CNVM remains age-related, this writeup will focus on the same. Age-related macular degeneration is the most common cause of blindness in the western world over the age of 65 years. With a worldwide UN estimate of about 20-25million, 8 million individuals are in the USA alone.1 The numb
