Metamorphopsia is a type of distorted vision in which a grid of straight lines appears wavy and parts of the grid may appear blank. People with this condition often first notice this when looking at mini-blinds in their home.
It is mainly associated with macular degeneration, particularly age-related macular degeneration with choroidal neovascularization.[1] Other conditions that can present with complaints of metamorphopsia include pathological myopia, presumed ocular histoplasmosis syndrome, choroidal rupture and multifocal choroiditis.[1]
Etymology

However, these studies are limited in that they have focused on older adults, used a convenient sample, and/or used a subjective assessment of visual function. As a result, th
