Metamorphopsia

Metamorphopsia (from Ancient Greek: μεταμορφοψία, metamorphopsia, 'seeing mutated shapes') is a type of distorted vision in which a grid of straight lines appears wavy or partially blank. In addition, metamorphopsia can result in misperceptions of an object's size, shape,^[3] or distance to the viewer. People can first notice they suffer from the condition when looking at mini blinds in their home.^{[citation needed]}

Initially characterized in the 1800s, metamorphopsia was described as one of the primary and most notable indications of myopic and senile maculopathies.^[4] Metamorphopsia can present itself as unbalanced vision, resulting from small unintentional movements of the eye as it tries to stabilize the field of vision.^[4]

It is mainly associated with macular degeneration, particularly age-related macular degeneration with choroidal neovascularization.^[5] Other conditions that can present with complaints of metamorphopsia include: pathological myopia, presumed ocular histoplasmosis syndrome, choroidal rupture and multifocal choroiditis.^[5]
