Multifocal choroiditis and panuveitis (MCP) is an idiopathic inflammatory disorder of the vitreous, retina, and choroid most common in young myopic women. Characteristic findings include punched-out white-yellow dots (50-200 µm) throughout the fundus and vitritis, which helps to differentiate the condition from other similar-appearing entities such as presumed ocular histoplasmosis syndrome (POHS) and punctate inner choroiditis (PIC). The lesions eventually turn into atrophic scars with variable amounts of hyperpigmentation. Peripheral chorioretinal streaks can sometimes be visualized, as seen in these photographs.
