This condition is similar to MFC, and may be part of this disease's spectrum. Affected individuals are most often young, myopic females who complain of unilateral or bilateral paracentral scotomas. During the acute phase, small posterior yellow-white lesions are visible at the level of the RPE and choroid. Also, localized serous elevation of the retina or CNV can develop. In contrast to MFC, PIC patients have less vitreous cells and the lesions tend to occur in the posterior pole, often in the macular area.
Treatment is similar to multifocal choroiditis.
It's usually unilateral, but it can affect both eyes. The etiology is unknown. They occur at the level of the RPE and outer retina. They tend to cluster in the perimacular area and are less abundant outside the arcades. They may grow and become confluent.
