In the early phase, the affected areas show hypoflurescence. Later, the borders of the lesions show staining along with fuzzy fluorescence at the edges of the lesions. Often times, this condition is asymptomatic until both eyes are involved, or until the macula is affected.
Acute lesions appear greyish with clear borders.
Lesions often extend from the perpapillary area, but they can sometimes occur in multiple areas. When a patient complains of visual symptoms, it is crucial to distinguish whether the decreased vision is due to neovascularization versus a foveal extension of fresh inflammation, since the treatment would be different. Previously affected areas often show scarring and atrophy. Recurrence can occur at any time after the initial attack and often involves larger areas, extending out from the edges of the inital attacks. Oral steroid or periocular injection of steroids may be helpful when an acute lesion involves the fovea or juxtafoveal area.
