Eye findings have been reported in up to 50-80% of the patients with TSC. The retinal lesions of TSC are hamartomas (elevated mulberry lesions or plaque-like lesions) and white depigmented patches (similar to the hypopigmented skin lesions). Most retinal hamartomas remain dormant, thus patients with retinal lesions seldom develop progressive visual loss. Occurrence of visual loss due to retinal detachment, vitreous hemorrhage, or hamartoma enlargement is rare. Hypopigmented areas of the retina, iris and even the eyelashes have also been reported.
