a Color fundus photograph demonstrating a pigmented chorioretinal scar (outlined by white box) superior to the arcade with overlying contracted vitreous (Note: enhanced inset view of pigmented chorioretinal scar is postsurgical as demonstrated by surrounding laser photocoagulation scars since clear preoperative views were limited by vitritis).
