Inferior staphyloma syndrome, also known as tilted disc syndrome. A, Color fundus photograph shows that the color of the superior fundus is darker than the staphylomatous inferior staphyloma. At the border between the two regions (arrowheads) there is a pigmentary change in the macula (yellow arrow). Because this border runs through the superior border of the optic nerve head, the patient has a tilted disc (arrow). B, A vertical OCT taken through the fovea shows the two curves. At the ridge between them, there is choroidal neovascularization (arrow) associated with a small amount of submacular fluid. The sclera is typically thicker at the border zone (asterisk) than anywhere in the neighboring areas.
