Small choroidal melanoma with massive extraocular extension: invasion through posterior scleral emissary channels

Massive orbital extension arising from a small posterior pole uveal melanoma is rare. A 75-year-old male followed for an asymptomatic choroidal nevus developed a two and a half month history of mild decrease in visual acuity. Upon clinical examination minimal enlargement of the tumor with surroundin...
