Ciliary Body Melanoma

TB is a 43-year-old man with complaints of a film over part of the vision in his right eye for several months. It had seemed to descend from the lower part of his visual field and grow upwards into the center of his vision. Examination demonstrated best corrected vision in his right eye of 20/60-2 and in his left eye of 20/20. His pupils were equal in size and reactive to light without an afferent defect. Slit-lamp examination discovered a sectorial cortical and posterior capsular lens opacity in the superior part of his lens that was encroaching into the visual axis. Dilated fundus examination was unremarkable with a normal retinal periphery. Because of his relatively young age and the unusual nature of the lens opacity, he was referred for immersion ultrasound examination.
