While ocular manifestations of CML are rare, the presentations can range from asymptomatic to sudden vision loss.

Examination of the right eye revealed a large intraocular mass.

At follow-up, a rhegmatogenous retinal detachment secondary to an atrophic hole in an area of prior subretinal infiltrates was noted. He underwent repair with a scleral buckle.
