Exudative retinal detachment secondary to orbital and intraocular benign lymphoid hyperplasia

A 69-year-old white woman presented with glaucoma secondary to benign lymphoid hyperplasia and elevated episcleral venous pressure. Retinal detachment developed subsequent to trabeculectomy and cataract formation. A biopsy of orbital tissue that surrounded the vortex veins revealed mature lymphocytes. Cytology of subretinal fluid also revealed the presence of lymphocytes. Radiation therapy resulted in absorption of subretinal fluid.
