Steroid-responsive serous retinal detachment in undetected chronic lymphocytic leukemia

A 69-year-old diabetic man, treated intermittently with oral and periocular corticosteroids for suspected left eye choroiditis for past one year, presented with decreased vision in left eye. We noted best-corrected visual acuity (BCVA) of 20/35 and 20/30 in right and left eyes, respectively. Right lens was cataractous and left pseudophakic. Right fundus was normal while left showed shallow serous detachment around optic disc with underlying focal choroidal lesions. Blood investigations revealed markedly raised leukocyte count with marked lymphocytosis. Bone marrow cytology confirmed B-cell chronic lymphocytic leukemia. The patient′s ocular and systemic condition resolved with rituximab and bendamustine chemotherapy
