Cystoid macular edema in a patient with acquired immunodeficiency syndrome and past ocular history of cytomegalovirus retinitis after initiation of protease inhibitors.

OBJECTIVE

To describe a patient with acquired immunodeficiency syndrome (AIDS) who presented with cystoid macular edema (CME) which was not associated with active cytomegalovirus (CMV) retinitis or AIDS-related microvasculopathy.

METHODS

A 32-year-old man with AIDS and a past ocular history of inactive CMV retinitis was placed on protease inhibitors when his CD4+ T lymphocyte counts dropped to 8 cells/mm3. Three months later, after his CD4+ T lymphocyte counts had increased to 196 cells/mm3 he complained of micropsia and metamorphopsia in his right eye of 1 week duration. The patient had a complete ocular examination including fluorescein angiography (FA).

RESULTS

Visual acuity (VA) was 7/10 OD. Fundus examination revealed CME and inactive CMV retinitis, and FA demonstrated CME and a hot disc. Two transseptal injections of corticosteroids were administered 2 weeks apart in the right eye as treatment of the CME. The patient reported gradual visual improvement and 6 weeks later, his VA was 10/10(-2). CME had resolved clinically and angiographically.

CONCLUSIONS

CME in our case is associated with inactive CMV retinitis and gradually increasing number of CD4+ T lymphocytes after initiation of treatment with protease inhibitors. It may be amenable to regional administration of corticosteroids without reactivation of retinitis.
