Bilateral cystoid macular edema misdiagnosed as pars planitis in a patient on sertraline therapy.

PURPOSE

To describe the presentation, clinical course and management of a patient with bilateral maculopathy associated with sertraline.

OBSERVATIONS

We report a rare case of bilateral cystoid macular edema and subretinal fluid in a 78-year-old Asian Indian female who was on chronic sertraline therapy. The patient was initially misdiagnosed as intermediate uveitis and started on oral corticosteroids. However, multimodal imaging with fluorescein angiography and optical coherence tomography ruled out ocular inflammation. There was symmetrical bilateral macular involvement and changes on macular electroretinography, which provided clues to the diagnosis of toxic maculopathy. After cessation of sertraline therapy, the retinal pathology reversed with improvement in visual acuity.

CONCLUSIONS AND IMPORTANCE

Development of cystoid macular edema due to sertraline is a very rare adverse event and must be considered by psychiatrists and ophthalmologists. Our case demonstrates this rare toxicity along with its imaging features, and reversal on cessation of sertraline therapy.
