Selective laser trabeculoplasty complicated by cystoid macular edema: report of two cases.

PURPOSE Selective laser trabeculoplasty, a relatively novel treatment for open angle glaucoma, is frequently associated with mild post-operative intraocular inflammation. METHODS We report two uncommon cases of cystoid macular edema within a few weeks of routine selective laser trabeculoplasty. RESULTS Visual acuities and macular thicknesses of the two cases returned to baseline after medical treatment, but in one case, the cystoid macular edema persisted for months. CONCLUSION Cystoid macular edema after selective laser trabeculoplasty is fortunately a rare complication, but it might be more common in patients with predisposing factors, and it can be resistant to treatment.
