Abstract

Purpose: To evaluate the use of a slow-release dexamethasone 0.7-mg intravitreal implant for cystoid macular edema (CME) secondary to intermediate uveitis and refractory to systemic steroids. Methods: A retrospective study of the best-corrected visual acuity (BCVA), intraocular inflammation, intraocular pressure (IOP), fundus photography, optical coherence tomography (OCT), inflammation, and adverse reactions of five patients (women, mean age of 35 years) with cystoid macular edema treated with a dexamethasone implant. Patients were evaluated in seven visits until the 150th day after the implant. Results: Four patients had bilateral pars planitis and one had bilateral intermediate uveitis associated with juvenile idiopathic arthritis. Six dexamethasone devices were implanted, under topical anesthesia (one each in six eyes, five patients). The mean follow-up time was 5 months. The best-corrected visual acuity improved in all eyes that received an implant, with five having improvements of two or more lines. Optical coherence tomography showed thinning of the macula in all eyes treated, and we saw a correlation between the best-corrected visual acuity and retinal thinning. No serious adverse events occurred and no significant increase in intraocular pressure was observed. Conclusions: Slow-release dexamethasone intravitreal implants can effectively treat CME secondary to intermediate uveitis and refractory to systemic steroids.
