Medical treatment of macular edema in patients with uveitis

Abstract

Purpose: To determine the efficacy of medical treatment of cystoid macular edema (CME) in patients with uveitis.

Methods: Retrospective study of 40 patients (57 eyes) with uveitis and CME. Inclusion criteria were presence of CME with minimal and no macular pathology, or vascular disease which could account for CME. Patients who had undergone intraocular surgery or had visual acuity (VA) of > or = 20/40 were excluded. The diagnosis of CME was based on clinical and/or angiographic findings. Three treatment groups were defined: (1) transseptal injection of steroids (n=13 eyes); (2) systemic non steroidal anti-inflammatory drugs (NSAIDs) (n=11 eyes); both 1 and 2 (n=33 eyes).

Results: Overall, 79% of eyes improved 3 or more lines of Snellen VA after treatment: 51% improved 4 or more lines. The average number of lines improved was 3.8 for eyes treated with transseptal injections of steroids, 2.9 for eyes treated with NSAIDs, and 4 for eyes treated with both. For all 3 treatment groups between 60-70% of eyes improving 2 or more lines reached best VA only after a minimum of 6 months of follow up.

Conclusions: CME, a vision threatening complication of uveitis, respond fairly well to medical treatment; however, the best VA is achieved after several months. The improvement in VA did not differ markedly among the three treatment groups.
