Intravitreal bevacizumab in refractory uveitic macular edema: one-year follow-up.
OBJECTIVE
Uveitis is a major cause of ocular morbidity in developed countries. It has been demonstrated that macular edema is a significant cause of decreased visual acuity and macular edema in these patients. In this article, we evaluate the long-term outcome of intravitreal bevacizumab in the treatment of refractory uveitic macular edema.


METHODS
In this retrospective, noncomparative, interventional case series, uveitic patients with macular edema who were refractory to conventional therapy and who were treated with intravitreal bevacizumab were identified and assessed. Best-corrected visual acuity and optical coherence tomography central macular thickness measurements were collected and analyzed with correlative statistical analysis, including the use of Student paired t-test, Kaplan-Meier, and linear regression analysis.


RESULTS
Twenty-nine eyes of 27 patients with diverse uveitic etiologies were analyzed and followed up at 1 year. Thirteen patients received a single intravitreal bevacizumab injection. Six patients required a second intravitreal bevacizumab injection, while 10 patients received combination therapy of intravitreal bevacizumab and triamcinolone acetonide. Baseline mean logMAR visual acuity was -0.59. At 1 year, the mean logMAR visual acuity was -0.42-/+ 0.36 (p=0.0045). Baseline mean central macular thickness was 383.66 microm. At 1 year, the mean thickness was 294.32-/+110.87 (p=0.0007).


CONCLUSIONS
Intravitreal bevacizumab is a useful and therapeutically beneficial agent in the treatment of refractory uveitic macular edema. Some patients will require adjunctive intravitreal bevacizumab injections or the use of combination therapy with intravitreal triamcinolone acetonide.
