Intravitreal triamcinolone acetonide for treatment of persistent macular oedema in branch retinal vein occlusion.
BACKGROUND
To evaluate the efficacy of intravitreal triamcinolone acetonide injection on persistent macular oedema in branch retinal vein occlusion that fails to respond to previous laser photocoagulation.


METHODS
A total of 19 eyes of 19 patients with persistent macular oedema due to branch retinal vein occlusion were treated with 8 mg/0.2 ml of intravitreal triamcinolone acetonide injection. The main outcome measures included best-corrected visual acuity, intraocular pressure, and macular oedema map values of Heidelberg Retinal Tomograph II (HRT II) before and after intravitreal triamcinolone injection.


RESULTS
The mean follow-up time was 6.2+/-1.0 months. The mean baseline best-corrected logarithm of minimal angle of resolution (LogMAR) value for visual acuities of the patients before intravitreal triamcinolone injection was 1.01+/-0.16. After treatment, it was 0.55+/-0.22 at the 1-month, 0.56+/-0.22 at 3-month, and 0.62+/-0.22 at the last visits and the differences were statistically significant when compared with baseline values (for each, P<0.001). The mean oedema map values on HRT II significantly decreased by 28.5% at 1-month, 23.8% at 3-month, and 23.8% at the last visit when compared with preinjection values (for each, P<0.001). Intraocular pressure elevation exceeding 21 mmHg was observed in 26.3% of eyes at 1-month, 15.7% at 3-month, and 5.2% at the last visit, but was controlled with topical anti-glaucomatous medications in all eyes.


CONCLUSIONS
Intravitreal triamcinolone acetonide application is a promising approach in the treatment of persistent macular oedema due to branch retinal vein occlusion non-respondent to laser photocoagulation.
