LLANES DOMINGUEZ, Silvio et al. Intravitreal injection of triamcinolone acetonide for treament of macular edema secondary to branch retinal vein occlusion. Rev Cubana Oftalmol [online]. 2013, vol.26, n.3, pp. 439-451. ISSN 0864-2176.

Objectives: To evaluate the results of the treatment with intravitreal injection of triamcinolone acetonide of a macular edema secondary to branch retinal vein occlusion. Methods: Prospective, interventional and non-comparative study of 16 patients with macular edema secondary to branch retinal vein occlusion. The treatment consisted of intravitreal injection of triamcinolone (up to three doses) and if third retreatment was necessary, then macular grid was performed. The first dose was injected three months after occlusive event and followed-up for 12 months. The best corrected visual acuity, the retinal foveal thickness and the complications were determined. Results: Eleven men (68.75%) and 5 women (31.25%) with average age of 60.1 years were studied. Of the total number of patients, 8 required one dose (50%), 5 needed two doses (31.25%) and 3 required three doses (18.75%) plus macular grid. The best initial corrected average visual acuity was 0.29 (0.05-0.5), which improved to 0.64(0.05-1.0) after 12 months. The initial average retinal foveal thickness was 551.38 (346-967) µm and decreased to 204.06 (112-449) µm after 12 months. The most frequent complication was ocular hypertension in 4 patients (25%). Conclusion: The intravitreal injection of triamcinolone acetonide was an effective treatment of the macular edema secondary to the branch retinal vein occlusion.
