    ABSTRACT: To evaluate the therapeutic effect of intravitreal triamcinolone (IVT) injection for recent branch retinal vein occlusion (BRVO). In a randomized controlled clinical trial, 30 phakic eyes with recent (less than 10 weeks' duration) BRVO were assigned to two groups. The treatment group (16 eyes) received 4 mg IVT and the control group (14 eyes) received subconjunctival sham injections. Changes in visual acuity (VA) were the main outcome measure. VA and central macular thickness (CMT) changes were not significantly different between the study groups at any time point. Within group analysis showed significant VA improvement from baseline in the IVT group up to three months (P < 0.05); the amount of this change was -0.53 ± 0.46, -0.37 ± 0.50, -0.46 ± 0.50, and -0.29 ± 0.45 logMAR at 1, 2, 3, and 4 months, respectively. Corresponding VA improvements in the control group were -0.20 ± 0.37, -0.11 ± 0.46, -0.25 ± 0.58, and -0.05 ± 0.50 logMAR (all P values > 0.05). Significant reduction in CMT was noticed only in the treatment group (-172 ± 202 μm, P = 0.029) and at 4 months. Ocular hypertension occurred in 4 (25%) and 2 (14.3%) eyes in the IVT and control groups, respectively. A single IVT injection had a non-significant beneficial effect on VA and CMT in acute BRVO as compared to the natural history of the condition. The 3-month deferred treatment protocol advocated by the Branch Vein Occlusion Study Group may be a safer option than IVT injection considering its potential side effects.

    ABSTRACT: Central retinal vein occlusion (CRVO) is the most common vascular event in the eye after diabetic retinopathy. This study was conducted to evaluate the effect of intravitreal triamcinolone (IVT) on acute CRVO. In a randomized sham-controlled clinical trial, 27 eyes with recent onset (less than 2 months) CRVO were randomly assigned to two groups. The treatment group (13 eyes) received 4 mg IVT and the control group (14 eyes) received a sham subconjunctival injection. The outcomes were visual acuity (VA), occurrence of neovascularization of the iris (NVI), and central macular thickness (CMT) measured by optical coherence tomography. Examination was repeated 1, 2, 3, and 4 months after intervention. Mean (standard error) of CMT before, 2 and 4 months after injection was 565 (50), 259 (15), and 290 (53) microns in the treatment group and 629 (43), 470 (62) and 413 (59) microns in the sham group, respectively. The 2- month difference was significant (P=0.003). The difference between VA changes (0.39 logMAR) was significant only at 1 month (P=0.013). There was no meaningful difference in the occurrence of NVI between the two groups. The therapeutic effect of IVT on acute CRVO is greatest at months 1 and 2 with regard to VA and macular thickness, respectively, and decreases up to the 4th month.
