Intravitreal triamcinolone treatment for macular edema associated with central retinal vein occlusion and hemiretinal vein occlusion.

Retina 2005 October
PURPOSE: To assess the efficacy of intravitreal triamcinolone treatment for macular edema from central retinal vein occlusion (CRVO) and hemiretinal vein occlusion (HRVO).

METHODS: This study was a retrospective medical records review of 24 eyes of 24 patients (mean age, 71 years) that were injected with 4 mg of intravitreal triamcinolone acetonide for treatment of macular edema due to CRVO (n = 21) and HRVO (n = 3). Of the 24 eyes, 14 were injected once, 6 were injected twice, 3 were injected 3 times, and 1 received 4 injections. Mean follow-up time was 10 months (range, 3-24 months). The average time between onset of symptoms and first injection was 5.4 months (range, 2-48 months). Available documents on pre- and postinjection optical coherence tomography central foveal thickness in 23 of 39 total injections were evaluated.

RESULTS: All injections resulted in reduction in central foveal thickness as determined by optical coherence tomography. The mean central foveal thickness decreased to 55% of preinjection values ([n = 23] 635 vs. 352 mum, respectively; P < 0.001). The average gain in visual acuity was 1.3 Snellen lines (range, -3-7) over the course of the study period. Ten eyes gained > or =2 lines of visual acuity, 3 eyes improved 1 line, 7 eyes remained the same, and 4 eyes worsened. There was no correlation between improvement in foveal thickness and corresponding visual gain (P = 0.24). None of the eyes of diabetic patients (n = 6) or patients with ischemic CRVO (n = 2) improved in visual acuity. The difference in mean baseline (20/167) and mean final visual acuity (20/91) was statistically significant (P = 0.015). The mean best postinjection visual acuity (20/67) was also significantly higher than the mean final visual acuity (P = 0.019). When diabetic and ischemic CRVO patients were excluded, the difference between mean baseline visual acuity and mean final visual acuity was found to be highly significant ([n = 16] 20/133 vs. 20/67, respectively; P < 0.001), while mean final and best postinjection visual acuities (20/50) did not differ (P = 0.085). Eight of 16 phakic eyes showed progression of cataract, 2 of which underwent cataract extraction. Nine of 18 patients without a history of glaucoma developed ocular hypertension and required glaucoma medication during postinjection follow-up. Trabeculectomy was performed on two eyes with glaucoma. Two other eyes developed epiretinal membranes, one of which underwent vitrectomy.

CONCLUSIONS: Intravitreal triamcinolone may be effective in treating macular edema from CRVO and HRVO. Subjects with concurrent diabetes or ischemic central retinal vein were less likely to have visual improvement.
