Combined treatment of intravitreal triamcinolone enjection and grid laser photocoagulation in eyes with macular edema after branch retinal vein occlusion

Retinal vein occlusion is the second most common retinal vascular disease after diabetic retinopathy. in this study, we investigate the effect of treatment of intravitreal triamsinolon with laser photocoagulation in eyes with macular edema after branch retinal vein occlusions (brvo).retrospective medical record review of 14 patients who underwent combine intravitreal triamcinolone acetonide enjection and grid laser photocoagulation for macular edema was conducted between october 2007 and february 2009. macular edema was confirmed by fundus fluorescein angiography and optical coherence tomography. patients received an intravitreal injection of 0.1 ml (4 mg) triamcinolone acetonide and grid laser photocoagulation was followed 1 month later. all of patients underwent a detailed ophthalmic examination included best corrected visual acuity, anterior and posterior segment biomicroscopy with a slit-lamp biomicroscopy, intraocular pressure. the mean age of the study patients was 56.3±7.3 years.there were 11 (79%) females and 3 (21%) were males. a total of 8 of the study eyes (57%) were superotemporal quadrant and 6 eyes (43%) were inferotemporal quadrant. visual acuity compared before treatment increased one or more line in 6/14 patient (43%) on third month, and 8/14 patient (57%) on six months. visual acuity constant remained 4/14 cases (29 %), and decreased one line only one patient (7%) on follow-up time. during 6 months follow-up period glaucoma was occured in 3/14 patients (21%), and cataract in one patient (7 %). as a result of the treatment of intravitreal triamcinolone and grid laser photocoagulation in eyes with macular edema after brvo may be useful at the reduce of macular edema, and may increase visual acuity in the short term.
