Early laser photocoagulation combined with triamcinolone acetonide in treating macular edema secondary to temparal branch retinal vein occlusion

Objective To evaluate the effect of early laser photocoagulation combined with triamcinolone acetonide(TA) in treating macular edema secondary to temparal branch retinal vein occlusion.Methods A total of 42 patients(42 eyes) with macular edema secondary to temparal branch retinal vein occlusion diagnosed by fundus fluorescein angiography(FFA) and optical coherence tomography(OCT) were treated by TA and early laser photocoagulation.The changes were observed including the visual acuity,intraocular pressure,FFA and CMT in the first,third and sixth months after treatment. Results The visual acuity 6 months after treatment was improved in 37 eyes,remained the same in 4 eyes,and declined in 1 eye.The best corrected visual acuity was more than 0.3 in 11 eyes before treatment and 23 eyes after treatment.The CMT was(561±104) μm before treatment,and(349±93) μm 6 months after treatment(P0.01).The introaocular pressure increased in 2,6 and 1 eyes 1,3 and 6 months after treatment respectively,and became normal after eye drops administration for a short time.Conclusions Early laser photocoagulation combined with retrobulbar injection of TA is safety and effective in treating macular edema secondary to temparal branch retinal vein occlusion.
