Abstract: : Purpose: To report optical coherent tomographic findings of branch retinal vein occlusion (BRVO) with serous macular detachment and the effect of laser treatment. Methods: We retrospectively studied 22 eyes of 22 patients with BRVO, whose eyes had serous macular detachment detected by optical coherent tomography (OCT). We performed panoramic fluorescein angiography in 19 of 22 eyes to evaluate the occluded area and the degree of dye leakage before treatment. Fourteen of 22 eyes underwent scatter laser photocoagulation to the BRVO area. We observed the serial OCT findings before and after treatment. Results: Superotemporal vein was occluded in 15 eyes (including macular branch occlusion in 5 eyes) and inferotemporal vein was involved in 7 eyes. Extensive dye leakage was observed in the BRVO area in all examined eyes (19 eyes). Partial occlusion of perifoveal capillary network was detected in all 19 eyes. The OCT demonstrated serous macular detachment with retinal swelling in 9 eyes and the remaining 13 eyes had serous macular detachment with cystoid macular edema (CME). The area of occlusion of perifoveal capillaries in the former 9 eyes was smaller than that in the latter 13 eyes. The corrected visual acuity ranged from 0.04 to 0.6, average 0.19 before laser treatment. Laser photocoagulation was done in 14 of 22 eyes. Serous macular detachment was well responded to laser treatment, that resulted in improved visual acuity more than 2 lines in 8 of 14 eyes. The average period of resolution of macular detachment was 3.7 months after photocoagulation. Conclusions: Serous macular detachment is one of the patterns of macular edema in BRVO. Serous macular detachment was prevalent if the venous occlusion occurs at the superotemporal branch and/or extensive extravasation in the BRVO area. Serous macular detachment with CME develops in case of BRVO with wide occlusion of perifoveal capillary network. Scatter laser photocoagulation is indicated for early resolution of serous macular detachment.
