Abstract

PURPOSE
We evaluated the effect of vitrectomy and arteriovenous adventitial sheathotomy for branch retinal vein occlusion (BRVO) according to operation timing and obstruction site. METHODS: We performed vitrectomy and arteriovenous adventitial sheathotomy in 14 eyes with BRVO. Patient selection criteria were foveal involvement of macular hemorrhage or macular edema and a best corrected visual acuity (BCVA) of 0.1 or less. We compared 7 eyes with symptom duration of 2 months or less (Group 1) and 7 eyes with symptom duration of more than 2 months (Group 2). We analyzed 7 eyes for which the obstruction site was 1 disc diameter (DD) or less from the disc margin (Group A) and 7 eyes of more than 1 DD (Group B). RESULTS: Seven of 14 eyes (50%) had visual improvement. Six eyes of Group 1 (86%) had visual improvement and Group 1 had better visual improvement than Group 2. There was a statistically significant difference between Groups 1 and 2 (p=0.029). Five eyes of Group A (71%) had visual improvement and Group A had better visual improvement than Group B. There was no statistically significant difference (p=0.286). CONCLUSIONS: In the case of foveal involvement of macular hemorrhage or macular edema and a BCVA of 0.1 or less, vitrectomy and arteriovenous adventitial sheathotomy are effective in early BRVO.
