Purpose: To evaluate factors influencing visual outcomes of vitrectomy with arteriovenous (A/V) sheathotomy for macular edema in branch retinal vein occlusion (BRVO) using multiple logistic regression analysis. Methods: Thirty–eight eyes of 38 consecutive patients with macular edema and BRVO underwent vitrectomy with A/V sheathotomy. A multiple logistic regression analysis was carried out to analyze factors prognostic of better postoperative visual acuity. Independent variables were patient age, preoperative visual acuity, intravitreal injection of triamcinolone acetonide (TA) at the end of surgery and duration of symptoms. Results: Acquisition of the postoperative visual acuity of 0.5 or better was significantly dependent on the patient age (odds ratio; 7.77, p=0.04) and the preoperative visual acuity (odds ratio; 22.85, p=0.01). Intravitreal injection of TA was not significantly associated with better postoperative visual acuity. Conclusions: Our results suggest that factors prognostic of better postoperative visual acuity could be patient age and preoperative visual acuity. Intravitreal injection of TA at the end of surgery might not influence visual outcome.
