Purpose:The macular edema is one of the major causes of visual impairment in case of branch retinal vein occlusion (BRVO). The relationship between the vitreous and macula is known to affect the visual outcome. The present study aims to evaluate the role of posterior vitreous status in affecting the visual results of laser photocoagulation. Methods:Forty-six patients affected by BRVO were studied. We evaluated the status of posterior vitreous detachment and compared the result of grid laser photocoagulation between the two groups (with or without posterior vitreous detachment). Results:The visual improvement was achieved in only 50 % of eyes without posterior vitreous detachment compared with 71.4 % of eyes with posterior vitreous detachment. Conclusion:This results show that the visual outcomes of grid laser photocoagulation are affected by the status of posterior vitreous.
