ABSTRACT
We retrospectively analyzed a consecutive series of 36 eyes that underwent vitrectomy for complications of proliferative diabetic retinopathy after classifying according to the preservationof their lenses to determine the postoperative incidence of neovascular glaucoma and final visual outcome. Eyes in which the lens was removed had better visual results than eyes in which the lens was not removed even though they were not statistically significant. There was statistically no difference in the postoperative incidence of neovascular glaucoma between both groups. But, eyes treated with preoperative panretinal photocoagulation had a statistcally significant increase in the incidence of postoperative glaucoma compared to eyes treated with operative one of add laser. This study showed that the eyes undergone vitrectomy combined with lensectomy as well as the eyes undergone only vitrectomy had improved visual outcomes.
