Abstract:
Objective To determine the risk factors of light perception and no light perception appearenee after vitrectomy for pro-liferative diabetic retinopathy (PDR). Design Retrospective, noncomparative case series. Participants 242 patients (288 eyes) who un-derwent vitrectomy for PDR. Methods 288 eyes of participants from 2002 to 2006 at Beijing Tongren Eye Center were reviewed. Cases that had postoperative visual acuity of light perception (LP) and no light perception (NLP) were recorded and PDR stages, traction reti-nal detachment involving macula, postoperative retinal detachment, postoperative vitreous hemorrhage, postoperative neovascular glauco-ma and re-operations were analyzed. Main Outcome Measures Postoperative complications, PDR stage, macular disorder. Results Subjects were divided into two groups. LP/NLP group included eyes that had postoperative visual acuity of light perception and no light perception (totally 14 eyes in this group). Another group (control group) included eyes that had postoperative visual acuity of hand mo-tion or better (totally 274 eyes in this group). When compared with control group, the LP/NLP group had significantly higher prevalence of PDR 6, traction retinal detachment involving macula, postoperative retinal detachment, postoperative vitreous hemorrhage, postopera-tive neovascular glaucoma and reoperation (P value was 0.042, 0.048, 0.048, 0.000, 0.000, 0.000, respectively). Conclusion Risk factors of light perception and no light perception after vitrectomy for PDR include PDR stage 6, traction retinal detachment involving macula, postoperative retinal detachment, postoperative, vitreous hemorrhage, postoperative neovascular glaucoma and re-operation.
