AIM:To investigate the postoperative vision in rhegmato-genous retinal detachment(RRD),and its influencing factors.·METHODS:All 99 patients(102 eyes) with RRD that underwent surgical management in our hospital from January 2002 to October 2007 were retrospectively analyzed.81 eyes underwent surgical management of scleral buckling and 21 eyes underwent surgical manage-ment of vitreoretinal surgery.Age,area of retinal detachment,course,proliferative vitreoretinopathy(PVR),involvement of the macular region in the detachment,refraction,position of break,visual acuity,situation of the break and its closure on retina and retinal replacement of patients were observed.Chi-square test was performed to analyze the postoperative vision and influencing factors,for example age,area of retinal detachment,course,proliferative vitreoretinopathy(PVR),situation of the macular and refraction.According to the results,the significative factors were analyzed with Spearman test.·RESULTS:Improved postoperative vision was observed in 53 eyes (52.0%),invariable vision was observed in 33 eyes(32.3%),and descended vision was observed in 16 eyes (15.7%).The situation of postoperative vision had significant difference in different PVR grade,macular situation,area of retinal detachment,course and age (P<0.05),and the connections between postoperative vision and influencing factors were as follows:PVR grade(rs=-0.521,P=0.000),macular situation(rs=-0.446,P =0.000),course(rs=-0.423,P =0.000),area of retinal detachment(rs=-0.411,P=0.000),age(rs=-0.267,P =0.007).·CONCLUSION:Postoperative vision improvement was related with PVR grade,macular situation,course,area of retinal detachment,and age,preoperative PVR grade,macular situation,and course are the most important influencing factors to postoperative vision.
