Prevalence and rik factor for proliferative vitreoretinopathy in eye with rhegmatogenou retinal detachment but no previou vitreoretinal urgery

Purpoe To determine the prevalence of and rik factor for proliferatative vitreoretinopathy (PVR) in eye with rhegmatogenou retinal detachment but no previou vitreoretinal urgery. Deign Obervational cae erie. Method Propective tudy. etting A private vitreoretinal clinic in Caraca, Venezuela. tudy population 119 eye of 119 patient who preented with rhegmatogenou retinal detachment but no previou vitreoretinal urgery between 1995 and 1998. Obervation procedure Data from detailed preoperative and potoperative examination of each eye were recorded propectively and entered into an electronic databae. Main outcome meaure Prevalence of PVR of any type and evere PVR, preoperative rik factor for PVR of any type and evere PVR, effect of PVR and retinal detachment duration on initial and final viual acuity, and urgical complexity. Reult The prevalence of PVR of any type wa 52.9% and of evere PVR wa 26.9%. The mean retinal detachment duration (±D) wa 58.4 (±129.1) day, and the mean time from initial examination to urgical treatment (±D) wa 24.3 (81.2) day. By univariable analyi, long retinal detachment duration, poor initial viual acuity, and large retinal detachment extent were ignificantly aociated with PVR prevalence and everity. The preence of vitreou hemorrhage wa ignificantly aociated with PVR prevalence, and cataract wa ignificantly aociated with PVR everity. By multivariable analyi, long retinal detachment duration and large retinal detachment extent were imultaneou rik factor for PVR prevalence, while long retinal detachment, large retinal detachment extent, and poor initial viual acuity were imultaneou rik factor for PVR everity. Eye with longer retinal detachment duration, PVR of any type, and evere PVR had wore initial and final viual acuitie than eye with horter retinal detachment duration or thoe without PVR, repectively. Eye with PVR had more complex urgery than thoe without PVR. Concluion PVR occurred very frequently in thi population and wa aociated with more complex urgery and wore viual outcome than among eye without PVR. We have identified preventable rik factor aociated with PVR that ugget a pecific and ignificant need for better acce to ophthalmologic care and patient education in thi group of patient.
