Pars Plana Vitrectomy without endotemponade in Proliferative Diabetic Retinopathy leading to Tractional Retinal Detachment: An audit of 73 cases.
Pak J Surg Jan ;31(1):70-3.

Purpose: To evaluate the outcomes of pars plana vitrectomy in patients with proliferative diabetic retinopathy (PDR) causing Tractional Retinal Detachment (TRD) without use of endotemponade. Methodology: Th is descriptive, retrospective case series includes 73 eyes with TRD secondary to PDR Th ey were consecutively operated at department of Ophthalmology of Dow University of Health sciences, Civil Hospital Karachibetween January 2006 to June 2012. All surgeries were performed under general anaesthesia by three port pars plana vitrectomy using fl uid–air exchange and endolaser. Th e patients were followed up on day 1, one week, one month, three months and fi nally at six months. Best corrected Visual acuity; intraocular pressure and anatomical status of retina were noted on each visit. Data were entered on SPSS version 17 for statistical analysis. P value of 0.05 was considered statistically signifi cant. Results: Total 73 patients underwent for surgery, out of which 33(45%) were male and 40(55%) were female. Mean age of patients was 44.46±20.83 years (range was 20-59 Years). Most common indication for vitrectomy was Proliferative diabetic retinopathy (PDR). Mean pre operative visual acuity was on HM and mean post-operative visual acuity was 6/60 according to Snellen Visual Acuity Chart. A signifi cant improvement was noted in visual acuity recorded pre-operatively and post operatively (p=0.001). Conclusion: TRD secondary to PDR can be treated successfully with pars plana vitrectomy without using ocular endotamponade provided there is no retinal break.
