· AIM: To evaluate the outcomes of pars plana vitrectomy (PPV) without the use of an ocular tamponade in patients having tractional retinal detachment (TRD) secondary to proliferative diabetic retinopathy (PDR). ·METHODS: It was an interventional study conducted at the Department of Ophthalmology, B.V. Hospital, Bahawalpur, Pakistan, from July 2011 to July 2012. A total of 75 patients (84 eyes) having TRD secondary to PDR were treated by PPV without using an ocular tamponade. All patients included in the study had a tractional retinal detachement secondary to proliferative diabetic retinopathy but didn’t have or develop retinal breaks before or during the study period. The surgical procedure included a PPV combined with the removal of the tractional retinal membranes and the application of endolaser photocoagulation to the retina. The mean follow-up period was 12 months. · RESULTS: Successful retinal reattachement was observed in 78 of the operated eyes (92.8% ). In these patients, the retina remained attached till the end of the one year follow -up period. Improvement in best corrected visual acuity (BCVA) was seen in 63 eyes (75% ).The visual acuity remained unchanged in 9 eyes (10.7% ). Mean improvement in BCVA was 2.00 +1.24 at baseline to 1.24+1.22 ( <0.05) at the end of the follow- up period. ·CONCLUSION: In the absence of the retinal breaks, a TRD secondary to PDR can be successfully treated by pars plana vitrectomy without the use of an ocular tamponade.
