Ophthalmol Update Jan ;14(2):23-5.

Purpose: To report the visual outcome after pars plana vitrectomy in advanced diabetic eye disease (ADED). Material & Methods: This prospective case series was conducted at Al-Ibrabim Eye Hospital, Karachi from 6 Nov 2014 to 6 Nov 2015. 23G pars plana vitrectomy was performed in the diabetic patients with ADED from retina clinic. The patient were divided in three groups; Balance salt solution (BSS), C3F8 (Gas) and Silicon oil group, according to retinal status and use of intraocular tamponade. Best corrected visual acuity on Log MAR chart was recorded preoperative, 1week, 3 months and 6 months post operatively. Results: This prospective analysed 118 eyes, 8 patients (6.8%) were in C3F8 gas group, 35 patients (29.7%) balanced salt solution(BSS) and 75 patients (63.6%) silicon oil group. BCVA of all 8 patients (100%) in gas group, 33 patients (94.28%) BSS group and 37 patients (49.33%) silicon oil group were improved at 6 month postoperative follow up from the pre operative vision. While BCVA of 2 patients (5.71%) in BSS group, 32 patients (42.66%) silicon oil group remained same and 6 (8%) patients worsened at 6 month postoperative follow up from the preoperative visual acuity. CONCLUSION: Pars plana vitrectomy is an effective method to preserve visual acuity in ADED. Visual outcome shows better in PDR with vitreous hemorrhage but deteriorate with advancement of diabetic retinopathy as in PDR with TRB and TRD.
