Abstract

Purpose: To investigate the long-term visual outcomes of patients undergoing pars plana vitrectomy for diabetic retinopathy-related complications and determine factors that predict final visual acuity.

Design: Retrospective study of 37 eyes in 33 diabetic patients who underwent pars plana vitrectomy (PPV) for diabetic retinopathy at a single institution. The study included patients with type 1 or 2 diabetes mellitus who had PPV for persistent vitreous hemorrhage or macula-threatening tractional retinal detachment. Surgeries were performed by the same vitreoretinal surgeon using standard 23-gauge needle vitrectomy, and complete pan-retinal photocoagulation was performed in all cases.

Results: A study analyzed data from 37 eyes over an average 4.84 ± 2.74 years. Most had type 2 diabetes and were treated for macula-threatening tractional retinal detachment or non-clearing vitreous hemorrhage (NCVH). Visual acuity improved in year 1 and remained stable at 5 years. Only 6 eyes needed vitreous washout. Regression models revealed 6-month visual acuity as the sole predictor for final visual acuity in years 2 and 5.

Conclusions: This study adds to existing knowledge about long-term outcomes in diabetic eyes undergoing vitrectomy for NCVH and macula threatening TRD. Most eyes show positive 2- and 5-year visual outcomes, regardless of the initial reason for surgery. 6-month VA appears to be the strongest predictor of final VA. Further research is needed to identify baseline ocular characteristics using objective metrics to better predict surgical benefits.
