Abstract: :
Purpose: To describe the visual outcome of patients who underwent vitrectomy suregry for proliferative diabetic retinopathy at Kresge Eye Institute. Methods: We conducted a retrospective chart review of 100 consecutive diabetic vitrectomies performed by a single surgeon at Kresge Eye Institute over a period of 18 months. The primary indication for surgery was documented for each case. These indications were 1) non-clearing vitreous hemorrhage (VH), 2) tractional retinal detachment involving the fovea (TRD), or 3) both tractional and rhegmatogenous retinal detachment (TRD + RRD). Visual acuities were documented as following: V0 (pre-op vision), V1 (vision on post-op day 1), V2 (one week), V3 (one month) and V4 (final best corrected vision). Descriptive statistics were then used to compare the visual acuities for each primary indication. Results: Vitreous hemorrhage was the indication in 37.5% of the patients, TRD was the indication in 52.3% of the patients, and TRD + RRD was the indication in 10.2% of the patients. Visual acuity improved in 84.8% of patients with VH, 50% of patients with TRD involving the fovea, and 33.3% of patients with TRD + RRD. The visual acuities over time for the three indications were also compared. Conclusions: Patients with the primary indication of TRD + RRD for vitrectomy surgery appear to have the worse visual prognosis, whereas patients with vitreous hemorrhage appear to have the best visual prognosis.
