Diabetic tractional retinal detachment repair by vitreoretinal fellows in a county health system.

PURPOSE: To investigate anatomical and functional outcomes of vitreoretinal fellow-performed vitrectomy for tractional retinal detachment secondary to proliferative diabetic retinopathy in a county hospital system.

METHODS: Consecutive retrospective review of patients surgically treated for diabetic tractional retinal detachment at Olive View-UCLA County Medical Center (Sylmar, CA) during a 2-year training period.

RESULTS: Sixty-two eyes of 58 patients met inclusion criteria with a mean age of 48 ± 9 years and preoperative hemoglobin A1c of 8.4 ± 1.9%. Previous panretinal photocoagulation had been performed in 34 eyes (54.8%). Mean surgery duration was 153 ± 54 minutes. There was no significant time difference observed between first-year fellow surgeries (159.5 ± 52.3 minutes) and those performed by second-year fellows (146.8 ± 56.4 minutes, P = 0.35), although there was a trend toward longer first-year surgical times. After a mean follow-up of 11.2 months, successful retinal reattachment was achieved in 56 eyes (90.3%). Overall, mean logMAR visual acuity improved from 2.0 ± 0.5 to 1.4 ± 0.8 (P = 0.0007). Final visual acuity had improved in 33 eyes (53.2%), was unchanged in 11 eyes (17.7%), and decreased in 18 eyes (29%). Postoperative complications encountered included early vitreous hemorrhage in 10 eyes (16.1%), delayed vitreous hemorrhage in 3 eyes (4.8%), secondary rhegmatogenous retinal detachment in 11 eyes (17.7%), and neovascular glaucoma in 5 eyes (8%). Second-year fellows had a lower incidence of rhegmatogenous retinal detachment than first-year fellows (P = 0.016).

CONCLUSION: Patients with diabetic tractional retinal detachment present to county hospitals with more complex retinal pathology, yet surgical outcomes as performed by vitreoretinal fellows compare favorably to previously reported series.
