Purpose: To study the rate of vitrectomy in the fellow eye of patients undergoing primary vitrectomy for complications of proliferative diabetic retinopathy (PDR). Methods: A retrospective study was done on 283 consecutive patients requiring primary diabetic vitrectomy performed by one vitreoretinal surgeon at the Kresge Eye Institute. The primary vitrectomies were categorized into 3 distinct groups based on operative findings: (i) TRD/RRD (47/283)–combined tractional–rhegmatogenous retinal detachment (with or without vitreous hemorrhage); (ii) TRD (150/283)–tractional retinal detachment (with or without vitreous hemorrhage); and (iii) VH only (65/283)–nonclearing vitreous hemorrhage only. Preoperative characteristics, diagnoses, procedures, and factors predictive of fellow eye vitrectomy were analyzed. Results: Sixteen percent (45/283) of patients undergoing primary diabetic vitrectomy required vitrectomy in the fellow eye. The average time to vitrectomy in the fellow eye was 8 months. Twenty–eight percent of patients with TRD/RRD (13/47); 18% of patients with TRD (27/150); and 8% of patients with VH only (5/65), required vitrectomy in the fellow eye. The fellow eyes requiring vitrectomy had a TRD/RRD in 13% (6/45); a TRD in 69% (31/45); and VH only in 18% (8/45). Conclusions: Despite close follow up and extensive panretinal photocoagulation after undergoing primary vitrectomy, a considerable percentage of patients required fellow eye vitrectomy. The rate of vitrectomy in the fellow eye of 283 consecutive patients undergoing diabetic vitrectomy was 16% (45/283) at an average of 8 months after primary vitrectomy. Patients with TRD/RRD were more likely to require fellow eye vitrectomy. TRD/RRD is an advanced complication of PDR and may represent a risk factor for fellow eye vitrectomy.
