In pancreas recipients with advanced diabetic eye disease, conflicting ophthalmologic results over different follow-up periods have been reported. In the present prospective study we performed ophthalmologic evaluation groups of type I diabetic patients: 1) normoglycemic recipients of pancreas and kidney grafts (group SPK, n = 43, follow-up 44.9 ± 35.1 months), 2) pancreas and kidney graft recipients with nonfunctioning pancreatic graft, and recipients of isolated kidney graft (group K, n = 45, follow-up 60.3 ± 34.2 months). The examinations were performed before transplantation, at the end of follow-up (at least 1 year), and in 63 recipients also at 3 years posttransplant. Visual acuity results at baseline and at the end of follow-up were 0.48 ± 0.39 vs. 0.50 ± 0.39 in the SPK group, and 0.46 ± 0.38 vs. 0.40 ± 0.39 in the K group. While intragroup changes were not significant, the changes were significantly different between the groups (p < 0.05). Fundoscopic findings at the end of follow-up were improved, stabilized, or deteriorated in the SPK group in 21.3%, 61.7%, and 17.0%, respectively. The respective figures for the K group were 6.1%, 48.8%, and 45.1% (p < 0.001). Similar results were obtained when evaluating findings at 3 years posttransplant. Before transplantation, 78% of the SPK group and 81% of the K group had been treated by laser. The need for additional posttransplant laser therapy was significantly lower in the SPK (31%) than in the K group (58%; p < 0.001). In conclusion, pancreas transplant exerts a beneficial effect on the course of diabetic retinopathy even in its late stage.
