Purpose: To study the relation between posterior vitreous detachment (PVD) and progression of diabetic retinopathy (DR), based on our observation that proliferative DR is rare in patients with complete PVD. Methods: The medical records of 403 patients with diabetes were reviewed for the relation between progressive DR and the status of PVD and HbA(1c) over 3 years. PVD was classified into none, complete PVD with collapse, complete PVD without collapse, partial PVD with a thickened posterior vitreous cortex, and partial PVD without a thickened posterior vitreous cortex. DR was classified into none, simple, pre-proliferative, or proliferative. When it became more extensive or when laser treatment or vitreous surgery was performed, the DR was considered progressive. Results: Progression of DR over 3 years occurred in 128/ 292 (43.8%) eyes with no PVD, 0/14 (0%) eyes with complete PVD with collapse, 2/8 (25%) eyes with complete PVD without collapse, 15/15 (100%) eyes with partial PVD with a thickened posterior vitreous cortex, and 19/74 (25.7%) eyes with partial PVD without a thickened posterior vitreous cortex. Progression of DR occurred significantly more frequently in eyes with partial PVD with a thickened posterior vitreous cortex compared to eyes with complete PVD with collapse (p < 0. 0001). HbA(1c), did not differ significantly between these two groups (6.9 +/- 0.9 % and 7.5 +/- 0.9 %, respectively; p = 0. 14), although HbA(1c) was significantly higher (p = 0.04) in patients with progressive DR (78 +/- 1.8%) than in patients without progressive DR (7.5 +/- 1.5%). Conclusion: Complete PVD is a strong negative risk factor for DR. The PVD status in patients with diabetes should be evaluated.
