Abstract |
We compared the structural and functional corneal endothelial changes between patients with non-proliferative retinopathy and age-matched nondiabetic patients after phacoemulsification with posterior chamber lens implantation. Endothelial cell density was calculated preoperatively, and postoperative 4, 8 weeks by specular microscopy. Fluorophotometry to check corneal endothelial barrier function was underwent preoperatively and at postoperative 4 days. Preoperatively, no significant difference in corneal endothelial cell density and corneal endothelial permeability coefficient was noted between diabetic patients and age-matched non-diabetic patients. But the mean increase of corneal endothelial permeability coefficient at 4 days after surgery was 118.13% in diabetic patients and 61.88% in nondiabetic patients (P<0.05). The mean endothelial cell loss at 4 and 8 weeks after surgery were 10. 29%, 12.55% in diabetic patients and 7.05%, 9.39% in non-diabetic patients.(P<0.05) |
