Abstract

Purpose: Evaluate the retinal vascular lesions associated with diabetes. Methods: This study included two groups: Normal mice and streptozotocin induced diabetic mice. Retinal trypsin digest was performed to assess acellular capillarries and pericyte loss. Moreover, retinal vascular permeability was analyzed following FITC-dextran injection in retinal whole mounts. Results: The number of acellular capillaries and pericyte loss increased significantly in diabetic mice group. Furthermore, diabetic mice also showed an increase in retinal vascular permeability. Conclusion: HG promote retinal vascular cell loss and excess permeability in diabetic retinopathy.
