We were intrigued to analyze donor eyes of two individuals without retinopathy even after 40 years of type 2 diabetes mellitus. Targeted molecular factors associated with angiogenesis and the key antioxidant enzymes in retinal tissue were analyzed. Accordingly PEDF, Adiponectin and Paraoxonase 2 showed augmented mRNA expression in both the retina with no significant change in VEGF expression. Vitreous showed increased PEDF protein in donor 1 and Adiponectin in donor 2 with no change in VEGF protein. This study highlights the profile of specific molecular factors that contribute to the non-development of diabetic retinopathy changes in these individuals.
