This study aims to compare the retinal perfusion between diabetic and non-diabetic patients with Optical Coherence Tomography（OCT） Angiography after cataract surgery, to thoroughly evaluate the retinal state of diabetics after surgery, and to find out the relationship between postoperative complications occurred in retina and diabetes.
In this study, we perform a completely comparison of retina state characteristic including the foveal avascular zone(FAZ),perifovea vessel density,parafovea vessel density,macular thickness,perifovea thickness,parafovea thickness in superficial and deep layers of retina with OCT Angiography after cataract surgery,and analysis on the differences of EGF,IFN-γ,IL-10,IL-12,IL-1β,IL-6,IL-8,IP-10,MCP-1,VEGF in aqueous humor before surgery between diabetic and non-diabetic patients and to explore the potential correlations between postoperative complications occurred in retina and diabetes.
