Axial Length and Diabetic Retinopathy
The study presented by Man et al contributes to our understanding of the pathophysiology of diabetic retinopathy (DR) by demonstrating, in a large clinical study, that eyes with longer axial length are less likely to have DR or diabetic macular edema. Clinical DR is a disease of retinal capillaries characterized by leakage (edema) and rupture (hemorrhage). Vessel leakage and rupture are influenced by intravascular hydrostatic pressure (as per the Starling principle and the Laplace law) with high pressure increasing and low pressure decreasing their incidence.
