Systemic and Ocular Hemodynamic Risk Factors in Glaucoma

Figure 2

Different vascular support system between macula and peripapillary area. (1) Macula is only supplied only by the single-layered perifoveal capillary arcade. (2) Peripapillary area had double-layered vascular support system which connects between radial peripapillary capillaries (RPC) in retinal nerve fiber layer and capillaries in ganglion cell layer. MOPP, mean ocular perfusion pressure (adapted from [73]).
