The retina receives its blood supply from all, except:
Posterior ciliary aery
Central retinal aery
Retinal aeries
Plexus of Zinn and Haller aeries
D i.e. Plexus of Zinn and Haller aeries The retina has dual blood supply, the choroidal circulation & central retinal aerial circulation. Uveal tract (choroids) is supplied by posterior ciliary aeries (long & sho) and anterior ciliary aeriesQ. Posterior ciliary aeries do not supply retina directly, (but indirectly). Plexus of Zinn supply the optic disc (lamina cribrosa)(2)
