  1. ORGANUM VISUS (VISUAL SYSTEM)

  2. ORGANUM VISUS (VISUAL SYSTEM) TUNICA FIBROSA BULBI - sclera: posterior 5/6 of eye - cornea: anterior 1/6 of eye Tunica • fibrosa bulbi • vasculosa bulbi • interna bulbi Sclera (diameter: 11-12 mm) lamina cribrosa sclerae fascia bulbi (Tenoni) → spatium episclerale spatium perichoroideum Cornea (diameter: 7-8 mm) facies anterior et posterior corneae limbus corneae sclerocorneal junction - sulcus sclerae - venous sinus sinus venosus sclerae (Schlemm‘s canal)

  5. CILIARY BODY (CORPUS CILIARE) plicae ciliares pars optica retinae orbiculus ciliaris corona ciliaris zonula ciliaris ora serrata processus ciliares fibrae zonulares

  6. IRIS margo pupillaris margo ciliaris facies anterior et posterior iridis m. sphincter pupillae – parasympathetic fibres - miosis m.dilatator pupillae – sympathetic fibres - mydriasis angulus iridocornealis → reticulum trabeculare

  7. cornea angulus iridocornealis- reticulum trabeculare sclera corpus ciliare nucleus fibrae zonulares (spatia zonularia) capsula

  8. TUNICA INTERNA BULBI RETINA pars optica retinae (pars ciliaris retinae, pars iridica retinae) pars caeca retinae ora serrata pars optica retinae stratum pigmenti retinae (pigmented layer) stratum neuroepitheliale (layer of rods and cones) stratum ganglionare retinae (ganglioniclayer of retina) stratum ganglionare nervi optici (ganglionic layer of optic nerve)
