| arteria centralis retinae | A branch of the ophthalmic artery which penetrates the optic nerve 1 cm behind the eye to enter the eye at the optic papilla in the retina; it divides into superior and inferior temporal and nasal branches. Synonym: arteria centralis retinae, arteria retinae centralis, Zinn's artery. (05 Mar 2000) |
| arteria retinae centralis | A branch of the ophthalmic artery which penetrates the optic nerve 1 cm behind the eye to enter the eye at the optic papilla in the retina; it divides into superior and inferior temporal and nasal branches. Synonym: arteria centralis retinae, arteria retinae centralis, Zinn's artery. (05 Mar 2000) |
| arteriola medialis retinae | An arteriole supplying the part of the retina between the optic disk and the macula. Synonym: arteriola medialis retinae. (05 Mar 2000) |
| arteriola nasalis retinae inferior | The branch of the central artery of the retina that supplies the lower medial, or nasal, part of the retina. Synonym: arteriola nasalis retinae inferior. (05 Mar 2000) |
| arteriola nasalis retinae superior | The branch of the central artery of the retina that passes to the upper medial, or nasal, part of the retina. Synonym: arteriola nasalis retinae superior. (05 Mar 2000) |
| arteriola temporalis retinae inferior | The branch of the central artery of the retina that passes laterally below the macula to supply the lower lateral or temporal part of the retina. Synonym: arteriola temporalis retinae inferior. (05 Mar 2000) |
| arteriola temporalis retinae superior | The branch of the central artery of the retina that passes laterally above the macula to supply the upper lateral or temporal part of the retina. Synonym: arteriola temporalis retinae superior. (05 Mar 2000) |
| macula retinae | An oval area of the sensory retina, 3 by 5 mm, temporal to the optic disk corresponding to the posterior pole of the eye; at its centre is the central fovea, which contains only retinal cones. Synonym: area centralis, macula lutea, macular area, punctum luteum, Soemmerring's spot, yellow spot. (05 Mar 2000) |
| vasa sanguinea retinae | The blood vasculature of the retina, including the branches and tributaries of the central retinal artery and vein, respectively, and the vascular circle of the optic nerve. Synonym: vasa sanguinea retinae. (05 Mar 2000) |
| vena centralis retinae | Formed by union of the retinal veins and accompanies the artery of the same name in the optic nerve. Synonym: vena centralis retinae. (05 Mar 2000) |
