SNOMED CT Concept\Body structure (body structure)\Anatomical or acquired body structure (body structure)\Anatomical structure\...

\An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Structure of sensory organ\Eye structure\Eye proper part (body structure)\Eyeball segment structure\Posterior eyeball segment structure\Vitreous and/or retinal structures (body structure)\Retinal structure\Zone of retina\Structure of optic portion of retina\Optic disc structure

A rare genetic eye disease characterized by microcornea, coloboma of the iris and the optic disc, axial enlargement of the globe, staphyloma, and severe myopia. Additional manifestations are mild cornea plana, iridocorneal angle abnormalities with elevation of intraocular pressure, and shallow anterior chamber depth. Variable expressivity of the phenotype has been described, including unilateral or bilateral involvement, or variable extent of coloboma, among other features.	Finding site	True	Optic disc structure	Inferred relationship	Some	2
A rare genetic eye disease characterized by congenital profound excavation of the optic nerve head with diminished visual field, in the absence of elevated intraocular pressure. Many patients lack a well-formed retinal artery and have multiple radial cilioretinal arteries instead. The condition is mostly bilateral, may worsen progressively, and is often complicated by serous macular detachment with profound visual loss.	Finding site	True	Optic disc structure	Inferred relationship	Some	1
A rare congenital optic disc excavation characterised by deep fundus excavation of chorioretinal atrophy surrounding a relatively normal appearing optic disc. Retinal vasculature is normal, and retinochoroidal coloboma and glial anomalies are absent. Patients present with mostly unilateral markedly reduced visual acuity. Association with other congenital defects or systemic diseases is uncommon.	Finding site	True	Optic disc structure	Inferred relationship	Some	1

A rare inflammatory optic neuropathy characterized by recurrent episodes of idiopathic inflammation of the optic nerve head with optic disc edema associated with macular exudate in a star-shaped pattern. Patients present with acute visual loss, most typically in the form of a large central scotoma. Pain is mild or absent. Bilateral involvement is frequent and usually sequential. The interval between attacks is highly variable, ranging from months to several years. Visual loss is cumulative with each attack and often severe.

A condition where there is a noticeable difference in the cupping (or indentation) of the optic disc between the two eyes which may indicate glaucomatous optic nerve damage in the eye with the larger cup-to-disc ratio.	Finding site	True	Optic disc structure	Inferred relationship	Some	1
