\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)\...

A rare genetic inflammatory corneal disorder characterized by anterior stromal corneal opacification and vascularization of the peripheral cornea with potential central progression and subsequent reduction in visual acuity. Variable features include abnormalities of the iris, such as stromal defects and ectropion uveae, as well as foveal hypoplasia.	Finding site	True	Corneal structure	Inferred relationship	Some	1
X-linked corneal dermoid (X-CND) is an exceedingly rare, benign, congenital, corneal tumor characterized by bilateral opacification of the cornea with superficial grayish layers and irregular raised whitish plaques, as well as fine blood vessels covering the central cornea, and intact peripheral corneal borders. No other ocular or systemic abnormality is noted. The pattern of inheritance described in the affected family is consistent with X-linked transmission.

Ophthalmomandibulomelic dysplasia is characterized by complete blindness due to corneal opacities, difficult mastication due to temporomandibular fusion and anomalies of the arms.	Finding site	False	Corneal structure	Inferred relationship	Some	4
Microcephaly-microcornea syndrome, Seemanova type is characterized by microcephaly and brachycephaly, eye anomalies (microphthalmia, microcornea, congenital cataract), hypogenitalism, severe intellectual deficit, growth retardation and progressive spasticity. It has been described in two patients (a male and his sister's son). Both patients also presented with facial dysmorphism, including upslanting palpebral fissures, epicanthal folds, highly arched palate, microstomia, and retrognathia. This syndrome is transmitted as an X-linked trait.	Finding site	False	Corneal structure	Inferred relationship	Some	3

A rare, genetic, neurological disorder characterized by the association of slowly progressive spinocerebellar degeneration and corneal dystrophy, manifesting with bilateral corneal opacities (which lead to severe visual impairment), mild intellectual disability, ataxia, gait disturbances, and tremor. Additional manifestations include facial dysmorphism (i.e. triangular face, ptosis, low-set, posteriorly angulated ears, and micrognathia), as well as mild upper motor neuron involvement with hypertonia, lower limb hyperreflexia and extensor plantar responses. There have been no further descriptions in the literature since 1985.	Finding site	True	Corneal structure	Inferred relationship	Some	4
