\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 syndromic, genetic cataract characterized by the association of congenital cataract and microcornea without any other systemic anomaly or dysmorphism. Clinical findings include a decreased corneal diameter (inferior to 10 mm) in both meridians in an otherwise normal eye, and an inherited cataract, which is mostly bilateral posterior polar with opacification in the lens periphery that progresses to form a total cataract after visual maturity has been achieved. Association with other ocular manifestations, including myopia, iris coloboma, sclerocornea and Peters anomaly may be observed.	Finding site	False	Corneal structure	Inferred relationship	Some	2
