A pterygium of the eye (pl.: pterygia or pterygiums, also called surfer's eye) is a pinkish, roughly triangular tissue growth of the conjunctiva onto the cornea of the eye. [2] It typically starts on the cornea near the nose. [ 3 ]
Pterygium (eye) or surfer's eye, a growth on the cornea of the eye. Pterygium colli or webbed neck, a congenital skin fold of the neck down to the shoulders. Pterygium inversum unguis or ventral pterygium, adherence of the distal portion of the nailbed to the ventral surface of the nail plate. Pterygium unguis or dorsal pterygium, scarring ...

Axenfeld–Rieger syndrome is a rare autosomal dominant [2] disorder, which affects the development of the teeth, eyes, and abdominal region. [3]Axenfeld–Rieger syndrome is part of the so-called iridocorneal or anterior segment dysgenesis syndromes, [4] which were formerly known as anterior segment cleavage syndromes, anterior chamber segmentation syndromes or mesodermal dysgenesis.
Pellucid marginal degeneration, a bilateral, noninflammatory disorder, characterized by a peripheral band of thinning of the inferior cornea. [4] Posterior keratoconus, a rare condition, usually congenital, which causes a nonprogressive thinning of the inner surface of the cornea, while the curvature of the anterior surface remains normal.
Commonest is an autosomal recessive form, which is present at birth, but nonprogressive. Nystagmus is seen in association with this form. Another is an autosomal dominant form that occurs within the first few years of life. This form is progressive, but nystagmus is not seen. Deafness and CHED are seen in Harboyan syndrome. The histologic ...
It is to be distinguished clinically from a pterygium, which is a wedge shaped area of fibrosis that may grow onto the cornea.) A pinguecula usually does not cause any symptoms. It is most common in tropical climates and there is a direct correlation with UV exposure.
