Primary closed-angle glaucoma (GLCC) is characterized by age-related variation in the degree of iridocorneal angle closure and its sequelae, with patients in the first 3 decades of life showing a normal eye exam, whereas older patients progressively show more evidence of angle closure and glaucomatous damage, including optic nerve head changes and visual field defects (Suri et al., 2018). [from OMIM]

Knobloch syndrome-1 (KNO1) is an autosomal recessive developmental disorder primarily characterized by typical eye abnormalities, including high myopia, cataracts, dislocated lens, vitreoretinal degeneration, and retinal detachment, with occipital skull defects, which can range from occipital encephalocele to occult cutis aplasia (summary by Aldahmesh et al., 2011). Genetic Heterogeneity of Knobloch Syndrome KNO2 (618458) is caused by mutation in the PAK2 gene (605022) on chromosome 3q29. [from OMIM]
