A cataract is an opacity that develops in the crystalline lens of the eye. [9] The word cataract literally means, "curtain of water" or "waterfall" as rapidly running water turns white, so the term may have been used metaphorically to describe the similar appearance between mature ocular opacities and water fall.
Approximately 50% of all congenital cataract cases may have a genetic cause which is quite heterogeneous. It is known that different mutations in the same gene can cause similar cataract patterns, while the highly variable morphologies of cataracts within some families suggest that the same mutation in a single gene can lead to different ...
Cross-sectional view, showing the position of the human lens Ultrasound scan of a unilateral cataract seen in a fetus at twenty weeks of pregnancy. Cataracts may be partial or complete, stationary or progressive, hard or soft. Histologically, the main types of age-related cataracts are nuclear sclerosis, cortical, and posterior subcapsular. [41]
Pierre Robin sequence [a] (/ p j ɛər r ɔː ˈ b æ̃ /; [3] abbreviated PRS) is a congenital defect observed in humans which is characterized by facial abnormalities.The three main features are micrognathia (abnormally small mandible), which causes glossoptosis (downwardly displaced or retracted tongue), which in turn causes breathing problems due to obstruction of the upper airway.

Childhood cataracts are hereditary in 8.3% to 25% of cases. [4] Of which, 75% of cases are inherited in an autosomal dominant fashion. [4] The diagnosis of childhood cataracts are associated with other eye abnormalities in 27% of cases and associated with systemic abnormalities/findings in 22% of cases. [4]
Isolation of the rubella virus by nasal, blood, throat, urine, or cerebrospinal fluid specimens Clinical definition is characterized by findings in the following categories: Cataracts/congenital glaucoma, congenital heart disease (most commonly, patent ductus arteriosus or peripheral pulmonary artery stenosis), hearing impairment, pigmentary ...
Cataracts: An often age-related condition that leads to gradual vision loss secondary to clouding of the lens. Examination may reveal opacification of the lens and often an absent or blunted red reflex. Dilated fundus exam allows for examination of more peripheral cataracts, as well as evaluating candidacy for cataract surgery. [9] [12]
