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 ...
The sides of the tongue are inspected with a gloved hand holding a piece of gauze. The tongue is moved side to side and inspected; it should be pink, moist, smooth and glistening. Assessment of the ventral (bottom) surface of the tongue is done by having the patient touch the tip of their tongue against the roof of their mouth.
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]
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]
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]
Phacolytic glaucoma (PG) is a form of glaucoma which is caused due to a leaking mature or immature cataract.Inflammatory glaucoma which occurs in phacolysis is a condition which is a result of the leakage of protein within the lens into the capsule of a mature or hyper mature cataract and involves a simple procedure to be cured that is referred to as cataract extraction.
