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.
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] Nuclear sclerosis is the most common type of cataract, and involves the central or 'nuclear' part of the lens. This eventually becomes hard, or ...
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]
A hairy tongue may be an indication of Epstein Barr virus infection and is usually seen in those infected with human immunodeficiency virus. Other systemic diseases that can cause the tongue to form aphthous ulcers are: Crohn's disease and ulcerative colitis, Behcet's Syndrome, pemphigus vulgaris, herpes simplex, histoplasmosis, and reactive ...
Unless the individual has an impaired immune system, e.g., owing to HIV or cancer-related immune suppression, [22] recurrent infections tend to be mild in nature and may be brought on by stress, sun, menstrual periods, trauma or physical stress. [23] Mumps of the salivary glands is a viral infection of the parotid glands.
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.
