Cataracts can arise as an effect of exposure to various types of radiation. X-rays, one form of ionizing radiation, may damage the DNA of lens cells. [21] Ultraviolet light, specifically UVB, has also been shown to cause cataracts, and some evidence indicates sunglasses worn at an early age can slow its development in later life. [22]
Lens induced glaucomas or Lens related glaucomas are either open-angle or closed-angle glaucomas that can occur due to a neglected advanced cataract (cloudiness of the lens) or a dislocated lens. It is a type of secondary glaucoma. The angle-closure glaucoma can be caused by a swollen or dislocated lens.
In an effort to understand the cause of cataracts—beyond the normal wear-and-tear of aging, smoking, and exposure to UV rays, all of which can damage a lens’ fiber cells—researchers are ...
Phacomorphic glaucoma is an eye disease that can occur due to a neglected advanced cataract.In this, the mature cataractous lens cause secondary angle closure glaucoma.The presence of an asymmetric mature cataractous lens, shallow or closed anterior chamber angle, raised intraocular pressure (IOP) and other typical signs and symptoms of angle-closure glaucoma in the eye may lead to a diagnosis ...
Fuchs heterochromic iridocyclitis (FHI) is a chronic unilateral uveitis appearing with the triad of heterochromia, predisposition to cataract and glaucoma, and keratitic precipitates on the posterior corneal surface. Patients are often asymptomatic and the disease is often discovered through investigation of the cause of the heterochromia or ...
As the light waves enter the eye, they excite electrons that can cause harm to the cells in the eye, but they can cause oxidative damage that may lead to macular degeneration or cataracts. Lutein and zeaxanthin bind to the electron free radical and are reduced rendering the electron safe.
Cataracts cause the lens of the eye to become cloudy over time, but if they are left untreated, they can lead to complete blindness. While cataracts are unable to spread from one eye to another ...
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.
