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.
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 ...
Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'.
The polyol metabolic pathway. [6]Cells use glucose for energy.This normally occurs by phosphorylation from the enzyme hexokinase. However, if large amounts of glucose are present (as in diabetes mellitus), hexokinase becomes saturated and the excess glucose enters the polyol pathway when aldose reductase reduces it to sorbitol.
The blood–ocular barrier is a barrier created by endothelium of capillaries of the retina and iris, ciliary epithelium and retinal pigment epithelium. [1] It is a physical barrier between the local blood vessels and most parts of the eye itself, and stops many substances including drugs from traveling across it. [2]
This may occur in the event of posterior capsule rupture, zonular dehiscence, [Note 8] a dropped nucleus [Note 9] with a nuclear fragment more than half the size of the cataract, [14] problematic capsulorhexis with a hard cataract, [14] or a very dense cataract where the heat developed by phacoemulsification is likely to cause permanent damage ...
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 ...
A subconjunctival hemorrhage can often occur without any obvious cause or harm to the eye. A strong enough sneeze or cough can cause a blood vessel in the eye to burst. Hyphema is a result of blunt or penetrating trauma to the orbit that increases intraocular pressure, causing tears in the vessels of the ciliary body and iris.
