Secondary cataract: What’s also known as an “after-cataract” isn’t technically a cataract because it’s caused by cloudiness on the outside of your lens, not the inside, but the vision ...
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'.
Visual phototransduction is the sensory transduction process of the visual system by which light is detected by photoreceptor cells (rods and cones) in the vertebrate retina.A photon is absorbed by a retinal chromophore (each bound to an opsin), which initiates a signal cascade through several intermediate cells, then through the retinal ganglion cells (RGCs) comprising the optic nerve.
Caused by a foreign body, dust, sand, or grit trapped under the lens. Corneal edema Caused by decreased oxygen delivery to the tissue compressed by the lens. Usually resolved after the removal of the lenses. Discomfort upon lens removal may be seen. Neovascularization New blood vessels may form in the iris region and the limbus. This may impair ...
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 ...
Cataract surgery is the most common application of lens removal surgery, and is usually associated with lens replacement. It is used to remove the natural lens of the eye when it has developed a cataract, a cloudy area in the lens that causes visual impairment. [4] [10] Cataracts usually develop slowly and can affect one or both eyes. [4]
Eyes described as γλαυκός due to disease might have had a gray cataract in the Hippocratic era, or, in the early Common Era, the greenish pupillary hue sometimes seen in angle-closure glaucoma. [111] [112] This colour is reflected in the Chinese word for glaucoma, 青光眼 (qīngguāngyǎn), literally “cyan-light eye”.
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.
