While cyanopsia can be briefly disorienting, it rarely interferes significantly with daily activities. Symptoms usually resolve on their own within hours to weeks, depending on the cause. Cyanopsia after cataract surgery diminishes as the eye adapts, while medication-induced cyanopsia resolves once the medication's effects wear off.
Cataracts can be developed through old age, diseases or trauma to the eye. [5] Some animals that are prone to the development of cataracts are dogs, elephants, horses, pandas and seals. Cataracts are less common in cats [6] in comparison to dogs, where it is fairly common. Just like with humans, cataract extraction surgery can be performed on ...
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 ...
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'.
Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [1] it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness.
Attachment to the cornea can cause small corneal opacities, while attachment to the lens can cause small cataracts. Using topical atropine to dilate the pupil may help break down PPMs. In dogs, PPM is inherited in the Basenji but can occur in other breeds such as the Pembroke Welsh Corgi, Chow Chow, Mastiff, and English Cocker Spaniel.
Children with this condition are born with congenital cataract (or they have an early-onset cataract which presents before two months of life). These cataracts are caused by hypomyelination, which is the body's inability of producing nerve fiber myelin. [3] Development is normal for kids with this condition until the age of 1 year of life, when ...
Irvine–Gass syndrome, pseudophakic cystoid macular edema or postcataract CME is one of the most common causes of visual loss after cataract surgery. [1] [2] The syndrome is named in honor of S. Rodman Irvine [3] [4] and J. Donald M. Gass. [5] The incidence is more common in older types of cataract surgery, where postcataract CME could occur ...
