These types of cataracts tend to progress. A posterior subcapsular cataract often interferes with your reading vision reduces your vision in bright light and causes glare or halos around lights at night. A posterior subcapsular cataract starts as a small opaque area that usually forms near the back of the lens right in the path of light.
Cataract formation and cataract surgery in people and dogs have many similarities but dogs experience more postoperative anterior uveitis. Cataracts are an opacity of the lens or its capsule and should be differentiated from the minor lens imperfections in young dogs seen on slit lamp biomicroscopy and the normal increase in nuclear density nuclear sclerosis that occurs in older animals. This is when the nucleus of the lens actually hardens within the eye.
There are different types of cataracts including the nuclear sclerotic cataract. A cataract is the clouding of the eye s lens due to protein buildup in the body that leads to blurry vision and a loss of sight if not treated. Nuclear sclerosis is very common in humans.
Nuclear sclerosis refers to cloudiness hardening and yellowing of the central region of the lens in the eye called the nucleus. Nuclear sclerosis is the most common type of cataract and involves the central or nuclear part of the lens. The main types of age related cataracts are nuclear sclerosis cortical and posterior subcapsular.
Cataracts may be partial or complete stationary or progressive or hard or soft. In some cases the distinctions are so subtle they can confound veterinary assessment. Because cataracts and nuclear sclerosis can appear similar on casual observation owners sometimes suspect cataracts in pets with the latter.
While nuclear sclerosis affects both eyes equally and simultaneously cataracts may be uni or bilateral. Cataract is the clouding of the natural intraocular crystalline lens which focuses on. Nuclear sclerotic cortical and posterior subcapsular.
There are three main types of age related cataracts.
Posterior subcapsular cataract vs nuclear sclerosis. These 3 types of cataracts cover 99 of the cataracts that you will see in clinic. Nuclear sclerosis ns cortical spoking cs and posterior subcapsular psc. Each cataract subtype is graded depending upon its severity by who criteria. Posterior subcapsular cataracts psc are opacities located in the most posterior cortical layer directly under the lens capsule.
This type of cataract tends to occur in younger patients than cortical or nuclear sclerotic cataracts. Progression is variable but tends to occur more rapidly than in nuclear sclerosis. Also called a nuclear sclerotic cataract this is the kind doctors see most. Anyone who lives long enough usually ends up with one.
