Miosis refers to excessive contraction (shrinking) of the pupil in your eye. It is also known as cataract.
The main symptom is when the pupil in your eye becomes so large that there is a noticeable darkening around the edge of your iris. Miosis can also happen on the side of the iris. If it affects just one eye, then it is also known as cataract. Another term for miosis is pinpoint pupils.
Miosis is a very common disease and there are many causes
One such cause is an illness which affects the iris of the eye. Another cause is a tumor which moves in the bone around the iris and the lens.
Cataract and miosis are both relatively rare diseases which affect the iris of the eye but both can result in blindness. Cataract is a condition which results from damage to the lens. Miosis is caused by an infection that affects the blood vessels around the iris of the eye. Infections such as a bacterial or fungal infection will result in a reduction in the levels of blood and oxygen flowing to the iris.
When you have miosis, the normal flow of blood to the iris of the eye is reduced. When this happens, your pupil will contract or narrow and when the pupil is closed, light entering your eye will be refracted in such a way that it appears like a cataract or even a spider's web.
Symptoms of miosis include:
- Because miosis has no cure, it is important to visit a doctor as soon as possible if you suspect that you are suffering from cataracts or an eye infection. Once diagnosed, it is very important to see an eye specialist so that proper treatment can begin. Miosis is a very treatable eye disorder that can be controlled with surgery, laser surgery and/or lenses.
- Vision problems such as cataracts or myriads are very serious and they should not be taken lightly. It is important to keep an eye check-up to ensure that the vision in your eyes is good and if anything should be noticed, a doctor should be consulted as soon as possible. If you notice that your vision is getting worse, contact an eye specialist immediately.
Miosis may not be diagnosed right away
However, your doctor can take a sample of fluid from around the iris and examine it under the microscope in order to see if the miosis is present. If it is not present, then it is important to seek the advice of an eye specialist. This is because if the eye is infected, your vision will worsen and you may need to see an eye specialist sooner than you might otherwise.
Miosis is also commonly found in older people, so if you see any loss in vision or if it seems that you are losing your peripheral vision, this may be an indication that your iris is causing vision loss. or your vision is becoming blurred.
There are some treatments available to help you with the problem of miosis. If your vision has been affected, there are various ways in which to treat it.
Laser surgery is an option if the only solution is surgery. You may get the procedure done through the use of a laser which will destroy the bacteria which is infecting the eye and will remove it. It is also possible to use lasers to destroy the nerve which is responsible for vision loss.
Cataract surgery is another option for those who need to treat their vision. Cataract surgery is performed in order to reduce the amount of lenses or to correct cataract damage that may occur in the eye.
