- Intraocular pressure
- Risk factors
Because glaucoma can lead to impaired vision before its symptoms become apparent, it is helpful to have an idea about the factors that increase the risk of developing this disorder.
- Elevated intraocular pressure
People with elevated intraocular pressure (IOP), the probability of glaucoma is above average, although not everyone with high IOP will develop the disease.
At risk are usually related to people older than 60 years, although the chance of developing angle-closure glaucoma increases after 40 years. However, some ethnic groups, such as people of African descent, the risk of glaucoma increases significantly earlier age, and they should undergo regular examinations by an ophthalmologist with approximately 20-30 years.
Do black people over the age of 40 years, the risk of developing glaucoma is much higher than in Caucasians of the same age. They also have the greatest potential permanent loss of vision due to glaucoma. Representatives of Asian nations increased likelihood of developing acute angle-closure glaucoma
Angle-closure glaucoma - possibly severe course of the disease
- A family history of glaucoma
If your family history of glaucoma, you are at risk for developing this disease. Experts believe that these patients may have a genetic predisposition to the disease glaucoma.
Some diseases, both active and deferred earlier, increase the likelihood of glaucoma; These include diabetes, heart disease

and hypothyroidism. Serious damage to the eye may cause increase in IOP and consequently lead to the development of glaucoma. The same effects can be and some eye diseases. Some surgical procedures can become triggers glaucoma. In addition, the risk of developing glaucoma is elevated in myopia and hyperopia people. Finally, long-term use of corticosteroids, particularly - eyedrops containing these substances also increases the likelihood that the individual will become ill glaucoma.
If glaucoma is not treated, it will lead to a gradual loss of vision that usually goes through the following steps:
- The appearance of blind spots in the peripheral vision;
- Tunnel vision;
- Total blindness.
Do the glasses glaucoma?
Points do not apply to treatment of glaucoma. If you wore glasses before, once you have been diagnosed with glaucoma, you should continue to wear them, as before. If glaucoma will lead to a further deterioration of view, you will write new glasses, but they will not be able to slow the progression of the disease - they're just not designed for that.
At the same time, patients with glaucoma are advised to wear sunglasses - they also do not stop the progression of the disease, but they can be used to avoid the development of cataracts

Therefore, in sunny weather it is always recommended to wear sunglasses - this is useful even for those who are not sick glaucoma.
