- Stages of glaucoma - the types of disease
- Acute glaucoma and pigmentary
Because most people in early stages of glaucoma does not cause any symptoms or pain associated with elevated intraocular pressure is very important to be screened regularly by an ophthalmologist. You need to know about the stages of glaucoma, to timely detect the disease and begin treatment before it has time to cause severe vision loss.
The first, or initial stage of glaucoma
Typically, glaucoma diagnose the presence of visible damage to the optic nerve.
However, the initial stage glaucoma usually asymptomatic, with no visual problems, despite the existing damage.
Since at this stage the intraocular pressure has increased, the doctor prescribes eye drops to reduce it. As a rule, they have to be used throughout life as glaucoma can not be cured - it can only slow down its development.
The second and third stages of glaucoma
These steps are also called, respectively, moderate and far advanced. On these stages, patients have observed changes in vision. In the second stage of glaucoma is disrupted peripheral vision - it usually happens so slowly that people can for quite a long time not to notice that the vision that something is wrong.
In the third stage glaucoma, peripheral vision can be almost completely disappear. Dose, patients who take, may be increased, and in some cases may be assigned to treatment with surgical methods. After this stage may come fourth or terminal stage of glaucoma, which will be discussed separately.
Terminal glaucoma - it is the fourth, the last stage of glaucoma, which can lead to the onset of blindness. For the treatment of glaucoma, a surgical intervention is required, although this wary of both patients and doctors. Patients scares common myth that some people with end-stage glaucoma, sudden onset blindness. In fact, there is a small probability of a temporary deterioration of vision (until its total loss), while in the absence of treatment blindness occurs far more likely. AT
Racei often stops that many patients have unrealistic expectations about the outcome of the operation. On the one hand, they may be afraid that the operation would lead to blindness, but on the other - are hoping that it is almost completely restore vision.
In fact, if there is serious damage to the optic nerve can only be a partial recovery of vision.
Temporary blurred vision, which is sometimes seen in patients undergoing surgery usually resolves spontaneously, and for this to take any action is needed. In any case, terminal delay treatment of glaucoma should not, as it may cause irreparable damage to the optic nerve.
Glaucoma and cataracts
Usually in patients with glaucoma are not at increased risk of developing cataracts. Exceptions are patients with secondary glaucoma
Secondary glaucoma - against the backdrop of another disease
Caused by inflammation or trauma to the eye, as well as steroids. Some diseases, such as congenital rubella, can cause glaucoma, cataracts, and often both diseases at once. Both of these disorders are more common in older people.
Blurred vision caused by cataract (as opposed to visual impairment associated with glaucoma) is reversible. Vision can be significantly improved by using a relatively simple operation. Moreover, such an operation can change the intraocular pressure, but it is impossible to say in advance, it will fall or rise. Some patients after surgery for cataract, a sharp increase in IOP. Sometimes it is possible to normalize the pressure with medication, but in some cases required another surgery - even for treatment of an acute attack of glaucoma.
Some drugs for the treatment of glaucoma can worsen the symptoms of cataracts

- Most often they cause a significant decrease in visual acuity.
Computer and glaucoma
According to a recent study, people who spend much time at the computer, increased the likelihood of developing glaucoma. The risk is especially great in short-sighted people.
The study involved 10,000 office workers of four major Japanese companies. The average age of study participants - 43 years. They were asked about how much time they spend on the computer each day, and how long, on average, they were working at a computer in the last years.
More than 500 people from the study were found to have problems with peripheral vision, 165 of them have been identified glaucoma

. However, the actual number of patients with glaucoma may be larger, since some subjects with visual impairment have not passed all the diagnostic procedures necessary to detect glaucoma. The researchers also point out in 136 of the 165 people with glaucoma have myopia

. They suggested that the optic nerve in short-sighted people may have structural features that increase the likelihood of damage due to stress associated with prolonged work at the computer. To reduce the risk of developing glaucoma, experts recommend:
- Pauses. Every hour on the computer identifies five minutes trying to look to the side - window on the opposite wall, or somewhere else. Especially useful to look at the objects that are on you at different distances;
- Sit so that your eyes are not less than 60 cm from the screen;
- Position the computer screen slightly below eye level;
- Sit up straight.
