What is glaucoma ?
Glaucoma is a chronic, slowly progressive disease of the eye that leads to optic nerve atrophy. Undetected and untreated glaucoma is one of the most common causes of blindness.
Frequently the most widespread forms of glaucoma are not specific symptoms and for a long time may not result in any complaints. Glaucoma usually begins in one eye, but with time, evolves in the other eye. While the disease affects only one eye, vision changes may be overlooked. Unfortunately, late diagnosed glaucoma caused vision loss is irreversible.
Glaucoma most often develops after age 40, and with age the risk increases. Therefore, the annual preventive visual inspection should be measured intraocular pressure and evaluate the possible changes in the optic nerve. In particular, attention should be paid to :
- If someone in the family has this disease;
- If there is a high degree of myopia;
- If you have high blood pressure, high cholesterol, diabetes or any other illness Or long-term steroid use.
The most common symptoms are increased intraocular pressure, but also at normal or even reduced pressure the eye pressure may cause glaucomatous optic nerve changes. However, increased eye pressure, or hypertension does not necessarily mean glaucoma. Glaucoma is diagnosed, taking into account the variations inherent in optic nerve and visual field. To diagnose glaucoma which would need treatment, your doctor will perform the following procedures :
- Measure the internal eye pressure ( tonometry ) and corneal thickness ( pachymetry ) ;
- Evaluate intraocular fluid drainage system of the eye front chamber corner ( gonioskopy ) ;
- Assess the optic nerve , so possible changes ( ophthalmoscopy and OCT) ;
- Controls side or peripheral vision ( perimetry ) .
All procedures are carried out in an outpatient setting , they are most often painless and will not affect your vision and working day of the inspection. Common investigation takes an average of one hour.

Depending on the type of glaucoma, your doctor will decide on the most appropriate treatment in order to limit further fiber optic atrophy and reduce the risk of vision impairment. Glaucoma therapy’s main task is to reduce the pressure in the eye, to restore internal liquid reflux path functionality and improve blood flow to the optic nerve. Often enough effective medical management therapy is a pressure-reducing eye drops. If they do not give a satisfactory result, your eye doctor may decide on laser treatment or if surgery is necessary. Glaucoma cannot be cured completely. With the disease you have learn to accommodate and to be constantly monitored. Reduction and control of eye pressure significantly reduces the risk of vision loss.
