Glaucoma is one type of eye disease with indirect symptoms, which gradually causes longer vision to decrease so that eventually the eyes will become blind. This is because the fluid channel that comes out of the eyeball is blocked so that the eyeball pressure will increase which in turn will suppress the eye nerves that are behind the eyeball which eventually the eye nerve does not get blood flow so that the eye nerve will die.
The main cause of glaucoma is increased eyeball pressure above 20mmHg, other causes are hypertension and diabetes mellitus. Although rare, it can also be caused by unstable emotions, migraines, narrowing of arteries and others. The pressure of the eyeball above normal, which will continuously damage the visual nerve, but often not realized by the patient, because the damage little by little. Therefore it is necessary to check eye pressure, if it is 40 years and over, especially if there is a history of glaucoma in the family. To reduce the pressure of the eye, you can use drops / medication to drink, laser or surgery.
