Glaucoma

Glaucoma is a degenerative or progressive disease that damages the optic nerve of the eye. The optic nerve connects to the retina and is formed by many nerve fibers, like an electric cable is composed of many cables.

The optic nerve sends signals from the retina to the brain where these signals are interpreted as the images we see.

In the vast majority, glaucoma is associated with high intraocular pressure. Intraocular pressure normal values are ​​between 10 and 21 millimeters of mercury (mm Hg); Glaucoma is characterized by increased IOP above normal values. Sometimes you can find ocular hypertension at the time of the consultation, and sometimes it is normal that this tension may be elevated in other times of the day.

In cases where there are signs of glaucoma in the absence of ocular hypertension, it is very important to daily monitoring ocular pressure fluctuations in search of the same, by a pressure curve daily. There is also the Normal tension glaucoma. And age is not a determining factor.

Glaucoma is a public health problem and is currently the second leading cause of blindness in the world: an estimated 7,000 million people suffer from glaucoma. In Costa Rica, about 200,000 “Ticos” have the disease and 90% out of these, do not even know they do have this problem.
