Glaucoma - General Information

Glaucoma is often associated with increased intraocular pressure but may also exists when the pressure is normal. And vice-versa the patient may have high intraocular pressure but without a glaucoma. The intraocular pressure is the one that keeps the round shape of the eye by a slight pressure of the fluid secreted in the eye .

If the removal of these liquids is limited, the pressure will increase and this can damage the optic nerve that transmits images from the eye to the brain. The glaucoma starts with the loss of peripheral vision and if not properly treated it can lead to blindness.

This illness is very common around the world, being the main cause of blindness in both eyes. Many of the ones that have glaucoma may not yet know because at the beginning this condition is asymptomatic.

The main causes of glaucoma are the causes that may raise the intraocular pressure, and intraocular pressure may increase in two important cases: the intraocular fluid is produced in excessive amounts or the discharge of the intraocular fluid is affected .

Glaucoma may appear in everyone but there are a number of factors that lead to increased risk of glaucoma, like : diabetes and vascular disease, family history (cases of glaucoma in the family), severe myopia, ageing, eye injury, use of steroids, hyperopia (when someone sees better at distance than close).



For early detection of glaucoma is important to know its symptoms and the patient’s subjective sensations. In the case of increased intraocular pressure, can be observed following symptoms: sensation of heaviness and tension; it begins to be harder to see at dusk, blurred vision, the appearance of a so called “net” before the eyes. significant pain around the eye.

In the case of angle-closure glaucoma, the patients often present bouts The symptoms of this bouts are : strong pain in the eyes, headache, significant increase in intraocular pressure. The bouts of angle-closure glaucoma is often confused with a migraine, tooth pain, acute stomach disease, meningitis, influenza, because the patient experience headaches, nausea, general weakness without mentioning any eye problems.

In the case of congenital glaucoma beside the increased intraocular pressure it is also detected an increased size of the eyeball. When a patient suffers from primary angle closure glaucoma, the eye may become red and the patient may see haloes around lights.

Glaucoma is not a contagious disease. Usually, glaucoma occurs in both eyes, but not simultaneously: in the second eye can occur over several months or years . Vision lost because of glaucoma can not be recovered!
