Glaucoma is an eye disease responsible for a progressive and irreversible destruction of the optic nerve, most often caused by excessive pressure inside the eye.
Certain factors favor the emergence of glaucoma:
– The increase of the intraocular pressure
The pressure of the eye is between 14 and 16 mmHg in a healthy individual. Above 21 mmHg, the pressure becomes the main factor favoring glaucoma.
Other factors favoring glaucoma have been identified:
– Myopia: which makes the eye more fragile;
– Age: over 40 years old;
– Heredity: the risk of glaucoma is higher in certain families;
– High blood pressure (HTA);
– Taking corticosteroid drugs for a long time;
– Ethnicity: people of black skin and African origin are more likely to develop glaucoma.
When the disease is advanced, glaucoma can be revealed by:
– Eye pain;
– A decrease in the visual field: especially on the sides
– Very red eye with perikeratitis circle: the whole eye is red and a circle of small red vessels forms around the iris;
– Ocular pain: extremely violent, qualified as frightful;
– Rapid decrease in visual acuity: perception of colored halos, loss of vision of forms, “visual fog”;
– Nausea and vomiting: because of the visual deficit.
