Glaucoma

Glaucoma is a common eye disease that affects more than 2% of the population over 45 years of age.

In France, it is estimated that about 1 million people are affected. This frequency justifies that the eye pressure is measured regularly during an eye examination.

It is recommended to consult a specialist every two years (from the age of 45) for these measurements.

In developed countries, glaucoma is the leading cause of absolute blindness. Other common causes of vision loss are age-related macular degeneration and cataracts. These two diseases are not related to glaucoma, but can occur in glaucoma patients.

There are two major forms of glaucoma:

1. Open-angle glaucoma – the most common form.
2. Glaucoma due to occlusion of the chamber angle.

Glaucoma is caused by an increase in eye pressure, which damages the optic nerve (which sends visual information to the brain) and the visual field (range of vision).

Open-angle glaucoma is related to the gradual occlusion of the drainage system, the trabecula. This phenomenon is gradual because the patient does not feel the slow increase in eye pressure.

Acute glaucoma, also known as angle closure glaucoma, occurs suddenly. It is caused by the sudden closure of the iris against the drainage system. It is accompanied by intense pain and loss of vision. This is an urgent ophthalmologic emergency.

In addition, there are also very rare glaucomas that occur from birth, so-called congenital glaucomas. Their treatment is surgical from the start.

Finally, glaucoma can occur after another eye disease, such as inflammation or trauma.

Réponse à @nadia 💝🌈🏴‍☠️ le laser SLT est une forme de laser utilisée pour diminuer la pression intra-oculaire et permettre d’éviter une fluctuation au cours de la journée de la pression intra-oculaire chez les patients atteints de glaucome à angle ouvert ou d’hypertension oculaire sans glaucome associé. #ophtalmologie #hypermetropie #glaucome #slt #myopie

La tension oculaire, ou pression intraoculaire, ne provoque pas toujours de symptômes visibles, surtout si elle est légèrement élevée. Cependant, si elle devient trop haute, comme dans un glaucome aigu, vous pourriez ressentir des douleurs oculaires, une sensation de pression, une vision floue, des halos autour des lumières, des maux de tête, ou même des nausées. Une tension trop basse, plus rare, peut causer une vision déformée ou une gêne. Souvent, ces signes apparaissent tard, donc un dépistage régulier est essentiel pour détecter un problème tôt. Si vous ressentez ces symptômes, consultez rapidement un ophtalmologue pour éviter des complications comme une perte de vision. En résumé, une tension oculaire anormale peut causer douleurs, vision floue ou halos, mais elle est souvent silencieuse au début.
