Glaucoma

Glaucoma is a common eye disease, affecting more than 2% of the population over the age of 45.

In France, it is estimated that approximately 1 million people are affected. This high prevalence justifies regular intraocular pressure measurement during an eye examination.

It is advisable to see your specialist every two years or so (from the age of 45) to have these measurements carried out.

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

Two major forms of glaucoma exist.

These are open angle glaucoma, the most common, and angle closure glaucoma.

Glaucoma is due to an increase in eye pressure leading to damage to the optic nerve (which sends visual information to the brain) and the visual field (vision space).

Open-angle glaucoma is linked to the progressive closure of the evacuation filter, the trabecular meshwork. This phenomenon is progressive because the patient does not feel the slow increase in eye pressure.

Angle-closure glaucoma, also known as acute glaucoma, is a sudden and severe condition. It occurs when the iris quickly adheres to the drainage filter, leading to significant pain and vision loss. This is a major ophthalmologic emergency.

There are also very rare types of glaucoma that occur from birth, called congenital glaucomas. From the outset, their treatment is surgical.

Finally, glaucoma can develop as a result of another eye condition, 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.
