Glaucoma is a group of eye diseases that primarily damage the optic nerve, which is crucial for vision. This damage is often associated with elevated intraocular pressure (IOP), although glaucoma can occur even when eye pressure is normal. The condition is typically progressive and can lead to irreversible vision loss if not diagnosed and treated promptly.
There are several types of glaucoma, with the two most common being:
1. **Primary Open-Angle Glaucoma (POAG)**: This is the most common form and occurs when the drainage canals in the eye become less efficient, leading to a gradual increase in intraocular pressure. POAG usually develops slowly and often without noticeable symptoms until significant vision loss has occurred.
2. **Angle-Closure Glaucoma**: This type occurs when the iris blocks the drainage angle in the eye, preventing fluid from exiting. This can happen suddenly (acute angle-closure glaucoma), causing severe pain, nausea, and rapid vision loss, or it can develop more gradually (chronic angle-closure glaucoma).
Symptoms of glaucoma may include:
- Gradual loss of peripheral vision (tunnel vision)
- Blurred vision
- Halos around lights
- Eye pain
- Headaches
- Nausea and vomiting (in acute cases)
Risk factors for developing glaucoma include age, family history of the disease, certain medical conditions (such as diabetes), prolonged use of corticosteroids, and elevated intraocular pressure.
Diagnosis typically involves a comprehensive eye exam that includes measuring IOP, evaluating the optic nerve, and assessing peripheral vision.
Treatment options vary according to the type and severity of glaucoma and may include:
- Medications (usually in the form of eye drops) to lower intraocular pressure
- Laser treatments to improve fluid drainage
- Surgical procedures to create a new drainage pathway
Early detection and consistent management are crucial for preserving vision in individuals with glaucoma. Regular eye exams, especially for those at higher risk, are important for monitoring eye health.
