Glaucoma assessment and treatment

Tests and treatment aim to protect the sight that remains. Regular follow-up matters.

What glaucoma does

Glaucoma slowly damages the optic nerve, usually through raised eye pressure. Lost sight does not come back, so treatment lowers the pressure to protect what you have.

Open-angle glaucoma

The drainage channel works poorly and pressure rises slowly, with no pain. Side vision fades first, so regular eye exams are how it is found.

Angle-closure glaucoma

The iris blocks the drainage channel, slowly or as a sudden attack with severe pain, redness, blur and halos.

A sudden painful red eye with blurred vision is an emergency. Seek care the same day.

How it is found

Eye pressure: Measured at almost every visit. Raised pressure is the strongest known risk factor.
Gonioscopy: A mirrored lens on the eye lets the doctor see whether the drainage angle is open or closed.
Optic nerve scan: OCT measures the nerve fibres around the optic disc and compares them over time.
Visual field: Maps blind spots in your side vision, the effect of nerve damage on what you see.

How it is treated

Treatment lowers eye pressure. It does not reverse damage already done. Your clinician discusses the options after examining your eyes.

Eye drops: The least invasive option, used every day, often for life. They can sting.
Laser trabeculoplasty: A gentle laser helps fluid drain, so fewer drops may be needed.
Laser iridotomy: A tiny opening in the iris that treats or prevents angle closure.
Drainage implants: Small stents or tubes that give fluid a new way out.
Filtering surgery: A new drainage path when drops and laser are not enough. Needs careful aftercare.

Long-term monitoring

Glaucoma is lifelong, so field tests and nerve scans are repeated and compared over the years.
