What it is
Glaucoma damages the optic nerve, often in association with raised pressure inside the eye. It usually affects side vision first and progresses without pain or obvious symptoms, so it is frequently detected only on examination. Vision already lost cannot be recovered; treatment aims to slow further damage.
When you might need it
- Age above 40, when periodic screening is generally advised
- A parent or sibling diagnosed with glaucoma
- High spectacle power, diabetes, or long-term steroid use
- You have been told your eye pressure is high
What happens during your visit
Eye pressure is measured, the optic nerve is examined after dilation, and where indicated visual field testing and optic nerve imaging are done. If glaucoma or a suspicion of it is found, treatment usually begins with daily eye drops, with laser or surgery considered in selected cases.
Aftercare
Drops need to be used exactly as prescribed and continued long term, even though the eyes feel normal. Regular follow-up is part of the treatment — it tracks pressure and any change in the optic nerve or visual fields.
