Glaucoma

Glaucoma slowly damages the nerve that carries pictures from your eye to your brain. Early care protects the sight you still have.

Fluid flows through the pupil to the drainage angle; when the angle clogs, a pressure gauge climbs and presses on the optic nerve at the back; when drainage is restored the pressure settles.Eye pressureFluid leaves through the drainage angle

At a glance

  • What we watch

    Pressure

    Eye pressure is measured and recorded at each visit.

  • Usual start

    Drops first

    Most people begin with daily eye drops.

  • If drops are not enough

    Surgery

    Trabeculectomy opens a new drainage path.

  • Follow-up

    For life

    Glaucoma needs regular checks for many years.

Understanding glaucoma

Your eye makes a clear fluid all the time. It drains out through a tiny channel. In glaucoma (say: glaw-KOH-muh) the fluid does not drain well, pressure builds up, and the optic nerve slowly gets damaged.

Why it is called the silent thief

Most glaucoma gives no pain and no warning. You lose side vision first, so you may not notice until much is lost. Damage that has happened usually cannot be brought back. That is why regular checks matter, especially if someone in your family has glaucoma, you are over 40, you have diabetes, or you use steroid medicines.

What we do

Dr. Kumar measures your eye pressure, looks at the optic nerve and checks your side vision. The aim is to bring the pressure down and keep the nerve safe. Treatment cannot undo damage already done, but it can stop it getting worse.

Drops, then surgery if needed

Most people start with eye drops every day. Missing drops lets pressure rise again, so use them as advised. If drops cannot keep the pressure low enough, Dr. Kumar may advise surgery called trabeculectomy, which makes a new path for the fluid to leave the eye.

Honest risks

  • Drops: stinging, red eyes, dry eyes. Some can affect breathing or heart rate, so tell us about asthma or heart problems.
  • Surgery: low pressure, a shallow eye, infection, bleeding, or the new path scarring over so pressure rises again.
  • Cataract can form sooner after glaucoma surgery.
  • Call us at once if: you have sudden severe eye pain with headache, nausea or vomiting, red eye and halos around lights. This can be angle-closure glaucoma, an emergency that needs treatment within hours.

Glaucoma narrows vision like a tunnel. Treatment aims to stop this getting worse. Lost sight usually cannot be brought back.

Questions about glaucoma

Can glaucoma be cured?

No. Glaucoma can be controlled, not cured. Treatment protects the sight you have by keeping pressure under control. You will need check-ups for life.

Will I go blind?

Most people who use their treatment and attend check-ups keep useful sight for life. Without treatment glaucoma can cause serious loss. Early care gives the best chance.

What if I forget my drops?

Put the drop in when you remember, then carry on as usual. Do not double up. Tell Dr. Kumar if forgetting happens often so he can plan around it.

Why do I need so many pressure checks?

Eye pressure goes up and down. Regular readings show whether your treatment is working. The visual field test shows if the side vision is changing.

Is glaucoma surgery painful?

The eye is numbed, so you should feel little or no pain. Some soreness and redness in the days after is common. Dr. Kumar will tell you what to expect.

Your eyes deserve one doctor who knows them.
