Glaucoma in the eye is a common eye condition that can be treated, but is most effective if caught in the early stages. When you have glaucoma, your eyes are filled with fluid that is continually being produced and then drained. If the fluid doesn’t drain away properly, then the pressure on the back of the eye builds up, causing nerve damage which leads to glaucoma. This damage might also occur if the fluid drainage and pressure are normal, but the nerves are weak.
Some groups of people are statistically more likely to suffer from glaucoma:
There are two types of glaucoma- chronic and acute. The most common form of glaucoma is chronic glaucoma which typically has no early warning signs. It develops slowly and sometimes without noticeable sight loss for many years, and this is why it is important that you have regular eye examinations, especially as you get older. Some people, however, find that their vision worsens in one eye, eventually leading to tunnel vision, as the centre of vision is the last part to be affected.
Acute glaucoma is less common and can occur suddenly when there is complete blockage of the fluid. As it happens very quickly, it is usually painful and may induce blurred vision, rainbow-coloured halos around bright lights, headaches, nausea and vomiting.
Treatment for chronic glaucoma is extremely effective when the condition is caught in the early stages. Eye drops are the most common treatment and work by reducing the amount of fluid in the eye and improving drainage. Tablets, laser treatment and surgery may also be recommended, especially if the condition is more advanced.
Acute glaucoma is serious and requires immediate treatment in the hospital. Drugs will be given to reduce the pressure and any pain, and laser treatment or minor surgery will usually be required. The treatment is painless and treating both eyes at the same time is often recommended to stop the condition from developing in the other eye.
