What are the symptoms of glaucoma?
Glaucoma is a condition where increased pressure in the eye can result in loss of vision.
At first there may not be any symptoms of glaucoma, but left untreated, it causes a gradual loss of vision.
Glaucoma, or the warning signs of it, may be detected during routine eye checks.
Different types of glaucoma affect vision in different ways:
Chronic open-angle glaucoma
This slow developing type of glaucoma causes a gradual loss of peripheral vision.
Acute-angle closure glaucoma
This type of glaucoma can begin quickly causing throbbing pain and redness in the eye, headaches, blurred vision, halos appearing around lights, pupils becoming dilated, nausea and vomiting. Urgent treatment is needed to prevent permanent vision loss.
Developmental (congenital) glaucoma in infants
A child is born with this type of glaucoma, which can cause watery eyes, light sensitivity and eyelid spasms. The eyes may also look larger and cloudy and the child may squint or rub their eyes a lot. The child should be seen by a GP or optometrist as soon as possible.
Secondary and other forms of glaucoma
Symptoms will depend on the underlying condition contributing to the abnormal rise in pressure.
These include inflammation inside the eye from uveitis causing halos and light sensitivity.
Eye injuries and other eye conditions can also lead to glaucoma.
Seek medical advice if you have symptoms that may indicate glaucoma.
