What is glaucoma?
Glaucoma is a group of eye conditions that can damage the optic nerve.
Symptoms, causes and assessment
Common forms may have no early symptoms and gradually affect side vision. Eye pressure matters but one measurement is not enough; the optic nerve and visual field are assessed. Family history influences screening needs.
Care and when to seek help
Treatment aims to slow progression and may involve drops, laser or surgery. Sudden severe eye pain, redness, nausea and blurred vision can indicate an emergency form; seek help immediately.
