What is glaucoma? Can glaucoma lead to blindness?
Glaucoma is an eye disease that causes damage to the optic nerve, which may cause permanent visual loss. It is commonly associated with damage when the pressure of your eye rises too high. However, in some eyes, damage to the optic nerve may occur even when the eye pressure is within the normal range.
Glaucoma is one of the common causes of visual loss and blindness in adults in Hong Kong, and worldwide. The visual loss in glaucoma is not reversible. Particularly in early stages of the disease, there may not be any symptoms, and visual loss may occur without being noticed by the patient. If glaucoma is recognised at an early stage, then progression of visual loss may be halted, slowed, or prevented. Should glaucoma be diagnosed, you will generally require long-term follow-up, monitoring and/or treatment.
