Glaucoma is an eye condition where the optic nerve (which connects our eye to our brain), is damaged, resulting in a loss of vision. Often, glaucoma is asymptomatic. The person affected may not feel any pain as the changes inside the eye are gradual. Therefore, people suffering from glaucoma may lose vision even without them knowing it.
Glaucoma can be treated with eye drops or surgery. Treatment aims to control the condition and minimise future damage. Early diagnosis is important because any damage to the eyes cannot be reversed.
