Symptoms of glaucoma are usually not noticeable in its early stages and people are urged to do regular eye check ups. One common symptom causes is loss of peripheral vision or reduced clarity of colours. Ophthalmologists and optometrists diagnose glaucoma on the basis of intraocular pressure, visual field tests and also by the shape or appearance of an optic nerve.

The main risk factors for developing glaucoma is positive family history of having the disease, and it also more prevalent in people of African descent and people already suffering from Myopia (shot sightedness).

Free eye tests will be done preferably on people above the age of 40, as they are at a greater risk of developing glaucoma.
