Glaucoma is a disease of the optic nerve head. The optic nerve carries images we see from the eye to the brain. It is made up of many nerve fibres, which glaucoma damages when it strikes, causing blind spots in our vision, then narrowing of our field of vision and ultimately complete vision loss.
There could be many causes of optic nerve head failure, but majority are due to high intraocular pressure (eye pressure) and some due to poor blood supply. There are
2 major types of glaucoma, open angle or angle closure. The unique feature of this disease is that there can be absolutely no symptoms in the majority of the cases in the early stages unless it is an acute angle closure attack. By the time vision is affected, it will be too late to reverse the blindness caused by it. This is why this disease is known as “the sneak thief of sight”! You just do not realize you have this condition until it is too late.
WHICH IS WHY SCREENING FOR THIS CONDITION IS OF UTMOST IMPORTANCE, BECAUSE IF DETECTED AND TREATED EARLY, BLINDNESS IS PREVENTABLE To learn more about Glaucoma, tune in to the podcast by Stevens and Dr. Fang Seng Kheong
