Since this month is National Glaucoma Awareness Month, this post is intended to emphasize the importance of regular screening for this vision threatening disease. Glaucoma is a class of eye disorders that cause damage to the eye's optic nerve, which can be a precursor to a permanent loss of vision. When uncontrolled, glaucoma often initially causes vision loss in the periphery of the field of vision and then moves to total blindness. Glaucoma is considered to be the primary reason for preventable loss of vision and according to estimates, over sixty million individuals worldwide are afflicted with it.
The primary source of glaucoma is considered to be elevated pressure in the eye referred to as intraocular pressure. The elevation in pressure causes damage to the optic nerve which delivers messages to the brain. When this system doesn't function as needed, vision is affected. Regrettably, damage to the optic nerve is usually permanent.
The most dangerous thing about glaucoma is that distinct from other causes of vision loss, there are no indicators that serve as a warning until it may be too late.
It is due to this that glaucoma is known as the "sneak thief of sight." This may leave you wondering: how is it possible to safeguard against an illness which lacks any tell-tale symptoms?
Early diagnosis of the disease is crucial to effective care. While everyone may be at risk for glaucoma, particular populations have a higher risk than others. Risk factors for glaucoma may include adults over 45, anyone with family members who have had glaucoma, diabetes, or known eye problems such as elevated intraocular pressure.
There are several different kinds of glaucoma such as open-angle or closed angle glaucomas. Both eyes are usually affected, although the disease can advance more rapidly in one of the eyes.
The best way to detect glaucoma is to find a qualified optometrist. There are several diagnostic eye examinations employed to assess intraocular pressure and the risk of glaucoma. Particularly if you are 45 or older or know that you are at risk, it's important to book a routine eye examination on a yearly basis.
It is unfortunate that for the most part glaucoma cannot be prevented. Nevertheless the optic nerve damage and loss of vision may be halted by timely diagnosis and prompt treatment. Contact Alpharetta Eye Associates now, for a yearly glaucoma screening.
