Glaucoma is a disease of the eye that causes damage to the Optic Nerve which leads to progressive loss of peripheral vision. This damage is permanent, but treatment stops or slows the progression.
The eye produces fluid internally, called aqueous, which supplies nutrients inside the front of the eye. This fluid drains out through a circumferential drainage canal at the outer edge of the iris, covered by spongy tissue called trabecular meshwork.
If the aqueous production exceeds outflow, the intraocular pressure will increase and damage the sensitive retinal nerve fibres that make up the optic nerve.
There are several types of Glaucoma. The two main types are angle-closure or open-angle.
Closed-angle Glaucoma has a closed or narrow space where the iris meets the cornea limiting the drainage of aqueous into the circular canal. This results in a rise of intraocular pressure. It can develop very quickly and then require urgent attention. Laser iridotomy is a procedure to treat narrow angles. During a laser iridotomy, the light is used to create a small hole in the iris that forms your pupil which improves aqueous flow. Cataract surgery may also treat this problem.
Open-angle Glaucoma occurs when the angle where the iris meets the cornea is wide open. The drainage of aqueous is reduced in this type of Glaucoma due to increased resistance in the trabecular meshwork causing increase of intra ocular pressure (IOP). This form of Glaucoma usually develops slowly.
In normal tension glaucoma, the optic nerve becomes damaged even though eye pressure stays within normal levels.
Secondary Glaucoma occurs when there is an underlying cause for increased pressure such as inflammation or prolonged usage of steroids (cortisone). Pseudo exfoliation is the commonest cause of secondary Glaucoma, resulting from flaky material clogging the trabecular meshwork, leading to increased intra ocular pressure.
Treatment for open angle glaucoma consists of laser (SLT), eye drops and surgery.
Glaucoma is usually picked up during a routine eye test. It is more common over the age of 40 and when there is a family history of glaucoma
