Mobile Eye Doctor Specialist on Glaucoma : The Things You Need to Know

There are lots of people who are not aware that they already have glaucoma because of lack of information about the condition. To make sure you don’t have this kind of eye problem, it is best to have your eye checked by a Mobile Eye Doctor. This article includes information about glaucoma and its possible causes.

eye doctorGlaucoma is an eye disorder that normally have few or no symptoms and may eventually cause damage to the optic nerve that transport information from the eye to the brain. Most of the time, glaucoma is associated with higher pressure in the eye. If uncontrolled or untreated, the condition may lead to minor loss of vision and eventually may result to blindness. Glaucoma is known to be the second leading cause of blindness all over the world.

Symptoms of Glaucoma

Glaucoma is also known as the silent thief of sight, because it does not have any symptoms until loss of vision occurs. For this reason, the condition most of the time progresses undetected until the optic nerve has been damaged irreversibly, with varying degrees of losing vision permanently.

Some of the symptoms that may occur suddenly with acute angle-closure glaucoma are blurry vision, intense eye pain, vomiting, halos around lights, and nausea. If you have these symptoms, it is best that you visit a Mobile Eye Doctor immediately so they can recommend you the steps to be taken to prevent loss of vision.

The Connection Between Glaucoma and Sleep Apnea

Recently, a study has been conducted to investigate on the possible link between OSAS or obstructive sleep apnea syndrome and NTG – a less understood type of glaucoma where harm to the optic nerve occurs even without the high eye pressure.

Some of the risk factors for NTG or normal-tension glaucoma include autoimmune disorders, low blood pressure, and abnormal blood flow to the eye, other blood and vascular diseases. But the real cause of this kind of glaucoma is not clear.

The study involves 24 individuals with NTG and 24 age and sex matched healthy controls. All were subjected to polysomnography (PSG) overnight, which is a standard examination for obstructive sleep apnea. The study showed that 41.7% of those with NTG had obstructive sleep apnea syndrome, compared with 12.5% of the controls.

Glaucoma Can Be Worsened if your Sleep on One Side

A study conducted in South Korea tested the sleeping habits of individuals with glaucoma, and discovered that those who sleep on one side were more likely to sleep with the affected eye facing forward. Based on research the position raises the eye’s internal pressure and may hasten the deterioration of the eye. The optic nerve is usually damaged in glaucoma due to increased intraocular pressure, which may cause tunnel vision and lead to blindness.

The study also includes comparison of the sleeping habits with patients with glaucoma with elevated intraocular pressure with those with normal pressure. Around 66% of the patients with NTG preferred to sleep with the worst eye downward, and 71% of the patient with HTG slept in that manner.

While the results will not prove that sleeping position on one side will worsen glaucoma, the researchers believe that it has a link between the preferred sleeping position and the asymmetric visual field loss between the eyes.

How to Prevent Glaucoma?

The Mobile Eye Doctor can give you advice on how to reduce your risk for glaucoma. Based on European study, exercise can help prevent glaucoma for some people.

A study in the U.K. showed that regular exercise can lower the occurrence of low ocular perfusion pressure (OPP), an essential risk factor for glaucoma. The result showed that participants who are into moderate physical exercise approximately 15 years before the study was conducted had a 25% reduced risk of low OPP that might result to glaucoma.

A Mobile Eye Doctor advices his patients to maintain an active lifestyle to reduce the risk of having glaucoma and other serious health problems.
