Glaucoma is a medical condition which damages the optic nerve of the eye and can get worse overtime. It occurs due to the buildup of pressure in your eyes. Glaucoma is usually inherited and passed down the genes if your family member has it. Glaucoma usually destroys the nerve which aids in transmitting images to your brain. It can result to irreversible vision loss within a few years if not treated properly. If you have diabetes, you are more prone in developing glaucoma.
Glaucoma is an intricate eye condition in which the optic nerve damage may occur and it will lead to loss of vision if untreated. The two common forms of glaucoma are primary open-angle glaucoma (POAG) and acute angle-closure glaucoma (ACG). In POAG, you may not experience any symptoms until vision loss. The early symptoms of acute angle-closure glaucoma are blurred vision, severe eye pain with nausea and vomiting, sudden sight loss, the appearance of halos.
In angle-closed glaucoma which is otherwise called narrow-angle glaucoma, the patients may see an increased eye pressure that will lead to optic nerve damage. The eye pressure may occur gradually or suddenly. The symptoms of acute angle-closure glaucoma are much noticeable and the damage may occur quickly. Vision loss because of glaucoma isn't reversible with treatment and even with a medical procedure called therapy. So, immediate medical attention and regular examination are required to prevent vision loss.
Glaucoma occurs when the liquid in the eye doesn’t circulate how it should, this in turn results in extremely high pressure in your eyes. The liquid which is called aqueous humor usually starts to flow out your eyes through a channel. If this channel is blocked, the fluid starts building up resulting in Glaucoma. Factor such as inflammatory conditions, blocked blood vessels in the eye, acute eye infection, chemical injury and a blunt can cause Glaucoma. It is rare but possible in some cases. An eye surgery performed to treat another condition can also trigger Glaucoma. It can affect both the eyes.
Risk factors for Glaucoma:
At first, the specialist will dilate your pupils with eye drops. He will then check the optic nerve. A test called tonometry can be performed to keep a check on your eye pressure. A visual field test is also done to figure if your peripheral and side vision has been affected or not. Diagnoses for Glaucoma takes very less time and is also quite painless.
The glaucoma medications are intended to control as well as lower the intraocular pressure (IOP) which can harm the optic nerves that send visual data to the cerebrum. The patient is advised with glaucoma eye drops initially and it is very effective in controlling IOP. Sometimes, the ophthalmologist may put on combination glaucoma drops i.e. more than one drug to achieve the best IOP control.
Some types of glaucoma drops are Prostaglandins, beta-blockers, Alpha-adrenergic agonists, Carbonic anhydrase inhibitors, Parasympathomimetics, Epinephrine, and Hyperosmotic agents. There are a couple of ophthalmic drug stores that delivered mix eye drops that contain two distinctive anti-glaucoma prescriptions in a similar container. Depends on the eye condition and the type of glaucoma, the drug/s is advised. It is advisable to put the drops in the eyes as prescribed by the doctor.
A regular eye examination can only prevent the eyes from glaucoma damage. Since there is no known way to prevent glaucoma, significant eye loss can be prevented at the early diagnosis. In primary open-angle glaucoma, it affects the side vision first and it progresses to the central vision.
Glaucoma medicines decrease the progression of glaucoma by reducing the increased IOP. The headstand and shoulder stand positions should be avoided if you are doing yoga which will simultaneously increase the IOP. Eye injuries may lead to secondary or traumatic glaucoma. So, protecting eyes from further injuries always helps to prevent glaucoma.
