Glaucoma is a complexity that is caused by excessive pressure of the fluid in the eye. It is a state where the optic nerve, which carries signals from the eye to the brain, gets infected due to intensive pressure. Inside of a human eye contains fluid that constantly flows into and drains out of the eye. If the Trabecular Mesh work is the drainage mechanism of the eye gets blocked, the fluid starts accumulating inside the eye. The optic nerve is the primary nerve of the eye that send signals to the brain, if, got damaged, could result in significant loss of vision.
The human eye can be divided into two segments: the anterior chamber and the posterior chamber. The anterior chamber is in front of the lens, the space between the cornea and natural lens is filled with aqueous humor fluid, and the posterior chamber stays behind the lens. As long as the process of aqueous humor fluid production in the anterior chamber and draining out of the eye is proportionate, your eyes are normal, or there is no sign of glaucoma. However, if they’re a small change in the production or drainage system occurs, it could lead to increased intraocular pressure. Wide-angle (Chronic Open Angle) and narrow-angle (Acute Angle Closure Glaucoma) are the two types of glaucoma that can lead to increased intraocular pressure.
Primary open-angle or Chronic open-angle glaucoma (COAG) is the most common type of glaucoma occurs when the aqueous humor fluid become clogged. This blockage gradually increases pressure within the eye. There are neither any signs or symptoms nor pain occurs. So, an individual is usually unaware of these changes, and damages are occurring.
Acute Angle Closure GlaucomaAcute Angle-Closure Glaucoma occurs when eye pressure builds up rapidly, and it can be shown in those individuals who have narrow anterior chamber angles. In such cases, aqueous fluid behind the iris cannot pass through the pupil. Hence, it pushes the iris forward and prevents the fluid drainage through the angle. Those suffering from acute angle-closure glaucoma may experience blurred vision, deep pain behind the eye, halos around lights, vomiting, and nausea.
Signs and Symptoms of GlaucomaAs an individual cannot feel any pain, or there will be no signs or symptoms of Glaucoma, it is always safe to do eye check-up annually to ensure your eyes are healthy and fit. As we all know, glaucoma can enter our life anytime without the slightest knowledge. With this, fully vision loss or blindness can happen anytime if glaucoma resides untreated. Once you approach an ophthalmologist, he/she would check your eye pressure to make sure you don’t have any indication of glaucoma. However, if one notices the following symptoms, then there can be risks of glaucoma:
High pressure behind the eye may signals glaucoma. But It doesn’t alone indicate that you have glaucoma. Here in our hospital, we put many kinds of information all together to find out the risk of developing this disease. Some of the important factors from them are:
With early detection, you could reduce the impact on the optic nerve. Once any damage to the eye occurs, it can be reversed. The best way to tackle such disease is through regular eye check-ups.
Glaucoma can be treated with medication or surgery. The medication includes eye drops to reduce the secretion of aqueous humor fluid. Surgery helps to open up the blocks for proper drainage of the fluid, thus keeping your eyes healthy and normal. This surgery can be performed by Trabeculectomy (TRAB) or using LASER.
Glaucoma is an eye disease that secretly damages the optic nerve (that transmits information from the eye to the brain), causing permanent vision loss. Most commonly, this damage occurs when the internal fluid pressure of the eye rises too high. And, it happens due to inadequate drainage of fluid normally produced in your eyes.
Ocular hypertension is another high eye pressure term where the intraocular pressure (IOP) is higher than normal. In ocular hypertension, the optic nerve doesn’t get damaged, and there is no chance of vision loss. However, ocular hypertension is a risk factor for glaucoma which should be treated immediately.
The two most common types of glaucoma tests during a routine eye test are non-contact tonometry (NCT) and applanation tonometry. In NCT, a machine emits a quick puff of air towards the surface of the eye. And, that air touches your cornea. This air puff test is considered as a screening measurement to determine the pressure within your eye.
Whether you are an American, African, Indian, diabetic, or having family members diagnosed with glaucoma disease, and your age is more than 60, then the chances of getting glaucoma are higher in you than others. Making it much more common in elderly people or older adults within the age range of 40 to 60, but glaucoma can occur at any age. In actual fact, two rare branches of glaucoma named as congenital glaucoma and infantile glaucoma can exist from birth.
Where only 5% of Europeans are diagnosed with glaucoma and go blind, in India, at least 12 million people are affected by glaucoma and approx. 1.2 million people go blind from the disease. Hence, 9/10 of cases of this disease remain undiagnosed. How terrible it is!
No, a patient can’t go through LASIK, if he/ she has glaucoma. It is because, in LASIK surgery, a suction device is used to create a corneal flap on the eye. But another type of vision correction surgery called PRK is available which doesn’t require a suction device.
Though glaucoma can be treated, vision loss from it cannot be recovered. Thus, it is essential to do routine eye check-up to discover glaucoma at its early stage and begin its treatment before any significant loss has occurred.
