GlaucomaGlaucoma is a type of disease that is the result of damage to the optic nerve in the eye. This can result in vision loss which can lead to blindness. Glaucoma can be prevented if detected early and treated within a reasonable time to avoid significant vision loss and eye damage. There are several types of this disorder including open-angle glaucoma which includes low and high tension. Pressure in the eye increases due to the slow release of fluid into and out of the anterior chamber of the eye. It builds up near the optic nerve and creates pressure and tension. When pressure builds up near the optic nerve, the optic nerve will be damaged and cause vision loss. Different people have different levels of pressure that could potentially lead to glaucoma. Another very rare type of glaucoma is closed-angle glaucoma, which is when the drainage channels close and the intraocular pressure increases. This type of glaucoma should receive medical attention immediately. There are usually no obvious early signs and symptoms of glaucoma and it may develop slowly over many years. Most people feel well and normal if they have open-angle glaucoma and do not see any significant changes in vision and acuity for many years. Some of the symptoms are blurred vision, rainbow-colored circles around bright lights, head pain, nausea or vomiting, and sudden loss of vision. Due to the limited number of findings in open-angle glaucoma, it is very important to consult an ophthalmologist regularly. There is a clear difference between closed-angle and open-angle glaucoma. Closed-angle glaucoma comes on much faster and is much more serious. There are several environmental and genetic causes and the risk… half the paper… will eventually go blind anyway. An unpleasant feature of the disorder is that there are symptoms that can persist for years without the person realizing it and which can lead to blood loss. In the United States alone, more than 100,000 people suffer from permanent vision loss due to glaucoma, and 60 million worldwide. There is currently no cure for glaucoma and vision loss cannot be reversed. More efforts should be made to inform the public about glaucoma and its symptoms, so that people are more aware and can take the necessary precautions to seek medical attention.
