GlaucomaGlaucoma is a type of disease that results from damage to the optic nerve of the eye. This can cause vision loss which can lead to blindness. Glaucoma can be prevented if detected early and treated in a timely manner to avoid significant vision loss and eye damage. There are different types of this disorder, including open-angle glaucoma which includes low tension and high tension. Pressure in the eye builds up due to a slow release of fluids flowing 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, it will be damaged and lead to vision loss. Different people experience different levels of pressure that can potentially lead to glaucoma. Another very rare type of glaucoma is angle-closure glaucoma, which occurs when the drainage channels close and intraocular pressure increases. This type of glaucoma should receive medical help immediately. Usually, there are no noticeable early signs or symptoms of glaucoma and can develop slowly over many years. Most people feel fine and normal if they have open-angle glaucoma and see no significant changes in their vision and acuity for many years. Some of the symptoms are blurred vision, rainbow circles around bright lights, headache, nausea or vomiting, and sudden loss of vision. Due to the low detection rate of open-angle glaucoma, it is very important to see an ophthalmologist regularly. There is a clear difference between closed-angle glaucoma and open-angle glaucoma. Angle-closure glaucoma appears much more quickly and is much more serious. There are several environmental and genetic causes and risks...... middle of paper ...... one day you will still go blind. An unfortunate feature of this condition is that some symptoms can persist for years without the person knowing, 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. Currently, there is no cure for glaucoma and vision loss cannot be reversed. More efforts should be made to educate the public about glaucoma and its symptoms so that people are more aware and can take the necessary precautions to seek medical attention.
