Introduction. Glaucoma is a disease that affects the optic nerve within the eye. This nerve is responsible for sending information from the eyes to the brain and is crucial for proper vision. Typically, glaucoma results from extensive high pressure inside of the eye. As time passes, this pressure can erode the nerve tissue, which may lead to loss of vision. However, when caught early, complete blindness may be prevented. Glaucoma has several causes and doctors can help plan different treatment plans based on each individual patient’s health and lifestyle.
Information. The main symptom of glaucoma is gradual vision loss. Glaucoma is the second most common cause of blindness around the world, making it important to monitor vision, having comprehensive eye exams yearly. Glaucoma is most common in older people, as eyes aged over 60 are more susceptible to problems and complications. African Americans are also more likely to develop the disease than other ethnicities. Usually, glaucoma is not categorized as an emergency. There is a certain type of glaucoma, though, known as ‘narrow-angle glaucoma’, that does constitute a medical emergency. Symptoms of this type of glaucoma include nausea, severe eye pain, redness in the eye(s), seeing colored rings around lights, sudden blurred vision, and vomiting.
