The Importance of Early Detection and Treatment of Glaucoma

See more
Glaucoma is a common eye disease that affects the optic nerve which connects the back of the eye to the brain. There are many different types of glaucoma, but the common thread amongst all of them is that it causes damage to the optic nerve which can lead to severe vision loss if not treated. Many types of glaucoma are caused by high pressure in the eyes. This disease can occur at any age but is most commonly developed in older adults. One of the leading causes of blindness in the population age 60 and older is glaucoma.

It is extremely important to have routine eye exams in order to be screened for glaucoma, as it often goes undetected for a long time, until it progresses to a more severe disease. Vision loss from glaucoma cannot be regained and therefore early detection is essential. There are treatment plans which can slow down or even prevent vision loss if diagnosed early enough.

It’s important to make sure that you go for regular routine eye exams in order to be monitored by your eye doctor. If you have a history of glaucoma in your family or if you are forty years or older then you will be screened for this eye disease more frequently.

If you experience eye pain, blurred vision and severe headaches, please book an appointment immediately with your eye doctor. If there isn’t an appointment available right away you will be guided to go to your local emergency room. It’s possible that you have an acute form of a serious type of glaucoma which needs to be treated immediately.

Symptoms

The symptoms greatly depend on the type of glaucoma and the stage of the disease. Two main types of glaucoma are open angle glaucoma and closed angle glaucoma. The latter has a specific form of the disease known as acute closed angle glaucoma which is considered to be an eye emergency. If you are experiencing any symptoms of the acute form, please book an immediate appointment with your eye doctor. If there isn’t a time slot available right away, please don’t delay and go to the nearest emergency room.

Open Angle Glaucoma

The main symptom is changes in your visual field. Some people may notice patches of blind spots in the central or peripheral vision which occurs in both eyes. If the damage to the visual field advances, it can cause tunnel vision which means that the person can only see in the narrow center of the visual field, but not the periphery.
