What diagnostic procedures detects glaucoma?

Answer 1

A Good optometrist will check for glaucoma in several ways. Family History Intra-ocular pressure: Non-contact tonometry or contact tonometry (better) Appearance of your optic nerve (preferably with a retinal photograph) Your visual field using automated perimetry, which maybe repeated several times. Other machines can be used which aim to measure the thickness of your nerve fibre layer through indirect measurements which can be useful for tracking nerve changes and glaucoma progression but cannot be used solely for diagnosis. It takes a combination of all these measures to diagnose glacuoma

Answer 2

There are a few tests to diagnose glaucoma. The most common is to approach your optometrist for a test. This test involves checking the eye pressures(this is different from one's blood pressure). Glaucoma is a condition whereby the eye pressure is elevated. The eye pressure check is quick and not painful as many optometrists use what is commonly known as a non-contact tonometer. This machine checks the eye pressure using a puff of air.

Answer 3

The main symptom of glaucoma is vision loss, especially loss of peripheral vision. However, half of all people who experience loss of vision caused by glaucoma are not aware they have the disease. By the time they notice loss of vision, the eye damage is severe.

Answer 4

This is a common question that I answer as an eye doctor regularly. Glaucoma is best evaluated by an optometrist or ophthalmologist. A physician assistant, nurse, and all other physicians are generally not equipped to accurately diagnose glaucoma. In most cases glaucoma is asymptomatic, meaning a patient will not experience a noticeably change in vision or eye discomfort despite the fact that they have glaucoma. Two forms of glaucoma are acute cases or chronic cases.

The most dangerous acute cases of glaucoma usually involve angle closure. This will cause high levels of pain, discomfort, redness of the eyes, and blurred vision that would be immediately noticeable. When the patient comes in to see an optometrist or ophthalmologist, they will be able to detect acute angle closure by using a slip lamp and a special gonio lens. In addition, your eye physician will check your eye pressure, or intraocular pressure, with tonometry. The very high eye pressure ready, for instance 40 and above, is cause for emergent concern and needs to be treated immediately. The mechanism behind an acute angle closure is that there is a special area of the eye that serves to drain fluid from the eye. If that drain is clogged, fluid is blocked from escaping yet the eye will continue to pump more fluid in. The more fluid that accumulates inside the eye the higher the intraocular pressure becomes. The worst case scenario of acute angle closure glaucoma is permanent vision loss.

Chronic glaucoma happens slowly over time. Chronic open angle glaucoma is the most common form of glaucoma in the United States. While your primary care physician or allied health professional may have hints to a case of acute angle closure glaucoma, it is nearly impossible for them to detect a chronic case of glaucoma. Chronic open angle glaucoma is detected by a dilated eye examination from your optometrist and ophthalmologist who evaluate your optic nerve health as well as check your eye pressure. In addition, your eye doctor will have you tested for a visual field to see if you test within the normal range for someone your age since glaucoma's major symptom is peripheral vision loss. However, before peripheral vision loss is detected, your eye doctor has sophisticated imaging technology that can scan multiple layers of your optic nerve and retina to detect if you have glaucoma or not. Based on the combined outcomes of how you do on these imaging devices, your eye pressure, visual field results, openness of the drain out of your eyes, corneal thickness, and how your optic nerve appears to your eye physician is how glaucoma is diagnosed and detected the majority of the time.
