• An Overview of Some Common Tests for Glaucoma

    Your ophthalmologist will look at several factors when it comes to diagnosing glaucoma. Two common tests, called tonometry and ophthalmoscopy, are performed routinely during glaucoma check-ups. Here is an overview of some common tests for glaucoma.


    One component of a glaucoma diagnosis is an evaluation of the pressure within your eye ; the test that measures this is called tonometry. During this test, your eyes may be numbed with eye drops and a tonometer will be used to measure the inner pressure of your eye. This is done in one of two ways—your eye may receive a puff of air, or a small amount of pressure may be applied. Eye pressure varies between individuals, but a clear excess of pressure is a sign of glaucoma. The normal range is between 12 and 22 mm Hg.


    Another common test for glaucoma analyzes your optic nerve. Glaucoma can affect both the shape and color of your optic nerve, and the ophthalmoscopy test allows eye doctors to see if this has occurred. Your pupils will be dilated with eye drops, and then your eye doctor will use magnification to get a closer look. If your optic nerve looks normal and your intraocular pressure is within a healthy range, you should be fine. If your optic nerve appears abnormal, however, your ophthalmologist will probably conduct additional tests.


    If your eye doctor decides that you should undergo further glaucoma testing, he or she may move on to perimetry. During this test, your doctor will map out your vision using a moving light and your responses. This can help to determine whether glaucoma has damaged your visual field. If you are diagnosed with glaucoma, you will probably repeat this test at least once a year to look for any changes in your vision over time.

  • The Importance of Routine Eye Exams

    There are various different risk factors for eye problems, so it is important to have your eyes checked regularly. Children should have their eyes checked at six months of age, three years of age, and before the beginning of first grade. Adults should see an eye doctor biannually until age 60, at which point they should go annually.

    Eye exams are crucial for detecting conditions like cataracts, glaucoma, and age-related macular degeneration. If you have a family history of vision problems, you may be able to catch the issue before symptoms develop. During a routine eye exam, your eye doctor will test your eye muscle movement, your visual acuity, and the way your pupils react to light. These tests can help to ensure that you retain your eyesight as well as your general eye health throughout your life.

    If you are overdue for an eye exam, call Dr. Mark Hornfeld in NYC at (646) 681-3100. Dr. Hornfeld and his team of vision professionals provide a range of ophthalmology services, including cataract surgery, glaucoma treatment, LASIK surgery, and lens implants.
