Your sight is beyond precious. If someone told you that you could slowly go blind from an undetectable condition, what would you do?
Testing For Glaucoma
- Tonometry tests the most important factor in diagnosing glaucoma- eye pressure. The test involves puffing a small amount of air into your eye and measuring the resistance. Eye pressure that exceeds a certain threshold is cause for concern. Some people develop glaucoma even though their eye pressure is “normal”.
- Ophthalmoscopy refers to the common “dilated eye exam” in which your eye doctor applies special eye drops to enlarge your pupils. This allows your doctor to look in the eye easily, thanks to a magnifying tool.
- Pachymetry helps determine your corneal thickness. Corneal thickness can disrupt the readings from the eye pressure exam. This is something that your eye doctor will take into consideration.
- Gonioscopy measures the drainage angle in your eye. High eye pressure is due to the angle at which the cornea meets the iris. This may not allow eye fluid to drain efficiently. Open-angle glaucoma is the most common form of glaucoma. Angle-closure glaucoma is far more dangerous than open-angle glaucoma. This form of glaucoma is actually quite painful and can quickly damage your vision.
- Perimetry measures your peripheral vision. This tells the doctor if you have already lost sight. To test your peripheral vision, you will perform a test where you tell the doctor when you see a moving light. This is performed while you are looking straight ahead.
