Your prescription for corrective lenses
Your doctor will ask you to look at an eye chart through a device called a phoroptor. The phoroptor contains different lenses. It will help determine the best eyeglass or contact lens prescription for you.
Your pupils
Your doctor may check how your pupils respond to light by shining a bright beam of light into your eye. Pupils usually respond by getting smaller. If your pupils widen or don’t respond, this may reveal an underlying problem.
Your side vision
Loss of side vision (peripheral vision) may be a symptom of glaucoma. This test can find eye problems you aren’t aware of because you can lose side vision without noticing.
Your eye movement
A test called ocular motility evaluates the movement of your eyes. Your ophthalmologist looks to see if your eyes are aligned. They also check that your eye muscles are working properly.
Your eye pressure
Eye pressure testing, called tonometry, measures the pressure within your eye (intraocular eye pressure, or IOP). Elevated IOP is one sign of glaucoma. The test may involve a quick puff of air onto the eye or gently applying a pressure-sensitive tip near or against your eye. Your ophthalmologist may use numbing eye drops for this test for your comfort.
