COMPREHENSIVE EYE EXAMS
The Benefit of Regular Eye Exams at Delaware Eye Center
Getting an eye exam is an important part of staying healthy. A comprehensive exam not only secures that your eyes themselves are healthy, but your eye doctor can also look for changes noticed when there are other health problems in the body.
Comprehensive eye exams should be performed on children around the age of 4 to screen for Amblyopia (Lazy Eye), and adults should be examined at age 40. If there are no systemic diseases that suggest otherwise, adults can be examined just once every 5 years until the age of 65, at which time, they should be examined yearly due to the higher incidence of cataract, glaucoma and macular degeneration.
What is Included in a Comprehensive Eye Exam?
A comprehensive eye exam at Delaware Eye Center is relatively simple and comfortable and shouldn't take more than 45 to 90 minutes. The exam should include checks on the following:
Your medical history. First, your eye doctor* will ask you for an assessment of your vision and your overall health. Your family's medical history, whether you wear corrective lenses or whether you are on any medication will also be of interest to your ophthalmologist or optometrist.
Your visual acuity. This is the part of an eye exam people are probably most familiar with. Your ophthalmologist or optometrist will ask you to read a standardized eye chart to determine how well you see at various distances. The test is performed on one eye at a time by covering the eye not being tested.
Your pupils. Your eye doctor may evaluate how your pupils respond to light by shining a bright beam of light through your pupils. Common pupillary reaction to this stimulus is to constrict (become smaller). If your pupils respond by dilating (widening) or there is a lack of response either way, this may indicate an underlying problem.
Your side vision. Loss of side vision is a symptom of glaucoma. Because you may lose side vision without knowing it, this test can identify eye problems that you aren't even aware of.
Your eye movement. This test, called ocular motility, evaluates the movement of your eyes. Your ophthalmologist or optometrist will want to ensure proper eye alignment and ocular muscle function. Common tests measure the eyes and their ability to move quickly in all directions and slowly track objects.
Your prescription for corrective lenses (eyeglasses or contact lenses). You will be seated and asked to view an eye chart through a device called a phoroptor, which contains different lenses. The phoroptor can help determine the best prescription for eyeglasses or contact lenses to correct any refractive error you may have, such as myopia.
Your eye pressure. This test, called tonometry, measures the pressure within your eye (intraocular eye pressure, or IOP). Elevated IOP is a 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 or optometrist may use numbing drops for this test for your comfort.
The front part of your eye. A type of microscope called a slit lamp is used to illuminate the front part of the eye, including the eyelids, cornea, iris and lens. This can reveal whether you are developing cataracts or have any scars or scratches on your cornea.
Your retina and optic nerve. Your ophthalmologist or optometrist will put drops in your eye to dilate, or widen, your eye. This will allow him or her to thoroughly examine your retina and optic nerve, located at the back of your eye, for signs of damage from disease. Your eyes might be temporarily sensitive to light for a few hours after they are dilated.
Your ophthalmologist or optometrist may suggest additional testing to further examine your eye using specialized imaging techniques such as OCT, topography or fundus photos. These tests can be crucial in diagnosing a disease in its early stages and allow your eye doctor to detect abnormalities in the back of the eye, on the eye's surface or inside the eye.
Each part of the comprehensive eye exam provides important information about the health of your eyes. Make sure that you are getting a complete examination as part of your commitment to your overall health.
