Regular examinations are the key to maintaining healthy eyes and comfortable vision. Many eye problems are not accompanied by blurred vision. Patients with early stages of glaucoma, cataracts and macular degeneration often have no symptoms. Children with vision problems frequently don’t complain because they’ve always seen that way. Eye exams can also detect signs of systemic diseases such as diabetes, hypertension, and multiple sclerosis as well as ocular side effects from drug therapies such as plaquenil and tamoxifem.
Our exams involve much more than a prescription for glasses. Vision is a very complex process that requires many structures to function properly in order to obtain clear, comfortable vision. A variety of tests may be necessary to assess the health and proper function of the eyes including:
- Medical and Ocular History– identifies your current visual complaints and potential risk for eye problems.
- Visual Acuity– tests your current vision at distance and near.
- Color Vision– tests your ability to see color normally. Color Vision defects are usually inherited but can be acquired in ocular disease.
- Depth perception– tests your ability to combine the image from each eye into a single 3 dimensional view.
- Pupillary Reaction– tests neurological function
- Eye Co-ordination/Binocularity– assesses how well your eyes move together
- Peripheral Vision – tests your general ability to see objects outside of the spot where you are directly looking.
- Refraction– measures the refractive state of the eye to help determine the need for glasses
- Accommodative Response– measures your ability to change focus from distance to near.
- Keratometry– measures the curvature of the cornea to fit and monitor CL wear, assess refractive surgery candidates and monitor corneal disease.
- Autorefraction– measures the refractive state of the eye with infrared light.
- Tonometry – measures the pressure of the fluid of the eye- IOP. Don’t worry, we traded in the dreaded “eye-puff” test more than a decade ago!
- Ocular Health Examination– using various lenses and instruments, we examine the structures of the eye including the lids, cornea, lens and retina to check for signs of ocular and systemic diseases such as dry eye, cataracts, glauoma, macular degeneration, diabetes and hypertension.
If medical problems are discovered, we can provide further testing and medical eye care.
Additional Testing Available:
- Threshold Visual Fields- measures the sensitivity of your peripheral vision for use in glaucoma management and identification of neurological or vascular problems.
- OCT allows us to view high resolution cross-sections of the eye (almost like an MRI) and measure individual layers of the eye to help diagnose and monitor various eye diseases including macular degeneration, glaucoma and diabetes.
- Anterior Segment Photography- documents conditions on the front portion of the eye including the iris, sclera, cornea, conjunctiva and lids.
- Fundus Photography- documents conditions in the posterior part of the eye behind the iris including: the retina, macula, optic nerve and vitreous. It also allows stereo photography of the optic nerve for use in glaucoma monitoring.
- Pachymetry- ultrasonic measurement of corneal thickness for glaucoma suspects, refractive surgery patients and patients with corneal diseases.
