Hunter’s Hill Eyecare Center provides the most comprehensive eye examination you can obtain. We evaluate not only your vision, but your overall ocular health. The following tests will be performed during your visit to our office.
Visual Acuity Testing
This is the standard eye chart test which compares what you can see to what is considered normal vision. 20/20 means that you can see at 20 feet what a person with normal vision would be expected to see at the same distance. 20/40 means that you see at 20 feet what the normal eye could see at 40 feet and thus your eyesight is less than normal.
Refraction is how we come up with the final prescription numbers for your glasses or contact lenses. You will have at least three different refraction checks. The first is done by a computerized instrument called an autorefractor before you see the doctor. Later the doctor will do both an objective and subjective refraction to determine the final prescription.
Optical Coherence Tomography
OCT is a non-invasive imaging test that uses light waves to take cross-section pictures of the retina and other delicate eye structures. The test aids your doctor in the diagnosis and early detection of retinal diseases such as macular degeneration and diabetic eye disease.
Biomicroscopy and Ophthalmoscopy
These two procedures are the eye health testing part of your examination where we look at both the exposed structures such as your lids, lashes , cornea and iris and then at the inside of your eye to examine your optic nerves, blood vessels and retina. Many ocular conditions including cataracts, macular degeneration, glaucoma, diabetic retinopathy, dry eye and corneal dystrophies can be diagnosed with these procedures. Dilating drops may be required during this portion of the exam to enlarge your pupils for a more thorough examination of internal ocular structures.
One of the best ways to determine if an ocular condition or structure is changing or getting worse is to take a picture for comparison at future examinations. Our new digital imaging system can capture detailed images of lid lesions, corneal dystrophies, conjunctival abnormalities, optic nerve disease, macular degeneration, diabetic retinopathy and many other conditions. We will gladly show you and your family any abnormal findings that should be followed by digital imaging and of course give you a full explanation of the condition.
Intraocular Pressure Testing
High eye pressure is a risk factor for glaucoma. In glaucoma, the individual nerve fibers in the optic nerve die and can produce defects in the peripheral visual field that can progress to significant vision loss. In many cases this nerve damage is preceded by an elevation of the internal eye pressure. We check your pressure by first instilling an anesthetic eye drops and then lightly touching your cornea with a pressure sensing instrument. Normal pressure ranges from 10 to 21 mmHg.
In the past, eye examinations have traditionally concentrated on the clarity of central (straight ahead) vision with less emphasis on the width and sensitivity of our peripheral (side) vision. A new technology called FDT now allows us to quickly screen our patients for an abnormalities in the peripheral vision which may be indicators for glaucoma, optic nerve disease, tumors of impending vascular disease such as stroke. We strongly recommend that patients over the age of 30 have this testing performed every 3 to 5 years, especially if you have diabetes, frequent headaches, high blood pressure, nearsightedness, or family history of glaucoma.
