Corneal Mapping at Patterson Eye Clinic

Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision.

The three-dimensional map is therefore a valuable aid to the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses. A development of keratoscopy, corneal topography extends the measurement range from the four points a few millimeters apart that is offered by keratometry to a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.

Visual Field Testing

A visual field test measures how much 'side' vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating.

Each eye is tested separately and the entire test takes 15-45 minutes. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks.

Normally the test is carried out by a computerised machine, called a Humphrey. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.

Dear valued Patterson Eye Clinic patients:

We are open for normal business hours as of May 11, 2020. Essential and preventative eye care, as well as optical services, will resume immediately. Many patients are overdue for eye care. We will make every effort to schedule your examination promptly while also continuing to use safety and social distancing measures to help reduce the spread of COVID-19.

Our top priority is to provide a safe, clinical environment for our patients and team. All patients, doctors, and staff are screened via temperature checks and oxygen level testing upon entering the clinic. Our staff and doctors are required to wear personal protective equipment while administrating care. We are also requesting that all patients wear a mask when visiting the clinic. All rooms, work surfaces, and instruments are thoroughly cleaned and disinfected between patients. We have changed procedures to reduce time in the office, including adjusting patient scheduling to maximize social distancing. Telehealth care and curbside pick-ups will also continue to still be available.

We are grateful for your patience during this difficult time.

Sincerely,

Peter Nardone, O.D.

Laurel Loukx, O.D.
