Optical Coherence Tomography (OCT)
An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. At Summit Eye Center, our optometrists use the OCT-A.
The OCT-A is non-invasive and employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye. The exam takes about 10 minutes.
A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to a CT scan of the eye. It works using light without radiation and is essential for early diagnosis of glaucoma, macular degeneration, and diabetic retinal disease. Additionally, the OCT-A scans the retina as well as retinal vessels, which provide important diagnostic information.
With an OCT-A scan, the eye doctor is provided with color-coded, cross-sectional images of the retina. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment, and diabetic retinopathy.
Interestingly enough, there is an OCT-A on the space station that is used for the astronauts' eye exams.
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 driver's license 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 computerized 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.
No "Air Puff Test"
We use the most advanced and least invasive technology to take pressure readings.
iCare tonometers are based on unique, patented rebound technology, in which a very light and small probe is used to make momentary contact with the cornea. The quick and painless measurement is barely noticed by the patient and any anesthesia or inconvenient air puffs are not needed at all. Icare technology has been proven accurate and reliable by several clinical studies. iCare Tonometers provide easy and intra-ocular pressure measurement.
