iCare Tonometers for easy, accurate and patient-friendly intraocular pressure measurement. iCare tonometers are based on unique, patented rebound technology, in which a very light and small probe is used to make a momentary contact with the cornea. No specialized skills for its use the quick and painless measurement is barely noticed by the patient and any anesthesia or inconvenient air puffs are not needed at all.
Non-contact tonometry (or air-puff tonometry) uses a rapid air pulse to flatten the cornea. Corneal applanation is detected via an electro-optical system. Intraocular pressure is estimated by detecting the force of the air jet at the instance of applanation.
The auto-refractor is a digital refractor that works much the same way as the old-fashioned phoropter. The big difference is that, instead of the doctor manually clicking through, asking you to decide for yourself which lens is best.
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 only 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 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.
A fundus, or retinal camera, A fundus, or retinal camera, is a specialized microscope with an attached camera designed to photograph the central retina, optic disc and macula.
The resulting photograph is a high resolution magnified image which can help to assess for eye conditions including glaucoma, diabetic retinopathy, macular degeneration, optic nerve disease, and many others. This picture also gives us a baseline to compare the state of your eye health in the future.
Optical Coherence Tomography Scan
We use cutting-edge digital imaging technology to assess your eyes. Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. Your retinal Images will be stored electronically. This gives the eye doctor a permanent record of the condition and state of your retina.
An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.
A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to an 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.
With an OCT scan, doctors are 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.
An OCT scan is a noninvasive, painless test. It is performed in about 10 minutes right in our office. Feel free to contact our office to inquire about an OCT at your next appointment.
