The Topcon TRC-NW8 provides amazing high definition images of the inside your eye.
As part of a medical evaluation of your eye, your doctor will review the health of your optic nerve, retina, and blood vessels. Photodocumention is very important in the management of systemic diseases such as diabetes and hypertension, as well as ocular side effects of many common medications. Eye diseases like macular degeneration and glaucoma can be properly monitored to help maximize our most precious gift of sight.
Tonometers are used to measure Intraocular Pressure (IOP) as a routine part of diagnosing and managing the 2nd leading cause of blindness in the world, glaucoma. However, traditional methods of tonometry, including the Goldmann Applanation Tonometer, are significantly affected by corneal properties, compromising the accuracy of their IOP measurements. The 7CR incorporates the patented bi-directional applanation technology, first used in the revolutionary Reichert Ocular Response Analyzer (ORA), to quantify the biomechanical properties of the cornea. This in turn permits the determination of Corneal Compensated Intraocular Pressure (IOPcc). IOPcc provides clinicians with a better understanding of patient tonometry values, enhancing their ability to make critical diagnosis and treatment decisions.
Your visual field is how wide of an area your eye can see when you focus on a central point. (peripheral vision) Visual field testing can determine if you have blind spots (called scotoma) in your vision, and where they are. This test is very important in diagnosing and following Glaucoma. It helps us to know if there is any side (peripheral) vision loss due to the disease. It is also used to determine if vision is limited due to eyelid problems, such as ptosis (drooping of the eyelids.) The test takes anywhere from 10-15 minutes to complete.
OCT is a non-invasive imaging test that uses light waves to take cross-section pictures of your retina and/or optic nerve. OCT is useful in diagnosing many eye conditions, including:
Macula hole, pucker, and edema (swelling.)
Age-Related Macular Degeneration
The OCT is both diagnostic and a guidance tool in the treatment for diseases such as Glaucoma and diseases of the retina. The test takes about 5-7 minutes to complete.
Fundus photography uses high-resolution flash photography, along with a microscope, to photograph the fundus (the back of the eye.) The fundus camera allows us to view the retina, retinal vasculature, optic disc, macula, and posterior pole. This test is useful in diagnosing and managing conditions such as:
Age-Related Macular Degeneration
The test takes less than 5 minutes to complete and does require dilation of the pupils.
The ERG measures the electrical response of the light-sensitive cells in your eyes (rods and cones.) These cells are what form the retina. The test measures the function of the retinal ganglion cells to determine if they are healthy, damaged but still salvageable, or dead. During the test, a technician will attach sensory pads to your forehead and skin under the eyes. The test is performed one eye at a time and consists of looking at patterns on a computer screen, and the computer records the eyes’ response to the images.
ERG is used to determine if you have any disease in the retina. Follow the link below to learn more about Diopsys ERG, and watch a video of the test in action.
