Preliminary Testing Procedures
Digital Retina Imaging (HD iCare). Digital retina imaging is new technology that utilizes and analyses high definition cross sections of your retina and optic nerve which can reveal signs of disease in exquisite detail that are invisible to traditional examination methods.
Color Vision. The Pseudo-isochromic Color Testing plates are used to determine the presence of red-green and blue-yellow color deficiencies.
Depth Perception. A test to determine the presence of three-dimensional vision or stereopsis (binocular vision). Determines the presence of conditions such as amblyopia (lazy eye) or strabismus (cross-eyes).
Auto Refraction. Computer controlled instrument used to provide an objective measurement of your refractive error or prescription for glasses or contact lenses. This quick, simple and painless test determines the depth and shape of the eyes by measuring how light is changed as it enters the eye.
Autokeratometry. A computerized diagnostic instrument for measuring the curvature of the anterior surface of the cornea, particularly for assessing the extent and axis of astigmatism.
Corneal Topography (Keratography) – (Contact Lens Exams). A non-invasive medical imaging technique used for mapping the surface curvature of the cornea. Provides a three-dimensional map of the cornea for fitting contact lenses and diagnosing and treating a number of medical conditions.
Lensometry. This computerized measurement of your current eyeglass prescription allows the doctor to determine if there is a change in your prescription.
Soft Touch Tonometry (iCare) Eye Pressure. The Glaucoma screener begins with the iCare test. This new device measures the internal pressure of your eyes. The small instrument uses a light probe to briefly contact the cornea. This barely noticed measurement replaces the “Puff of Air” device.
Visual Field Screening. This screener is to test your peripheral “side” vision. Glaucoma, stroke and retinitis pigmentosa are known to cause defects in your side vision.
