Visual Field
A visual field test measures the effectiveness of a patient’s peripheral vision. This test is used primarily for glaucoma suspects or for patients that have been diagnosed with glaucoma.
HRT
The HRT is a system that combines a laser-scanning camera and specialized software that evaluates the optic nerve. The HRT may diagnose glaucoma years before symptoms become apparent to the patient and is particularly useful at detecting small changes over time.
Specialized Medical Eye Testing Information
We recommend and perform various types of medical eye testing as necessary. The tests we perform include Automated Visual Field Testing, Heidelburg Retinal Tomography (HRT), Corneal Topography, Pachymetry, Schirmer’s test, and various methods of color testing. Read through the information on this page to learn more about these tests. Please direct any questions about these tests to one of our doctors during your exam. WE ARE NOW OFFERING HIGH DEFINITION OCULAR COHERENCE TOMOGRAPHY or HD-OCT! OCT allows our doctors to better monitor the subtle changes in your macula to allow for earlier detection and better management of macular degeneration and other retinal disorders.
OCT
Optical coherence tomography (OCT) is a relatively new diagnostic
modality that provides high-resolution, cross-sectional imaging of
ocular tissues. It is predominantly used for posterior segment
imaging to measure retinal and macula thickness and has been used to
study and monitor diseases such as vitreomacular traction, epiretinal
membranes, macular holes and macular edema in diabetes, vein occlusions
and uveitis.
Corneal Topography
Corneal topography provides the most detailed information about the curvature of the cornea. The computer generates a color map from the data. This information is useful to evaluate and correct astigmatism, monitor corneal disease, and detect irregularities in the corneal shape. Corneal topography is very useful for refractive surgery (LASIK) and CRT (Corneal Refractive Therapy).
Pachymetry
Pachymetry determines the thickness of the cornea. This is especially useful in LASIK evaluations, keratoconus patients and to evaluate corneal swelling.
Shirmer’s
Shirmer’s testing determines tear production to determine if the patient has dry eye syndrome.
Color testing
Color testing determines a patient’s level of color sensitivity and discernment
Visual Perceptual Evaluation
This includes assessment of left/right or directional skills, ability to
discriminate similarities and differences in shapes, visual memory skills, eye-hand
coordination skills and visual processing speed.
