Specialized Testing

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.


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 determines the thickness of the cornea. This is especially useful in LASIK evaluations, keratoconus patients and to evaluate corneal swelling.


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.

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
