Auto Refraction is a computer-controlled machine used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses.

Standard / Extended Color Tests
some people are born with color deficiency while others acquire due to some ocular conditions such as cataracts, glaucoma and diabetes. For persons that fail or have difficulty with the standard test, an extended test should be administered. An extended test provides both qualitative (type: Protan, Deutan, Tritan) and quantitative (severity: mild, moderate, severe) assessment.

The IOL Master us used to measure the power of the intraocular lens used during the cataract surgery.
A-scan Ultrasound biometry, also referred to as just A-scan, utilizes an ultrasound device for diagnostic testing in Opthalmology practices. This device can determine the length of the eye and can be useful in diagnosing common sight disorders.
Visual Evoked Potential (VEP) measures the electrical activity in the vision system. When light from an image enters your eye, it is converted into electrical energy at the retina and travels through the optic nerve to the visual cortex of the brain which processes vision. 
Electroretinography (ERG) measures the electrical responses of various cell types in the retina, including the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion cells.
ICG Angiography is a procedure which images a layer of the posterior part of the eye.

B-scan ultra sound is used to check if the retina is intact, presence of tumors or optic nerve head drusen.



Tonopen to measure intra-ocular pressures, especially important in treatment of glaucoma.



Stereopsis test checks to see if both eyes are working together. Can you see in 3D?.



Fundus photos to monitor retina abnormalities (the inner layer of the eye)



Pachymetry to measure the central cornea thickness



Visual field evaluates side vision. Glaucoma and stroke have a specific pattern of vision loss.



Fluorescein angiography for retina evaluation.  A dye in injected into a vein on your arm and it quickly goes to the blood vessels of the eye. This dye fluoresces and allows the doctors to evaluate leakage in the back of the eye.


Optical Coherence Tomography, or OCT, is a non-contact, noninvasive imaging technique used to obtain high resolution cross-sectional images of the retina.
