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.
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.
