Fluorescein and ICG Angiography– Diagnostic tests used to more closely examine the retina and choroid. When dye is injected into a vein in the arm and travels throughout the blood vessels in the body, the dye passes through the blood vessels in the eye and a camera takes photographs of the retina or choroid blood vessels.
OCT (Optical coherence tomography) – A noninvasive imaging technology used to obtain high resolution cross-sectional images of the retina. OCT is similar to ultrasound testing, except that imaging is performed by measuring light rather than sound. OCT measures the retinal nerve fiber layer thickness in glaucoma and other diseases of the optic nerve.
IOL Master– Measures the axial length, corneal curvature and anterior depth of the eye and retina used to determine the power of lens implant used in cataract surgery.
Electrophysiological testing – A battery of tests which can be used to provide information about the visual system beyond the standard clinical examination of the eye. The primary objective of the electrophysiological examination is to assess the function of the visual pathway from the photoreceptors of the retina to the visual cortex of the brain. Information obtained from these diagnostic tests helps establish the correct diagnosis or may rule out related ophthalmic diseases.
Visual Field testing – A test used to measure the entire field of vision that helps diagnose and monitor glaucoma progression.
Corneal Topography – A test using an instrument that projects a series of illuminated rings onto the corneal surface, which are reflected back into the instrument. The reflected rings of light are analyzed by the computer and a topographical map of the cornea is generated.
Refraction – This test is only done at MERSI for diagnostic purposes. We no longer offer refraction for eye glass prescriptions.
A-Scan and B-scan – A high-frequency ultrasound used to produce a two-dimensional, cross-sectional view of the eye and the orbit.
Specular Microscopy – A noninvasive photographic technique that allows you to visualize and analyze the corneal endothelium.
Microperimetry – Assesses the visual function of a specific area of the retina and fovea.
