TESTING AT MERSI
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 that provide information about the visual system beyond the standard clinical examination of the eye. The main goal of the electrophysiological exam is to evaluate the function of the visual pathway from the retina’s photoreceptors to the brain’s visual cortex. Resultsnostic tests help establish the correct diagnosis or may rule out related ophthalmic diseases. from these diag
Visual Field testing
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 a computer, and a topographical map of the cornea is created.
Refraction
This test is only performed at MERSI for diagnostic purposes. We no longer provide refraction for eyeglass prescriptions.
A-Scan and B-scan
A high-frequency ultrasound used-dimensional, cross-sectional image of the eye and orbit. to create a two

A noninvasive photographic method that enables visualization and analysis of thelium. corneal endothe
Microperimetry
Assesses the visual function of a specific retina area and the fovea.
