Analyzers, Physiologic, Visual Function, Eye Structure

Definition : Visual function physiologic analyzers that measure the interior structures of the eye (e.g., anterior segment biometrics, corneal shape and thickness, anterior chamber angle information, iris morphology) in a non-contact manner through a combination of optical coherence tomography and corneal topography. The analyzers consist of a patient interface with a chin rest on a corneal topographer into which the patient gazes with the dilated pupil. A Placido disk (series of concentric rings) is projected onto the eye. The rings are reflected back from the cornea and are captured by a camera and analyzed by a computer to create a topographic map of the cornea using special computer software. When combined with a corneal thickness map (pachymetry) from an anterior segment optical coherence tomographer, the analyzers provide information about the back surface of the cornea and therefore the entire cornea. Other features include automatic-alignment tracking software to compensate for eye movements while tracking the corneal vertex. Dedicated software allows the analyzers to produce visual images and reports of results that may be displayed on a screen and/or printed out. Visual function physiologic analyzers of eye structure are used by ophthalmologists to detect eye structure abnormalities and aid in patient selection for various ophthalmological procedures (e.g., refractive surgery, aspheric intraocular lens selection, contact lens fitting, pre- and post-excimer laser surgery, glaucoma surgery, corneal transplant, and phakic intraocular lens implantation).
