Eye bums are a process that develops during a chemical or thermal exposure that is of exceeding mass, contact time, chemical reactivity, and temperature until the exhaustion of the protective mechanisms of the eye. The most plastic description of this process can be given in images that are obtained by optical coherence tomography [5].

Acetylcholineesterase A 350 pM diameter coherent imaging fiber coated on the distal surface with a planar layer of analyte-sensitive polymer that was thin enough not to affect the fiber s imaging capabilities. It was applied to a pH sensor array and an ACh biosensor array (each contain 6000 optical sensor). Fibers were coated with an immobilized layer of poly (hydroxyethylmethacrylate)-N-flurosceinylacrylamide and AChE-fluorescein isothiocyanate isomer poly (acryloamide-co-N-acryl oxysuccinimide), respectively. The response time of the pH sensor was 2 s for a 0.5 unit increase in pH. The biosensor had a detection limit of 35 pM ACh and a linear response in the range 0.1 mM. [90]...

A pupillary diameter of 7 mm is usually adequate to permit most examination procedures to be performed, including peripheral retinal examination using the standard indirect biomicroscope or three-mirror fundus contact lens. However, the desired pupil size depends on what one wants to achieve. For example, the optical coherence tomographer, the Heidelberg retinal tomographer, and GDx instruments can all be used with an undilated pupil however, some dilation results in improved image quality and ease of use. 

Optical coherence tomography uses reflected light in a manner analogous to the use of sound waves in ultrasonography to create computerized cross-sectional images of the retina and optic disc, and also gives quantitative information about the peripapillary retinal nerve fiber layer thickness.
