Impact of the Reference Point for Epithelial Thickness Measurements [PDF]
Journal of Refractive Surgery, 2020 PURPOSE: To analyze the implications of different reference points on the read-out of epithelial thickness mapping. METHODS: A simulation for changing the reference point from normal-to-the-surface tangent to parallel vertical sections quantifying its effect on the read-out of ...

Corneal Epithelial Thickness Profile in the Diagnosis of Keratoconus
Journal of Refractive Surgery, 2009Purpose: To illustrate the hypothesis that epithelial thickness profile maps could be used as an adjunctive tool to improve the sensitivity and specificity of keratoconus screening by presenting a case series of examples. Methods: The Artemis very high-frequency digital ultrasound ...

On the methodology of the thyroid epithelial cell thickness determination
Journal of Microscopy, 1977SUMMARYThe average thickness of the thyroid epithelial cells may be determined either directly or indirectly. By the direct or caliper method, this thickness is overestimated as a result of which its empirical value must be divided by a correction factor Kd.

Utility of regional epithelial thickness measurements in corneal evaluations
Survey of Ophthalmology, 2020The measurement of regional corneal epithelial thickness and characterization of its behavior in response to changes in corneal architecture are increasingly drawing interest in clinical practice. The epithelium has tremendous capacity for remodeling and does so in response to underlying stromal pathology or changes in anterior corneal curvature ...
