Web27 Jan 2024 · When analyzed by Scheimpflug tomography, our FECD patients showed no difference in the central corneal thickness and corneal volume when compared to the control group of cataract patients without any corneal pathologies.1 Recently, Sun et al. presented a new method to detect subclinical corneal edema in patients with FECD.2,3 … WebThe central corneal thickness pre-CXL and post-CXL was calculated from the OCT structural image after correcting for the cornea’s refractive index (assumed to be 1.38) (Fig. 3A, D). The OCT-measured local particle axial vibration velocity ( v z ( x , z , t ) ) was obtained from the optical phase difference Δ φ o p t ( x , z , t ) between 2 consecutive A-line scans at …
Assessment of corneal epithelial thickness in dry eye patients.
WebScleral thickness measurements of the posterior pole and of the peripapillary scleral flange were correlated with lamina cribrosa thickness measurements. Scleral thickness measurements at any location of examination were not significantly (all P>0.10) correlated with corneal thickness measurements. Web16 Mar 2024 · A pterygium is a raised, yellowish, wedge-shaped thickening on the white part of the eye, which can occasionally spread over the cornea, obstructing vision. It is painless (although it can cause irritation and dryness).
