    1. Optical Coherence Tomography Assessment of the Cornea During Corneal Swelling Should the Term “Descemet Membrane Folds” Be Reconsidered?

      Optical Coherence Tomography Assessment of the Cornea During Corneal Swelling Should the Term “Descemet Membrane Folds” Be Reconsidered?

      Purpose: Previous work has suggested that Descemet membrane (DM) folds arise in response to corneal swelling . However, their origin has not been closely explored. In this study, we used optical coherence tomography to evaluate whether DM folds arise secondary to folds in the middle stroma. Methods: Serial optical coherence tomography images of donor cornea pairs in deionized water were taken for each of the following corneal manipulations: 1) untreated, 2) DM and the endothelium removed, 3) excised in the region of the deep middle/posterior stroma, and 4) excised in the middle stroma. Results: For intact corneas, increasing duration in ...

    2. Quantitative analysis of iris parameters in keratoconus patients using optical coherence tomography

      Quantitative analysis of iris parameters in keratoconus patients using optical coherence tomography

      Purpose: To investigate the relationship between quantitative iris parameters and the presence of keratoconus. Methods: Cross-sectional observational study that included 15 affected eyes of 15 patients with keratoconus and 26 eyes of 26 normal age- and sex-matched controls. Iris parameters (area, thickness, and pupil diameter) of affected and unaffected eyes were measured under standardized light and dark conditions using anterior segment optical coherence tomography (AS-OCT). To identify optimal iris thickness cutoff points to maximize the sensitivity and specificity when discriminating keratoconus eyes from normal eyes, the analysis included the use of receiver operating characteristic (ROC) curves. Results: Iris thickness and ...
