Corneal stroma demarcation line after standard and high-intensity collagen crosslinking determined with anterior segment optical coherence tomography

PURPOSE: To use anterior segment optical coherence tomography (AS-OCT) to compare corneal stroma demarcation line depth after corneal collagen crosslinking (CXL) with 2 treatment protocols. SETTING

Central Corneal Thickness in Patients With Neovascular Age-Related Macular Degeneration

Purpose: To compare the central corneal thickness (CCT) measurements of patients with neovascular age-related macular degeneration (AMD) and control subjects. Methods: The CCT value (measured with ultrasound corneal pachymetry) of 130 eyes (130 patients, 1 eye from each patient) with neovascular AMD (AMD group) and 98 eyes (98 patients, 1 eye from each patient) of similar age, sex, and eye's axial length healthy control subjects (normal group) was compared. Results: The mean age (AMD group: 69.1 years vs. control group: 69.5 years, P = 0.81), sex (AMD group: 77 women, 59% vs. control group: 59 women, 60%, P = 0.77), and eye's axial length (AMD group: 25.05-mm vs. control group: 24.61-mm, P = 0.38) of patients with neovascular AMD and healthy control subjects were comparable. There were no statistically significant differences in the mean CCT measurements in the neovascular AMD group in comparison with the control group (549.44 vs. 544.35 mm, P = 0.11). Conclusions: CCT measurements do not differ in patients with neovascular AMD compared with healthy control subjects
