Lamina Cribrosa Thickness in Patients With Keratoconus

Purpose: To evaluate the thickness and depth of lamina cribrosa (LC) in the optic nerve head region of the eyes in patients with nonglaucomatous keratoconus and to compare the thickness and depth with those of age-matched controls.
Methods: This was a cross-sectional, observational study comprising 45 patients with keratoconus and 56 healthy subjects. Analysis of LC imaging was performed using spectral domain optical coherence tomography. Data collected included spherical equivalent, central corneal thickness, axial length, intraocular pressure, and keratometry.
Results: Eyes with keratoconus had significantly thinner LC (174.9 ± 11.4 vs. 249.1 ± 4.9 μm, P
