Serial Changes in Lamina Cribrosa Depth and Neuroretinal Parameters in Glaucoma: Impact of Choroidal Thickness.

Purpose: To determine whether: (1) change in lamina cribrosa depth occurs more frequently than change in neuroretinal parameters in glaucoma, and (2) Bruch's membrane or anterior sclera should be used as a reference plane when measuring laminar depth.

Design: Prospective observational study.

Participants: One hundred fifty-five glaucoma patients and 35 healthy controls.
