De Moraes CG, et al. - Experts tested the presumption that 24-hour IOP-related patterns recorded with a contact lens sensor (CLS) correlated with prior rates of visual field progression. Findings demonstrated a probable association of 24-hour CLS recordings with prior rates of visual field progression of glaucoma. Compared to the Goldmann mean IOP measured multiple times during office hours, this relationship appeared to be better. Hence, even in situations when insufficient historical visual field information was available, CLS could be useful to evaluate the risk of future functional loss.
