q2 i? Near visual acuity with current eyeglasses improved significantly within the eccentric viewing training group, though the pre-post difference between groups was not significant. → Leat et al. 2017

Evidence¶

Leat et al. 2017¶

Susan J. Leat, Francis Fengqin Si, Deborah Gold, Dawn Pickering, Keith Gordon, and William Hodge. (2017).

q2 · i? · causal · r2

Near reading acuity measured with the Lighthouse chart at baseline and outcome in the randomized trial. The discussion reports acuity remained reduced (logMAR 1.28, close to 20/400), so "some improvement may be obtained for low-acuity tasks such as dressing, grooming, and mobility."

"There was a significant improvement in near visual acuity (with current eyeglasses) within the eccentric viewing training group"
