Purpose. The present investigation aimed to identify factors that predict reduced visual acuity in keratoconus from a prospective, longitudinal study.Methods. This report from the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study used 7 years of follow-up data from 953 CLEK subjects who did not have penetrating keratoplasty in either eye at baseline and who provided enough data to compute the slope of the change over time in high- or low-contrast best-corrected visual acuity (BCVA). Outcome measures included these slopes and whether the number of letters correctly read decreased by 10 letters or more in at least one eye in 7 …


Effects Of Retinal Image Degradation On Pre-Attentive Visual Search (Pavs) Efficiency For Flicker, Movement And Orientation Stimuli, Peter Davison, James Loughman Jan 2006

Effects Of Retinal Image Degradation On Pre-Attentive Visual Search (Pavs) Efficiency For Flicker, Movement And Orientation Stimuli, Peter Davison, James Loughman

Articles

Background: Previous research has shown that several clinical conditions cause increased preattentive visual search (PAVS) times, implying reduced parallel search capabilities in glaucoma and DLB dementia. The purpose of the research reported here was to examine for the first time the resistance of PAVS to dioptric blur using targets differing from the background in terms of flicker, vertical displacement, and orientation. Resistance would enhance the applicability of PAVS as a screening method for glaucoma and other clinical conditions affecting performance of a substantial area of the retina. Method: Computer generated flicker, orientation and vertical displacement targets were used to assess …
