Figure. Scatterplot Representations for Linear Regression Models of Binocular Summation (BiS) Accounting for Age and Strabismic vs Control Status.

Figure

R values are depicted for each visual outcome. Strabismic vs control status was the only statistically significant variable for 2.5% Sloan low-contrast acuity (LCA) (P = .007), 1.25% Sloan LCA (P < .001), and Pelli-Robson contrast sensitivity (P = 0.02). Neither age nor strabismus vs control status were significantly associated with increased BiS for high-contrast Early Treatment Diabetic Retinopathy Study visual acuity chart (ETDRS VA) or sweep visual evoked potential (VEP) contrast sensitivity.
