Table 1.
Observer visual and demographic characteristics. (1) Type; A, anisometropia; M, both strabismus and anisometropia; S, pure strabismus (2) NDE, non-dominant eye (R, right; L, left); (3) ocular alignment; ortho, orthophoria; XP, exophoria; XT, exotropia; ET, esotropia; AXT, alternating exotropia; HyperT, hypertropia; HypoT, hypotropia; (4) Stereoacuity; Randot stereoacuity. F, failed (>400 arcsec); note that treatment history includes any treatment beyond refractive correction with glasses or contact lenses. Age appropriate near correction was used for the various test distances. Units: visual acuity is given in logMAR units. Subjects A1, A2, M1, M4 and M5 were contact lens wearers. ETDRS VA (logMAR), early treatment diabetic retinopathy study visual acuity (logarithm of the minimum angle of resolution); plano, no refractive error.
