We evaluated recovery of binocularity in 15 chronically strabismic, non-fusing (with neutralizing prisms) adults following successful surgical alignment. We included > or =12-year-olds, with best corrected visual acuity (BCVA) > or =20/60, and excluded those with: anisoacuity> 2 lines-Snellen; failed realignment judged by> 10 prism diopters (PD) horizontal and> 4 PD vertical. Six-week outcomes were: fusion by Worth Four-Dots (WFDT) and Bagolini striated glasses (BSG) and stereopsis by Titmus test and the Netherlands organisation for applied scientific research (TNO) test. Baseline data in medians (range): age 18 (12-40) years, strabismus 45 (19-95) PD, duration 14 (0.5-24) years, 12 females; 12 exotropes, three esotropes; visual acuity was 20/20 in 10, while none had BCVA < 20/60. Postoperative strabismus measured 6 PD (range:0-10). By six weeks none suppressed: WFDT findings showed eight fused at distance and 13 at near; and on BSG figures were 10 and 13 respectively. Stereopsis was demonstrated by 13 on Titmus and by 10 on TNO tests. It is concluded that longstanding strabismic adults with good vision can recover fusion and stereopsis following successful squint surgery.
