To define the prevalence and time course of significant changes in angle of deviation during the first months after the diagnosis of i nfantile esotropia and to determine whether long-term alignment and sensory out comes differ when surgical alignment is performed on infants with stable vs unst able angles of deviation. Prospective cohort study. setting: Institutional and c linical practice. patient population: Newly diagnosed patients with infantile es otropia (N=208). observation procedure: Preoperative measurements of the angle o f deviation on the initial visit and at approximate six-week intervals until su rgery was performed. main outcome measures: Ocular alignment at six weeks, one y ear, and four years postoperative and stereoacuity at age five to nine years. Ov erall, 57%of infants had an esodeviation on the second visit that was within 10 prism diopters (p.d.) of the deviation measured on the initial visit (stable gr oup), 33%had an increase of 10 p.d. or more (unstable group), and 11%had a dec rease of 10 p.d. or more. Among the 127 patients with additional preoperative vi sits, many switched between the stable and unstable categories during follow-up . Long-term, stable and unstable preoperative alignment groups had similar post operative motor alignment, re-operation rates, rates of prescription of hyperop ic, or bifocal spectacle correction and stereoacuity. It may not be necessary to wait for a “stable”angle of esodeviation before surgery since both alignment and sensory outcomes were similar for stable and unstable groups.

Functional improvements of binocular vision after strabismus surgery in adults are common but not well understood. In a prospective study, factors associated with stereoacuity outcome in patients with strabismus acquired following binocul ar vision maturation were investigated. Prospective data collection. Twenty-thr ee patients aged 14 to 85 years with acquired strabismus were enrolled. Random d ot stereoacuity was quantified using a battery of tests including the Randot Pre school Stereoacuity test, the Randot (version 2) shapes test, and the Randot But terfly test. Ninety-six percent of patients achieved measurable stereoacuity fo llowing successful eye realignment. Better median stereoacuity is achieved in pa tients with the following characteristics: ≤12 months of constant strabismus (6 0 vs 400 seconds of arc with > 12 months’strabismus, P < 0.001); a presurgical capacity for fine to moderate stereopsis (60 vs 400 seconds of arc with coarse o r no measurable stereopsis, P < 0.005); a presurgical capacity for macular fusio n (60 vs 400 seconds of arc with no measurable macular fusion capacity, P < 0.00 1); and postsurgical orthotropia (100 seconds of arc) or intermittent orthotropi a (100 seconds of arc vs 2000 seconds of arc with 5 to 8 prism diopters (PD) of postsurgical residual strabismus, P < 0.05). Surgical correction of acquired str abismus is associated with recovery of stereopsis. Factors associated with stere oacuity outcomes include duration of strabismus and presurgical binocular vision capacity. A postsurgical correction of orthotropia or intermittent orthotropia supports better stereoacuity than a larger residual angle of strabismus subtendi ng up to 8 PD of deviation.
