Brief Summary:


The purpose of this study is to quantitatively assess the efficacy of monovision correction in the treatment of acquired small angle binocular diplopia in adult patients.


Twenty patients with symptomatic diplopia were enrolled in a prospective treatment trial. All had stable deviations of 10 prism diopters or less for over three months. Each received monovision spectacles and/ or contact lenses with distance correction in the dominant eye. Half received a +3.00 diopter (D) add and the others received +2.50 D. The validated and standardized Diplopia Questionnaire and Amblyopia and Strabismus Questionnaire (ASQE) were used to quantify the efficacy of monovision correction for diplopia by measuring the functional impact on vision-specific quality of life.

Primary Outcome Measures :
  1. Patients satisfaction with monovision was measured by standardized diplopia questionnaire and results reported in statistical terms on multiple measures tested on the questionnaire. [ Time Frame: 2 years ]
    To determine whether monovision correction was useful for the correction of small angle deviations in strabismic patients
