With a need for relevant information to design plans for screening, early diagnosis and timely management, the aim of this study was to present a systematic review of the sources to provide an estimate of the global prevalence of strabismus in different age and sex groups and determine the factors affecting its variability. A total of 7980 articles were found with final inclusion of 56 articles – a sample size of 229,396 people. Pooled prevalence of total strabismus was 1.93% (1.64, 2.21 CI), of exotropia was 1.23 (1, 1.46 CI) and of esotropia was 0.77 (0.59, 0.95 CI). Higher prevalence was found in some countries and ethnicities (western and white). Impact on quality of life is important. There was no significant difference for age or sex.
