Purpose: To investigate the distribution pattern of the strabismus surgery undertaken at an eye centre in Beijing, China. Methods: A retrospective analysis was conducted including the data of all strabismus surgeries performed in Beijing Tongren hospital for the 4 year period from 2003 to 2006. The proportions of different surgery types and their association with patients’ age and gender were analyzed. Result: During the study period, 8997 strabismus surgeries were performed. The number of the surgeries increased progressively each year from 1507 in 2003 to 2769 in 2006 ( p < 0.05). Intermittent exotropia was the most common of all strabismus surgeries (27.9%). Superior oblique palsy was the most common type among the paralytic strabismus surgeries. The proportions of different types of strabismus showed no significant change between successive years. Among the patients, the number of surgeries performed in the population aged 0–12 years was significantly higher than other age groups and increased from 35.37% in 2003 to 42.80% in 2006 ( p < 0.05). Conclusion: There has been a continuous increase in the number of strabismus operations in our eye centre in Beijing, and this pattern is especially obvious in children. The distribution of surgery type remained relatively constant each year. Surgery for intermittent exotropia is the most common type of procedure. [ABSTRACT FROM AUTHOR]
