Background: Pediatric strabismus is a common disorder that may lead to a severe decrease in visual quality. Updating the changes in disease characteristics through time is important for the diagnosis and prognostication of pediatric strabismus.

Methods: Retrospective cross-sectional study. Medical records of 1,101 patients with the diagnosis of pediatric strabismus from January 1st, 2020 to December 31st, 2020 were enrolled in this study. The medical records are included if suffcient information is available.

Results: We included 1,101 medical records in 2020. The prevalence of exotropia, esotropia and vertical strabismus were, in order, 68.4%, 29.3% and 2.3%. The prevalence of alternating strabismus and monocular strabismus were, in order, 74.8% and 25.2%. The prevalence of intermittent strabismus and manifest strabismus were, in order, 65.9% and 34.1%. Refractive errors exist in 87.3% of patients. Visual acuity could be recorded in 51.5% of patients, in which 31.8% of patients had a severe decrease of visual acuity (< 2/20). Amblyopia was recorded in 34% of patients, with 68.2% of whom from esotropia. Correcting refractive errors was the main treatment procedure (60.7%).

Conclusion: Pediatric strabismus may affect the children’s visual acuity deeply and therefore affect their quality of life. Early diagnosis of the disease takes the decisive role in preventing patients from amblyopia. As a large number of patients have refractive errors, early screening of the patient’s refraction is also mandatory.
