Subjective symptoms and medical history of patients with intermittent exotropia were extracted by a comprehensive survey based on a self-administered questionnaire according to the study protocol of the KIEMS.Results: The mean age of symptom onset was 5.5 years. The most common symptom reported in patients with intermittent exotropia was photophobia (52.1%), followed by diplopia at near fixation (7.3%) and distance fixation (6.2%). Preterm birth was found in 8.8%, and 4.1% had perinatal complications. A family history of strabismus was present in 14.9%, and 5.5% of patients had a family member who underwent strabismus surgery.Conclusions: The KIEMS is one of the largest clinical studies on intermittent exotropia. Intermittent exotropia frequently caused photophobia and diplopia, and patients with a family history was not uncommon.<\/jats:p>","DOI":"10.3341\/kjo.2023.0129","type":"journal-article","created":{"date-parts":[[2024,4,8]],"date-time":"2024-04-08T06:30:07Z","timestamp":1712557807000},"page":"194-202","update-policy":"http:\/\/dx.doi.org\/10.3341\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Self-Reported
