Risk Factors of Strabismus Surgery among Pediatric Cerebral Palsy Population with Strabismus in Taiwan: A Population-Based Cohort Study.

BACKGROUND To identify the risk factors of strabismus surgery among Taiwanese children with severe cerebral palsy (CP) and strabismus. METHODS This retrospective nationwide population-based cohort study examined a cohort of newly diagnosed pediatric CP patients (age ≤ 10 years) between 1997 and 2013 with strabismus. The primary endpoint was strabismus surgery. A stepwise logistic regression was applied to determine the demographic factors, ophthalmic conditions, and comorbidities associated with strabismus surgery. RESULTS Out of 808 patients, 115 had received strabismus surgery. The significant factors correlated to strabismus surgeryin pediatric patients with severe CP and strabismus were CP diagnosis age < 4 years, residency in a suburban/rural area, low birth weight, and strabismic amblyopia. CONCLUSION In CP children with strabismus who have risk factors of younger CP diagnosis age (age < 4years), residency in a suburban/rural area, a low birthweight, and the presence of strabismic amblyopia, strabismus surgery should be considered.
