Using the IRIS Registry, investigators describe the rates of strabismus, strabismus surgery and strabismus reoperations among all age groups in the United States.
Investigators examined 1-year reoperation rate for strabismus surgery performed during 2013 and 2015.
Of 30,827,185 unique patients identified, 846,477 (2.75%) had a diagnosis of strabismus.
Approximately 1 in 20 patients with strabismus underwent surgery. Esotropia was the most common indication for surgery (30%), followed by exotropia (22%). Adjustable sutures were used in approximately 7% cases. The reoperation rate of was 6.7% over 1 year, and increased with age.
Similar to other EHR analyses, this IRIS Registry study was limited by possible miscoding. The rates of strabismus cannot be extrapolated to the population-based prevalence of strabismus.
This study describes practice patterns in the United States with respect to strabismus and strabismus surgery. The reoperation rate reported here could be used as a quality outcome benchmark for practitioners, although the percentage may not be a good representation of all ophthalmology practices.
