Geographic disparities and surgical trends of strabismus surgery among Medicare beneficiaries (2016-2021).

This study highlights the disparity between the prevalence of adult strabismus in the United States and the limited number of surgeons performing adult strabismus surgery on Medicare beneficiaries. Only 12.2% of pediatric ophthalmologists billed Medicare for adult strabismus procedures during the study period. Additionally, geographic disparities of surgeons performing adult strabismus surgery were evident, with drastically different surgeon-to-patient ratios by state. Overall, the study raises concerns about the adequacy of the surgeon supply to meet the demand for adult strabismus cases.
