Per capita expenditures of MEPS participants 18 years of age and older on ophthalmic medications from 2007–2016 by total and out-of-pocket expenditure. Total expenditures were the sum of payments from all payers (including the participant, insurance and other sources) for a given prescription. Out-of-pocket expenditures were a respondent’s self-paid amount for a given prescription after manufacturer discounts or rebates if applicable. P-values indicate the association between per capita expenditure and year by weighted linear regression.
