Abstract
PURPOSE: To examine whether the local availabilities of ophthalmologists and optometrists were associated with outcomes related to the prevention and timely treatment of vision conditions. METHODS: Data on adults from the 2008 National Health Interview Survey were linked to county-level information on the numbers of ophthalmologists and optometrists per capita from the Area Health Resources File. Multivariate logistic regression models were estimated for whether individuals likely to perceive themselves as being at lower risk of vision conditions had undergone a dilated eye exam in the previous 2 years, whether individuals with diabetes had a dilated eye exam in the previous year, and whether individuals with an age-related eye disease (ARED) had lost vision due to the condition. The models included measures of local eye care provider availability and additional explanatory variables. RESULTS: The county-level availabilities of ophthalmologists and optometrists were positively and significantly related to the likelihood that perceived lower-risk individuals had undergone a dilated eye exam in the previous 2 years. Local eye care provider availability was not significantly related to whether individuals with diabetes had a dilated eye exam in the previous year. Greater county-level availability of ophthalmologists, but not optometrists, was associated with a significantly lower likelihood that individuals with an ARED had lost vision due to the condition. CONCLUSION: Public health interventions may be needed in order to increase access to preventive eye care in areas with limited overall eye care provider availability and to improve the treatment of vision conditions in areas with limited ophthalmologist availability.
