Background: Idiopathic intracranial hypertension (IIH) disproportionately affects women from socioeconomically disadvantaged communities, but specific social determinants of health have not been examined.

Methods: We used data from the National Institutes of Health's All of Us Research Program, an ongoing nationwide study of more than 300,000 diverse individuals in the United States. Height and weight were measured at baseline, and participants completed questionnaires about demographics, health care access, and quality of life. Women aged 18-50 years with IIH were identified through electronic health record data, excluding those with venous thrombosis, meningitis, hydrocephalus, or central nervous system neoplasms. We used logistic regression to compare questionnaire responses for IIH cases and controls, adjusting for age, race, ethnicity, annual income, and body mass index (BMI).

Results: We included 416 women with IIH and 107,111 women without IIH. The mean age was 38 years, and 49.3% identified as non-White. After adjusting for age, race/ethnicity, and BMI, women with IIH were more likely to be unemployed (odds ratio [OR] 1.40, 95% confidential interval [CI]: 1.14-1.71) and report delaying care because of difficulty affording copays (OR 1.47, 95% CI: 1.02-2.10) or specialist care (OR 1.52, 95% CI: 1.06-2.18). They also delayed care because of rural residence (OR 2.08, 95% CI: 1.25-3.47) and transportation limitations (OR 2.23, 95% CI: 1.55-3.20). Although women with IIH were more likely to be non-Hispanic Black (OR 1.66, 95% CI: 1.32-2.09), this association lost significance when controlling for BMI and income (OR 1.27, 95% CI: 0.96-1.68).

Conclusions: Women with IIH experience adverse social determinants of health beyond those associated with obesity alone.

Background: This study aims to determine the population-based incidence and characterize the features of nonarteritic anterior ischemic optic neuropathy (NAION) using the Rochester Epidemiology Project (REP).

Methods: All patients diagnosed with an optic neuropathy from January 1, 1990, to December 31, 2016, were retrospectively reviewed to identify incident cases of NAION using the REP database, which is a record-linkage system of medical records for all patient-physician encounters among Olmsted County, Minnesota residents. The overall incidence of NAION was estimated using the age-specific and sex-specific population figures for Olmsted County census data for 1990 through 2016. Visual outcomes and risk factors were evaluated. The systemic risk factors were compared with age-matched controls.

Results: One hundred four patients were diagnosed with NAION during the 26-year study period. The overall age and sex adjusted incidence was 3.89 per 100,000 individuals (95% confidence interval [CI]: 3.14-4.65). The incidence was 7.73 (CI: 6.24-9.22) in patients aged 40 years or older and 10.19 (CI: 8.15-12.23) in patients aged 50 years or older. Median age at diagnosis was 65 years (range, 40-90 years), and 59 (56.7%) were male. The median logMAR visual acuity at presentation was 0.35 (Snellen equivalent of 20/40) with 14 patients (13.5%) having vision of counting fingers or worse. Among the 91 patients with final visual acuity outcome data available, the median visual acuity was 0.40 (Snellen equivalent of 20/50) with 12 patients (13.2%) having vision of counting fingers or worse. Twenty-four patients (26.4%) were noted to have final acuity at least 3 Snellen lines worse than at presentation, whereas 17 patients (18.7%) were noted to improve by at least 3 lines. The median mean deviation on automated visual field testing was -10.2 dB at presentation and -11.1 dB at follow-up. Twenty-two patients (21.2%) suffered NAION in the fellow eye; the median interval between involvement of the first and second eyes was 1.39 years. Systemic diseases present in the NAION cohort included hypertension (79.8%), diabetes mellitus (39.4%), obstructive sleep apnea (23.1%), and hyperlipidemia (74.0%), which were all statistically higher than age-matched controls.

Conclusions: NAION is a relatively common optic neuropathy in elderly patients with vascular risk factors. Our data indicate that the incidence of NAION has remained relatively stable in the population of Olmsted County over the past 4 decades.
