The Impact of Social Determinants of Health on Vision Loss From Cataracts and Cataract Surgery Utilization in the United States-A National Health Interview Survey Analysis.

PURPOSE: To investigate the association of social determinants of health (SDOH) factors and cataract-related outcomes disparities. DESIGN: Cross-sectional, with a nationally representative sample. METHODS: We used publicly available data from the 2008, 2016, and 2017 National Health Interview Survey data sets. Outcome measures included self-reported prevalence for ever been diagnosed with cataract, vision loss secondary to cataracts, and the likelihood of undergoing cataract surgery. Survey-weighted, multivariable logistic regression models, adjusted for age, race and ethnicity, and other relevant covariates, were used to examine the association between SDOH factors and cataract-related outcomes. RESULTS: A total of 81,551 participants were included, who were predominantly between 18 and 44 years of age (49.6%), female (51.7%), and White (74.8%). Multivariable regression models with age as a covariate showed that individuals who were not working were more likely to report having cataracts than those who were working (P < .001). Those who needed but could not afford medical care in the past year were more likely to report vision loss secondary to cataracts than their counterparts (P < .001). Uninsured participants were less likely to report undergoing cataract surgery than those with private insurance (P = .03). Individuals with higher income (poverty-income ratio: 1.00-2.99 vs <1.00) were more likely to report undergoing cataract surgery (P = .04). CONCLUSIONS: Several SDOH factors were associated with disparities in rates of cataract-related outcomes. These findings highlight the importance of ophthalmologists screening for social risks in patients with cataract, as these social factors are important barriers for access to care.

An Accidental Nutritionist.

My career as an accidental nutritionist began with my immersion in cholera control, a cyclone disaster, a smallpox epidemic, and formal training in ophthalmology and epidemiology. Interest in blindness prevention inexplicably led me to (re)pioneer the effects, treatment, and prevention of vitamin A deficiency, while faced with intense criticism by many leading scientists in the nutrition community. The resulting efforts by the World Health Organization and UNICEF in support of programs for the global control of vitamin A deficiency still face vocal opposition by some senior scientists, despite having been estimated to have saved tens of millions of children from unnecessary death and blindness. This entire journey was largely an accident!

Magrabi ICO Cameroon Eye Institute, Yaoundé, Cameroon: Ophthalmology Subspecialty Patient Care and Training Center in Central Africa.

PURPOSE: To report establishment of the Magrabi ICO Cameroon Eye Institute at Yaoundé, Cameroon, as an ophthalmology subspecialty patient care and training center in Central Africa. DESIGN: Perspective. METHODS: Assessment of unpublished and published material. RESULTS: To improve, preserve and restore eye health and vision in a region with world-high prevalence of functional vision impairment and blindness, the Africa Eye Foundation established the Magrabi ICO Cameroon Eye Institute as an ophthalmology subspecialty patient care center for all in need and a training center for ophthalmologists, ophthalmology subspecialists, and allied personnel. In 2017, the year of its inauguration and the first year of operation, the Magrabi ICO Cameroon Eye Institute provided ophthalmology subspecialty care to more than 25 000 patients and surgery for pediatric and adult cataract, glaucoma, retinal disease, oculoplastic disorders, and other vision-threatening conditions. Outreach programs extended care to an additional 2500 individuals in rural communities and 7 training courses were conducted for ophthalmologists and allied personnel. CONCLUSION: Through ophthalmology subspecialty patient care and the training of ophthalmologists and allied personnel, Magrabi ICO Cameroon Eye Institute is acting to enhance vision and the quality of life for individuals and families in all segments of society.

The 2016 American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) Database: Characteristics and Methods.

PURPOSE: To describe the characteristics of the patient population included in the 2016 IRIS® Registry (Intelligent Research in Sight) database for analytic aims. DESIGN: Description of a clinical data registry. PARTICIPANTS: The 2016 IRIS Registry database consists of 17 363 018 unique patients from 7200 United States-based ophthalmologists in the United States. METHODS: Electronic health record (EHR) data were extracted from the participating practices and placed into a clinical database. The approach can be used across dozens of EHR systems. MAIN OUTCOME MEASURES: Demographic characteristics. RESULTS: The 2016 IRIS Registry database includes data about patient demographics, top-coded disease conditions, and visit rates. CONCLUSIONS: The IRIS Registry is a unique, large, real-world data set that is available for analytics to provide perspectives and to learn about current ophthalmic care and treatment outcomes. The IRIS Registry can be used to answer questions about practice patterns, use, disease prevalence, clinical outcomes, and the comparative effectiveness of different treatments. Limitations of the data are the same limitations associated with EHR data in terms of documentation errors or missing data and the lack of images. Currently, open access to the database is not available, but there are opportunities for researchers to submit proposals for analyses, for example through a Research to Prevent Blindness and American Academy of Ophthalmology Award for IRIS Registry Research.

The Johns Hopkins Bloomberg School of Public Health: A Brief History of a Century of Epidemiologic Discovery.

During its first century, the Johns Hopkins University Bloomberg School of Public Health has been home to several faculty members who have played leading roles in defining and expanding the field and science of epidemiology. They have done so by training leaders in the field, creating new methods and applications, and making relevant discoveries in the worlds of infectious and chronic diseases. These methodologic innovations and discoveries underlie many of today's major health policies and practices.

Burning Fossil Fuels: Impact of Climate Change on Health.

A recent, sophisticated granular analysis of climate change in the United States related to burning fossil fuels indicates a high likelihood of dramatic increases in temperature, wet-bulb temperature, and precipitation, which will dramatically impact the health and well-being of many Americans, particularly the young, the elderly, and the poor and marginalized. Other areas of the world, where they lack the resources to remediate these weather impacts, will be even more greatly affected. Too little attention is being paid to the impending health impact of accumulating greenhouse gases.
