Abstract

Purpose : It is challenging to obtain epidemiologic information on the incidence and prevalence of common eye conditions such as “stye” and “pink eye.” Patients are increasingly reliant on web-based searches to self assess eye-related symptoms. We hypothesize that search query analysis will provide insight into the seasonal and geographic patterns of common eye diseases.

Methods : We performed a retrospective search query analysis using the Google Trends database for ophthalmology-related symptoms and diagnoses. Queries were restricted to the USA within a 5-year interval (01/2012 - 01/2017). US climate data was gathered from the National Centers for Environmental Information. US population data was gathered from the US Census Bureau. Matlab Curve-Fitting Toolbox was used to perform linear and nonlinear regression analysis and goodness-of-fit was assessed by adjusted coefficients of determination (r2).

Results : Of search terms queried (N=115), periodic seasonal trends were observed for “stye” (r2=0.81), “eye drops” (r2=0.82), “pink eye” (r2=0.76), “itchy eye” (r2=0.67), “conjunctivitis” (r2=0.63), “floaters” (r2=0.61), “eye discharge” (r2=0.56),“chalazion (r2=0.46) and “corneal abrasion” (r2=0.30). Stye, floaters, itchy eye and abrasion queries peaked annually in June-August wheras pink eye, conjunctivitis and eye discharge queries peaked in Febuary-April. An increase in stye query frequency (16.4±0.2%) was appreciated during the summer compared to the winter. A linear relationship was observed between stye query frequency and increasing average annual temperature of a state (r2=0.59).

Conclusions : We demonstrate periodic seasonal trends in several ophthalmology-related search terms. We further illustrate an association between “stye” query frequency and increasing seasonal and geographic temperatures. We propose that search query analysis may serve as a powerful tool to guide future hypothesis-driven research and supplement current understanding of the epidemiology of common eye diseases.
