MedicalResearch.com: What is the background for this study?
Response: Dry eye disease is a complex multi-factorial condition, which affects between 5% to 50% of the adult population in different parts of the world. The condition can have profound effects on the ocular comfort, visual function, and quality of life of sufferers. In both clinical practice and academic research settings, validated questionnaires are frequently used to screen for dry eye symptomology, before clinical assessment of tear film homeostatic markers is conducted to make an overall diagnosis of dry eye disease.
Although a large number of validated symptomology questionnaires has previously been developed, the recently convened Tear Film and Ocular Surface Dry Eye Workshop II (TFOS DEWS II) identified that the considerable heterogeneities in the study populations, methodologies, and reference standards used in earlier diagnostic accuracy studies introduced significant challenges when trying to compare the diagnostic performance of these screening instruments.
The current study is the first to offer a direct comparison of five commonly used validated questionnaires within the same study population, and uses the global consensus criteria for tear film homeostatic disturbance developed by the TFOS DEWS II as the reference standard.
MedicalResearch.com Interview with:
Senior Director, Consumer Marketing Lead Shire
MedicalResearch.com: What is the background for this initiative? How does screen time affect eye health?
Response: Screen responsibly is an educational initiative about the intersection between our screen use and eye health. This initiative is underscored by new national survey data and aimed at increasing our dialogue about how to love both our screens and our eyes. Screen responsibly is an extension of the eyelove campaign, which Shire launched in 2016 to elevate the importance of eye health and raise awareness of the signs and symptoms of Chronic Dry Eye, commonly referred to as Dry Eye. Since being glued to your screen can trigger Dry Eye symptoms, it is important that people are aware of ways to screen responsibly.
MedicalResearch.com: How common is the problem of Dry Eye? How is it related to excessive screen time?
Response: In the United States, nearly 30 million adults report symptoms consistent with Dry Eye. Dry Eye symptoms include a burning, itchy, stinging or gritty feeling in the eyes, episodes of blurred vision, eye redness and watery eyes. Shire is committed to addressing unmet needs within the Dry Eye patient community, and to do so, we sought to better understand their current behaviors, perceptions and knowledge around a common trigger of Dry Eye symptoms – intense screen usage.

MedicalResearch.com: What are the main findings of the study?
Dr. Vehof: The current study provides the first empirical evidence that individuals with dry eye disease show altered pain sensitivity. Specifically, this study demonstrates that subjects with DED pain and discomfort complaints have lower pain threshold and pain tolerance of heat-based stimulus compared to those without.
These findings support the hypothesis that a subset of persons with DED is more sensitive to pain.
