Delegates Discuss Dry Eye Measurements At 2017 Topcon National OCT Conference

Dry eye syndrome was a major topic of discussion at this year's Topcon National OCT Conference. One area of research delegates were particularly interested in concerned how dry eyes affect the accuracy of eye measurements.

Shehzad Naroo, a reader at Aston University's School of Life and Health Sciences, delivered one lecture devoted to the importance of considering dry eye when measuring a patient's eyes. Called "Not a Dry Eye in the Clinic? The Impact of Tear Film on Ocular Imaging," Naroo's presentation showed the extent to which dry eye syndrome affects standard eye measurement tests like the A-scan ultrasound biometry.

At the start of Naroo's lecture, he reminded his audience that tears form the outermost layer of the eye. Since dry eye patients don't have strong tear films, measuring their eyes without wetting drops could give inaccurate numbers. Naroo encouraged optometrists to use some kind of eye drops before measuring a dry eye patient's eyes.

In Naroo's opinion, the best eye drops to use are hyaluronic acid drops. Naroo prefers these drops over others because they last a long time and are extremely stable.

Naroo recommended using re-wetting drops before performing any eye measurement scans. In particular, Naroo highlighted the importance of wetting a dry eye patients eyes before an optical coherence tomography.

In closing, Naroo argued that the more these practices becomes standardized in the UK's eye health system, the more accurate their measurements will be. Naroo urged everyone at the conference to keep good records on patients with dry eye syndrome.

At least three million UK residents over the age of 45 complain of dry eyes. A few of the common symptoms of dry eye syndrome include eye itchiness, excessive tearing, red eye, eye discharge, and eye discomfort.

A few of the obvious reasons for the rise in the number of dry eye cases around the world include the prevalence of electronic screens, lack of sunlight, and nutrient deficient diets.

Although doctors officially distinguish between dry eye syndrome and digital vision strain, there's a great deal of crossover between the two disorders. Basically, people with only digital vision syndrome experience symptoms of dry eye after staring at an electronic screen for a long period of time.

There are many natural ways to combat dry eye and digital vision syndrome. A few easy things everyone can do include eating more foods with omega-3 fatty acids, walking outside in the sunlight, and drinking plenty of water. Dry eye sufferers can use over-the-counter re-wetting drops, but eye doctors caution patients not to become overly reliant on these products.

One effective tip for overcoming digital vision syndrome is to practice the 20-20-20 rule. This simple rule goes as follows: after staring at a computer screen for 20 minutes, look 20 feet away for at least 20 seconds. Eye doctors say this easy technique can help the eyes naturally re-lubricate.
