Your Opinions Count—
Take the 21st Annual Preferences and Trends (PAT) Survey

How do your practice patterns compare with those of your ASRS colleagues in the United States and around the world? It’s easy to find out—take the 2019 PAT Survey.

Each year since 1999, the ASRS PAT Survey has measured our members’ preferences on a wide range of medical, surgical, and socioeconomic topics. You can take the PAT Survey from your smartphone, tablet, or computer, whenever and wherever it’s most convenient for you.

Your ASRS member username and password will give you instant access to the PAT Survey. And if you don’t complete the whole survey in one session, you can come back to it as often as you’d like.

See how your answers compare
Want to see how your ASRS colleagues answered the PAT Survey questions? As soon as you complete the survey, you’ll get real-time results showing how your answer to each question compares with those of everyone who has taken the survey. Final results will compare US and international ASRS members’ responses to each question.

Tracking key trending data 

In addition to providing a yearly snapshot of retina specialists’ preferences, the PAT Survey collects longitudinal data allowing us to track significant trends in retina practice. The 2019 final survey results will include trending data on how ASRS members’ preferred treatment approaches have changed over the past several years.

Survey results will be released in July
PAT Survey Editor Thomas W. Stone, MD, will present the 2019 final survey results and multiyear trending data at the ASRS 37th Annual Meeting, July 26-30, in Chicago. A PAT Survey supplement—with complete 2019 survey results, trending data, and a roundtable discussion—will also be mailed as a supplement to Retina Times.

The greater the response, the more robust the data.

A Look at the Story Behind the PAT Survey 

Back in 1999, an ambitious Society initiative was launched—the brainchild of Kirk Packo, MD, then president of the Vitreous Society (as the ASRS then was known), and today’s ASRS President John Pollack, MD, who had completed his fellowship just 2 years earlier.  The new initiative was dubbed the Preferences and Trends (PAT) Survey. 

As John Pollack recalls in The History of the American Society of Retina Specialists: 25 Years,[1] “We decided the ASRS survey would be designed to identify new and evolving therapies and surgical techniques, controversies, preferences, and trends. It would help relatively isolated retina specialists know if they were practicing along the lines of other specialists … [and] would lead retina specialists to ponder, ‘Am I ahead of my time, on time, or behind the times?’ The PAT Survey would allow us to ‘take the pulse’ of retina specialists around the world—something that had never been done before.”

There was no shortage of ideas—from a first draft of about 250 questions, the original PAT Survey was honed down to 126 questions in 17 categories. (The survey has been trimmed over the years to an average of 75 questions.) Members took the original survey on paper or online, and the results were presented on individual hand-produced posters at the 1999 Annual Meeting of The Vitreous Society in Rome, Italy.

The PAT Survey results have been displayed at each ASRS Annual Meeting since then. As an ASRS member, you can access the complete PAT Survey archive

Kirk Packo and John Pollack served as the PAT Survey editors until 2005, when Robert Mittra, MD, became the editor and John Pollack stayed on board as co-editor. In 2011, J. Michael Jumper, MD, became the PAT Survey editor with Robert Mittra as his co-editor. Then, in 2013, Thomas Stone, MD, took over the reins as editor with Robert Mittra continuing to serve as co-editor until 2014.
