Objectives:
To assess urologists' awareness of intraoperative floppy iris syndrome.
Materials And Methods:
A questionnaire composed of 21 questions was emailed to all of the Urology residency programs in the U.S. and all members of the Western section of the American Urological Association. Responses were collected and analyzed using statistical software.
Results:
A total of 175 responses were collected from residents, fellows, and attending physicians from a wide range of geographic locations, subspecialties, and practice settings. Thirty percent of the urologists would routinely discuss intraoperative floppy iris syndrome with patients prior to start of benign prostate hyperplasia treatment. Twenty-one percent of the respondents never asked patients about ophthalmologic conditions prior to benign prostate hyperplasia treatment. If patients had concurrent visual complaints, only 37% of the respondents would routinely encourage patients to speak to an ophthalmologist and only 13% would routinely refer patients to an ophthalmologist. A comparison among the subgroups based on training status and practice settings further showed that a significantly higher percentage of residents would not ask about visual complaints or refer patients with visual complaints to an ophthalmologist compared with fellows and attending physicians (P <.01); however, there was no significant difference between urologists in academic and nonacademic settings (P >.05).
Conclusion:
Despite continuing effort to educate physicians about intraoperative floppy iris syndrome, there still exists a knowledge gap that may compromise patient care and further education is needed.
