A Survey of Glaucoma Surgery Practice Patterns in the Veterans Health Administration

Abstract

Abstract Introduction Glaucoma surgical practice patterns are not well described in the United States (US). This study aims to evaluate the indications for and potential barriers to glaucoma surgery in the Veterans Health Administration (VHA). Materials and Methods An anonymous 10-question survey using REDCap (Nashville, TN) software was sent by mail (with web link) and email to ophthalmology chiefs at the 86 academically affiliated Veterans Affairs Medical Centers (VAMCs). Academic-affiliated VAMCs were selected because of their patient range and role in ophthalmic education. Non-responders received two reminder e-mails and two phone calls; the survey was closed after 6 weeks. The data were analyzed using descriptive statistics. Results The response rate was 45% (39/86). Most respondents (92%) worked in an integrated eye clinic with both ophthalmology and optometry services. Almost half of the respondents (49%; 19/39) believed that laser trabeculoplasty (LTP) was an option for initial glaucoma therapy. Noncompliance was a commonly reported indication for LTP (95%), tube shunt procedures (65%), micro-invasive glaucoma surgery (59%), and trabeculectomy (48.7%). One third of the respondents believed that there were delays in glaucoma care. The respondents noted that significant barriers in access to surgery included lack of transportation (69%), scheduling challenges (62%), and delayed referral (62%). Conclusion This survey of glaucoma surgery practice patterns highlights the growing role of LTP and suggests that non-compliance and access remain significant barriers to glaucoma surgical care within the VHA.
