Survey of glaucoma surgical preferences and post-operative care in the United Kingdom

BACKGROUND: To evaluate the spectrum of glaucoma surgery and the post-operative follow-up regimes undertaken among glaucoma specialists in the United Kingdom.

DESIGN: National survey.

PARTICIPANTS: Seventy-five glaucoma specialists (consultants and fellows).

METHODS: An eight-question survey was emailed to all glaucoma subspecialists members of the United Kingdom and Eire Glaucoma Society.

MAIN OUTCOME MEASURES: Surgery undertaken, post-operative management, awareness of intervention tariff and handling of the follow-up burden generated through surgery.

RESULTS: Almost all the participants (74/75: 99%) routinely performed trabeculectomy, 54 responders (72%) undertook tube surgery, and Minimally Invasive Glaucoma Surgery (MIGS) was more frequently undertaken (33.0%) than non-penetrating surgery (23%). In general, for patients with advanced glaucoma requiring a low target intraocular pressure, the most frequent primary intervention was trabeculectomy (99%), followed by tubes (64%). Similarly, in patients with less advanced glaucoma requiring moderate target intraocular pressure, participants preferred trabeculectomy (99%), followed by MIGS (60%). By the first 6 months after the procedure, trabeculectomy and Baerveldt tube implant required a larger number of postoperative visits (9 and 7, respectively), than iStent® and non-penetrating deep sclerectomy (3 and 5, respectively). The majority of participants were not aware of the costs of their interventions CONCLUSIONS: A wide variety of glaucoma surgery techniques are undertaken. Post-operative follow-up regimes are variable between techniques and for surgeons using the same technique. Trabeculectomy requires more follow-up than any other intervention. For patients requiring low IOP, trabeculectomy is the operation of choice for most surgeons.
