The Australian and New Zealand Glaucoma Society (ANZGS)
showcased a glimpse of the current practices in glaucoma intervention while reflecting on future challenges for managing the disease and patient care.
A session at the World Glaucoma e-Congress (WGC 2021) moderated by Professor Alex Hewitt from the Centre for Eye Research Australia
and the University of Tasmania, Professor Graham Lee, a professor of ophthalmology in Brisbane
and co-founder of the International Ophthalmology Portal, gave an update of trabeculectomy, ลาวสามัคคี
especially looking at “tips and tricks of ANZ (Australian and New Zealand) glaucoma surgeons.”
The evolution of trabeculectomy Trabeculectomy has evolved ever since its introduction in 1968.
The Moorfields Safer Surgery System for Trabeculectomy, developed by Sir Professor Peng Khaw (of Moorfields Eye Hospital,
London, United Kingdom) in the recent decades remains a major influence for this surgical technique.
In the study, 49 glaucoma specialists were surveyed via an ANZGS meeting using a 39-question online poll. T
he goal of the survey was to find out what glaucoma specialists would typically do for routine adult trabeculectomy for primary open-angle glaucoma (POAG).
The study showed that although a wide range of trabeculectomy techniques exist among ANZGS surgeons, there are some consistent practices currently in use.
Some of these are: creating a corneal traction suture (94%) using 7-0 vicryl or silk; a fornix-based conjunctival flap (92%); using anti-metabolites like mitomycin-C in 98% among the respondents.
They also looked at how these different techniques are applied: pledget (78%), injection (16%), and 80% administer a 0.02-0.03% solution.
Peripheral iridectomy was done 98% for phakic eyes and 72% for pseudophakic eyes.
Variations in techniques such as the use of the Ong Speculum and scleral flap formation were discussed (70% of surgeons use the rectangular flap).
Prof. Lee also discussed the pre-placed scleral flap suture technique (used by 63% of the surveyed specialists).
