Abstract
SummaryPrimary glaucoma surgeries, whether minimally invasive or trabeculectomy, are usually effective in lowering intra‐ocular pressure. However, in a proportion of cases the initial procedure is ineffective or the procedure fails; in this eventuality, comprehensive glaucoma specialists need to be skilled in a number or other surgical strategies.Glaucoma drainage devices (‘tubes’) have long been used in complex or advanced cases, and are increasingly being used earlier on in the glaucoma treatment paradigm. In this part of the symposium, consideration will be given to instances where drainage tubes inserted into the anterior chamber are unlikely to be effective or have a high risk of failure. In such situations, there may be advantages for the drainage tube to be implanted through the posterior limbus or the pars plana.Consideration will be given to the indications, techniques, advantages and complications of posterior tube implantation. Clinical case scenarios will be described using anterior segment photography and video presentations, so that skills and knowledge will be transferred effectively; this will allow assimilation of these techniques into the clinical practice of glaucoma specialist participants.
