Dr Willoughby discusses his experiences with the iStent
It has been shown in previous research that there is increased outflow resistance and as such reduced outflow facility in the trabecular meshwork in primary open-angle glaucoma patients.1 A potential treatment to increase the outflow facility is implantation of a trabecular microbypass stent. In his research, Dr Colin Willoughby (Belfast Health and Social Care Trust and Cathedral Eye Clinic, Belfast, Northern Ireland) looked at a treatment that would provide an effective solution for POAG patients with uncontrolled intraocular pressure (IOP) despite maximal medical treatment with evidence of progressive disease, particularly if combined with phacoemulisification.
