Changing how glaucoma is treated: The National Institute for Health and Care Excellence (NICE) recently issued new guidelines for the treatment of thousands of patients with glaucoma in England following a major study at Moorfields. It is now recommending the use of SLT (selective laser trabeculoplasty) as a first line treatment option to lower internal eye pressure (intraocular pressure), instead of eye drops. Previously, SLT was advised as a second choice, and was only considered if there was issue with taking eye drops.

The change was made in large part due to the findings of the Laser in Glacuoma and Ocular Hypertension (LiGHT) Study, led by Gus Gazzard, ophthalmology consultant at Moorfields and professor of Glaucoma Studies at the UCL Institute of Ophthalmology.

Glaucoma is usually caused by fluid building up in the eye that increases pressure. SLT is a quick procedure which uses lasers to make it easier for fluid to leave the eye, and has now been found to be safe and effective as a first line treatment. It provides superior eye pressure stability to using drops and allows 74% of patients to manage their condition without drops for at least three years after treatment.

Gus Gazzard said: “It’s unusual for a trial such as the LiGHT Study to have such a profound impact, and fantastic that NICE have considered our results to be so robust that they have relied on them for a major shift in guidelines. It’s an excellent example of how bench-to-bedside research can make a real difference to patients’ lives.”

The LiGHT study was funded by the NIHR Biomedical Research Centre at Moorfields Eye Hospital with help from Moorfields Eye Charity.
