Laser is better than drops for glaucoma - SLT (Selective Laser Trabeculoplasty) is first line treatment in Moorfields study
A major new study has shown that SLT, a non invasive, pain-free laser that has been in use for many years, is better at controlling pressure in patients with open angle glaucoma than conventional eye drops.
Dr Gus Gazzard and colleagues at the world famous Moorfields Eye Hospital in London, UK reported the results of the LiGHT Study, which compared SLT to glaucoma eye drops as first-line therapy in a multi centre randomised controlled trial, in The Lancet journal.
Not only was the laser treatment better at reducing eye pressure and therefore controlling glaucoma than eye drops, it was also shown reduce the need for surgery and to be more cost-effective in the long term than eye drops. Patients tolerated the SLT laser treatment well and the decreased and more stable eye pressure that resulted from the treatment freed them from the burden of daily eye drops and their side effects.

Dr Vincent Lee has performed SLT laser treatment for glaucoma at South West Eye Surgery in Warrnambool for nearly 2 decades now with excellent results. A full eye check is necessary to determine suitability for SLT laser treatment.

While simple to perform and generally fairly accurate, a recent study has shown that the Van Herick technique for estimating anterior chamber angle depth can be unreliable in some circumstances.
This applies to males and myopes (people with short sight). The other risk factors are when this technique is performed on individuals of Asian and black race.

As such, it is recommended that when examining people in this demographic, a more reliable test is gonioscopy, especially when performed in a dark room.
One system of grading the anterior chamber angle depth is the Shaffer grading system, as depicted below:
