Keynote speaker Professor Tin Aung, Head of Glaucoma Services at the Singapore National Eye Centre, Singapore, will address symposium delegates regarding the efficacy of SLT in the treatment of Primary Angle Closure Glaucoma (PACG) - the leading cause of glaucoma-related blindness in Asia.(1)

An Ellex sponsored multi-country, randomized, controlled clinical trial comparing the pressure-lowering effect of SLT with that of (prostaglandin) conventional drug therapy for PACG, led by Professor Aung, has shown SLT to offer the same IOP-lowering effects as prostaglandins over six months. Professor Aung's group will present the preliminary six-month trial results at the upcoming Association for Research in Vision in Ophthalmology (ARVO), May 2012.
"SLT can be considered to be a viable, safe and effective alternative to medications for lowering the IOP in patients with PAC and PACG after iridotomy, provided there are areas of the angle that are open for SLT to be applied," said Professor Aung.
The results of Professor Aung and his team follow the 2009 trial by Ching-Lin Ho et al, which showed that SLT after iridotomy treatment, and with at least 90° of the trabeculum gonioscopically visible, is amenable to SLT with similar effectiveness to SLT in the treatment of POAG.
Beyond gonioscopy: Angle asessment - Ophthalmology Times Europe

Dynamic indentation gonioscopy remains the current reference standard for assessing the anterior chamber angle, but a variety of recently introduced objective imaging techniques may become useful adjuncts in clinical care, said Dr Tin Aung, PhD.
"The new technologies, which include methods of crosssection angle imaging using optical coherence tomography (OCT) and angle photography, are all easy to perform and each has unique advantages," said Dr Aung, consultant ophthalmologist, Singapore National Eye Centre, and associate professor of ophthalmology, National University of Singapore, Singapore. "While each of these modalities has disadvantages as well, [we hope] they will lead to exciting improvements in angle imaging.
"After all, we use a variety of imaging methods in [the care of patients with] glaucoma... for assessing the optic disc, retinal nerve fibre layer, and corneal thickness," he added. "Perhaps we should also include angle assessments among our imaging techniques in glaucoma."
A role for objective imaging techniques for angle assessment is underscored by consideration of the limitations of gonioscopy. Its performance requires training, interpretation is subjective and observerdependent, and the findings vary depending on room lighting conditions, lighting on the pupil, and the type of lens used. In addition, recording of the gonioscopy findings by some physicians is less than optimal, Dr Aung said.

"However, the problem with using ASOCT for diagnosing angle closure is that one has to identify contact between the iris and the trabecular meshwork, but the trabecular meshwork is not visible in most images," Dr Aung said. "Therefore, one must use the scleral spur, which lies behind the trabecular meshwork, as a landmark in both qualitative and quantitative assessments. Angle closure is determined by identifying contact between the iris and angle wall anterior to the sclera spur."
A study performed by Dr Aung and colleagues comparing ASOCT and gonioscopy for diagnosing angle closure demonstrated that the imaging technology had high sensitivity (98%) but lower specificity (54.4%) because its use resulted in diagnosis of angle closure in some patients who were considered to have an open angle on gonioscopy.
"Possible reasons accounting for the discrepancy between gonioscopic and ASOCT diagnosis include differences in the lighting conditions used for the two examinations, distortion of the angle configuration when performing gonioscopy, and use of different landmarks for the two methods," Dr Aung said.
In addition to its inability to visualize the trabecular meshwork in most cases, other disadvantages of ASOCT include the fact that scleral spur definition is difficult in up to 30% of images overall, and according to a study by Dr Aung and colleagues, at an even higher rate when assessing the inferior and superior quadrants.
