Efficacy of Selective Laser Trabeculoplasty Targeting Nasal Versus Inferior 180-degree

The Nasal 180° Selective Laser Trabeculoplasty (SLT) will be performed on the right eye. As per standard procedure, the laser will initially be set at 0.8 mJ (or 0.4 mJ for heavily pigmented TM). The energy level will then be adjusted in 0.1 mJ increments: increased until micro-bubble formation is observed or decreased if bubbles are noted. The desired endpoint is the production of a few fine 'champagne bubbles' every 2-3 laser spots. Larger gas bubbles and trabecular meshwork blanching will require the operator to titrate the power downwards in 0.1 mJ increments. Prophylactic IOP lowering and anti-inflammatory drops will be left to physician preference.
