Effectiveness of Selective Laser Trabeculoplasty Applied to 360° vs. 180° of the Angle

Figure 1

Kaplan–Meier curve comparing the cumulative probabilities survival following 180° and 360° of SLT (Lumenis, Coherent, Inc, Palo Alto, CA, USA). The shaded areas around each plot represent the 95% confidence bands. Success was defined as ≥20% IOP reduction from baseline with an IOP between 5–18 mmHg and ≤1 glaucoma medication added postoperatively. A failure was recorded if a patient either failed to meet success criteria at two consecutive follow-up visits or required an additional IOP-lowering procedure. The log-rank test was used to detect statistical differences between the curves. IOP = intraocular pressure; SLT = Selective Laser Trabeculoplasty; mmHg = millimeters of mercury.
