Selective Laser Trabeculoplasty in Primary Angle-closure Glaucoma After Laser Peripheral Iridotomy

Abstract

The safety and efficacy of SLT was equivalent in PAC/PACG and POAG.

Feasibility of laser trabeculoplasty in angle closure glaucoma: a review of favourable histopathological findings in narrow angles

“…Studies involving the use of ALT and SLT in cases of angle closure have demonstrated efficacy when these methods are associated with previous procedures promoting a greater exposure of the TM such as peripheral iridotomy . Although a direct relationship can be established between the structural changes induced by ALT in the TM, involving enhanced aqueous humour outflow, and reduction of the IOP, similar correlations cannot be easily established with SLT although the effect is similar.…”

“…On the basis of the few studies available, both ALT and, more recently, SLT may be considered a new therapeutic option for the reduction of IOP in patients with different signs and symptoms of PACG showing more than 90° of visible pigmented TM before or after peripheral iridotomy . Within this context, SLT shows similar efficacy and a lower risk of complications because it tends to cause lower levels of secondary inflammation .…”

A Review of Selective Laser Trabeculoplasty: Recent Findings and Current Perspectives

“…In patients who had controlled IOP of PAC/PACG under medication but were intolerant of the medications, SLT achieved a reduction of 1.6 medications. The success rate of SLT in reducing IOP by at least 20% was 84.7% in the PAC/PACG group, and the clinical outcomes were comparable to those in the POAG group [15]. …”

“…In the majority of these, an increase in IOP was detected only on the day of the SLT procedure and was controlled by medications and not considered a long-term complication. Roughly 2–26.2% of glaucoma patients experienced a temporary postoperative IOP spike [15, 16, 22, 34]. In Ali Aljasim et al’s study, an IOP spike of 10 mmHg was detected in 10% of PAC/PACG patients and 5% of POAG patients 1 h after the procedure [15].…”

Narayaaswamy et al reported an increase in IOP greater than 5 mmHg in 2% of PAC/PACG patients 30–60 min following SLT [16].…”
