A Comparison of the Intervisit Intraocular Pressure Fluctuation After 180 and 360 Degrees of Selective Laser Trabeculoplasty (SLT) as a Primary Therapy in Primary Open Angle Glaucoma and Ocular Hypertension

Abstract

This study suggests that 360-degree SLT is more efficacious in achieving smaller IOP fluctuations than treatment with 180-degree SLT.

Micropulse diode laser trabeculoplasty – 180‐degree treatment

“…According to this study, it seems that 180°treat-ment might be inadequate or that the treatment parameters that were used suboptimal. Prasad et al (2009) described increased efficacy with 360°c ompared with 180°procedure in patients treated with SLT.…”

Trabéculoplastie sélective au Laser Selecta (SLT) dans le traitement du glaucome chronique à angle ouvert : analyse rétrospective 12 ans après traitement d’une cohorte de 28 patients

“…Le traitement de 360 • de l'angle iridocornéen donne les meilleurs résultats [10,11]. Par ailleurs, le taux de succès dépend de la définition de « succès », plus ou moins sévère selon les études.…”

Surgical Management of Pseudoexfoliation Glaucoma

“…Other studies have suggested that 360-degree treatment is more effective than 180 degrees with IOP reductions reportedly as high as 9.08 mm Hg (35% reduction from baseline) 2 years after 360-degree SLT. 26 Baseline IOP also seems to affect the overall reduction in IOP and may serve as a predictor for response to 360-degree SLT. In a study by Shibata et al, 27 pretreatment IOPZ21 mm Hg resulted in a more dramatic decrease in IOP compared with a baseline IOP<21 mm Hg (33.5% ± 17.4% vs. 22.4% ± 17.9%; P<0.05, respectively) in Japanese patients treated with 360-degree SLT.…”
