The efficacy of low-energy selective laser trabeculoplasty.
OBJECTIVE
to analyze the efficacy of low-energy selective laser trabeculoplasty (SLT) in patients.


METHODS
in 74 patients (74 eyes) with ocular hypertension, suspected glaucoma, or primary open-angle glaucoma, SLT was the first-choice treatment. Thirty-nine patients in the low-energy group received treatment using half of conventional laser energy over 360° of the trabecular meshwork (at 100 points). Thirty-five patients in the control group received conventional laser energy. Patients were observed for 1 year. Complications and intraocular pressure (IOP) were observed.


RESULTS
postoperative transient IOP spike (≥ 3 mm Hg) occurred in three eyes on the day of treatment and partial peripheral anterior synechiae occurred in one eye 1 month after treatment only in the control group. Effective rates of treatment (≥ 20% IOP reduction) at week 2 and month 1, 3, 6, and 12 after treatment were 69.23%, 64.10%, 61.54%, 53.85%, and 48.72% in the low-energy group and 71.43%, 71.43%, 60%, 51.43%, and 48.57% in the control group, respectively. There was no statistically significant difference between the two groups at various time points (P = .836, .501, .892, .835, .990).


CONCLUSIONS
compared with SLT using conventional laser energy, low-energy SLT lowers IOP with fewer complications, making it a safe and effective option.
