Purpose: To evaluate the outcome of 360° micropulse diode laser trabeculoplasty (MDLT) in patients with primary open angle glaucoma (POAG).

Methods: Retrospective review of 14 eyes of 14 patients with POAG that underwent MDLT either to achieve a better control of intraocular pressure (IOP) or to reduce the number of eyedrops for IOP control. Each eye underwent 360° MDLT (532 nm wavelength, 1000 mW power, 300 msec duration, 15% duty cicle, 300 µm diameter per spot). Patients were followed for at least 3 months. The intraocular pressure (IOP) was measured at baseline and at 1 month and 3months post-treatment. After treatment, the patients were maintained on their pre-treatment drug regimen until the 1 month visit.

Results: Mean age of the patients was 53.28 ± 6.74 years (44 - 62 years). Mean baseline IOP was 16.6 ± 2 mmHg. IOP significantly decreased at 30 days post MDLT (14.5 ± 1.6 mmHg; p < 0.0004) and maintained similar values at 90 days after treatment (14.6 ± 1.8 mmHg; p < 0.0009). At baseline, the mean number of medication was 1.71 ± 0.72 and 90 days after MDLT it was 1.14 ± 0.53 (p=0.002). Seven patients had a reduction in the number of eyedrops to control IOP. Four patients did not respond to treatment. There were no intra- or post-operative complications caused by MDLT. No pain or side effect was reported.

Conclusions: Our results suggest that 360° MDLT can be a safe and effective treatment option in patients with POAG.
