The Outcome of 270-Degree Selective Laser Trabeculoplasty

Table 3

IOP reduction from baseline at each time interval in primary open angle group (Group B).

Time interval	𝑛	Mean IOP reduction ± SD; (%) mmHg	𝑃 value
Pre-SLT to day 1	36	8.4 ± 4.9 (33.5)	<0.001
Pre-SLT to 1 week	36	5.2 ± 3.9 (20.7)	<0.001
Pre-SLT to 1 month	36	6.1 ± 3.6 (24.3)	<0.001
Pre-SLT to 3 months	36	6.5 ± 3.1 (25.9)	<0.001
Pre-SLT to 6 months	36	5.1 ± 3.0 (20.3)	<0.001

IOP: intraocular pressure; SD: standard deviation; SLT: selective laser trabeculoplasty.
