Table 2 The vessel densities of the optic nerve head region at the baseline and one hour after the laser peripheral iridotomy (LPI) in the three patient groups (group A = IOP increase ≤10 mmHg, group B = 10 mmHg < IOP increase ≤20 mmHg, and group C = IOP increase > 20 mmHg)

From: Changes in vessel density of the patients with narrow antenior chamber after an acute intraocular pressure elevation observed by OCT angiography
