Clinical Observation of Laser Peripheral Iridoplasty with Number of Laser Shots in the Treatment of Acute Angle-Closure Glaucoma.

Objective: To quantitatively study the intraocular pressure (IOP) control and chamber angle opening degree of patients with acute angle-closure glaucoma (stage of attack) treated by laser peripheral iridoplasty (LPIP) with different numbers of laser shots, and to evaluate the efficacy and safety of different numbers of laser shots.

Methods: Fifty-five patients (60 eyes) with acute angle-closure glaucoma treated in our hospital from May 2019 to December 2020 were selected as the research subjects. All patients had poor intraocular pressure control (≥40 mmHg) after IOP-lowering drug therapy.

[Effect of bloodletting at tip of ear with different amounts on pain in patients with early-stage stye: a randomized controlled trial].

Objective: To compare the curative effect between bloodletting at tip of ear with different amounts combined with western medication and western medication alone for early-stage stye.

Methods: A total of 108 patients with early-stage stye were randomly divided into a 50 μL group (36 cases, 4 cases dropped off), a 100 μL group (36 cases, 2 cases dropped off) and a western medication group (36 cases, 5 cases dropped off). The patients in the western medication group were treated with levofloxacin eye drops and levofloxacin hydrochloride eye gel.
