Angle-closure glaucoma is the main type of glaucoma in China, which is divided into acute and chronic angle-closure glaucoma. Previous studies from our group have found that, in lens excision combined with glaucoma surgery, accounted for 46.2% of patients were ligament abnormalities, such as lens subluxation with suspensory ligament relaxation. And it was more common in acute angle-closure glaucoma (55.8%). In acute angle-closure glaucoma, approximately 55.2% of suspensory ligament abnormalities were not diagnosed preoperatively depend on UBM and slit lamp examinations. The purpose of this study was to find a better preoperative diagnosis method of the suspensory ligament abnormality, and to observe the influence of the suspensory ligament abnormality on the occurrence, development and treatment effect of acute angle-closure glaucoma. We plan to collect patients with acute angle-closure glaucoma with monocular onset and exclude traumatic, secondary glaucoma and a history of intraocular surgery. The onset eyes were treated with combined operation, and divided into two groups according to the presence or absence of suspensory ligament abnormalities. The fellow eyes were treated with laser peripheral iridectomy, and followed examination, including UBM, anterior-segment OCT, and IOL master 700, before and after bow excitation test. Then follow up patients every six months. Ultimately, the fellow eyes will be treated with combined surgery after 2.5 years or the fellow eyes occur acute angle-closure glaucoma. In the end, we evaluate the sensitivity and specificity of each index, and the influence of suspensory ligament abnormality on angle-closure glaucoma progression.

Mechanical debridement is the traditional method for the treatment of peri-implant mucositis and its success depends on the patient's correct oral hygiene. It is believed that probiotics may help by their ability to modulate the oral biofilm, resulting in anti-inflammatory and anti-bacterial plaque action. The aim of this study is to evaluate the adjuvant effect of the probiotic Limosilactobacillus reuteri in the mechanical treatment of peri-implant mucositis. This study aims to include 32 subjects with implant-supported total rehabilitation and peri-implant mucositis, divided into test and control groups, equally subjected to professional mechanical debridement, with the administration of a daily GUM® PerioBalance® lozenge for 30 days added to the test group. Plaque Index, Bleeding Index and probing pocket depth are evaluated before the intervention (baseline) and at 6 and 10 weeks later.
