Filter by:Glaucoma is the leading cause of irreversible vision loss in people aged 50 years and older worldwide, second only to cataracts. Ultrasound Cyclo Plasty was first proposed as a new minimally invasive technique in the 1980 s. In recent years, many clinical studies at home and abroad have confirmed the effectiveness, safety and repeatability of UCP. The ciliary body is the target organ of UCP, and the range and accuracy of intraoperative destruction of the ciliary body are the key factors affecting the success or failure of the operation. The production of aqueous humor is closely related to the ciliary body. The dynamic balance of its production and discharge can affect IOP, and its content can directly reflect the intraocular environment. Besides,tears are easy to collect and can be used for follow-up. Previous studies have shown that various proteins in aqueous humor or tear can provide a basis for the pathophysiological changes of glaucoma, and can also be a potential biomarker for predicting the success of anti-glaucoma surgery. At present, UCP related research focuses on its effectiveness and safety, mainly reflected in three aspects : postoperative intraocular pressure, number of anti-glaucoma drugs and complications, and lack of relevant indicators that directly reflect postoperative intraocular environment changes. The purpose of this study was to reveal the changes of cytokines in aqueous humor after UCP in patients with primary glaucoma, to analyze the possible causes of these factors, and to speculate the effect of their interaction on the surgical effect, in order to increase the predictability of UCP procedure.
Importance: Lipid layer thickness (LLT) reflects the lipid components of tear film, but is affected by the mucocutaneous components. This study investigated the therapeutic effect of the treatments for aqueous-deficient dry eye (ADDE) on LLT. Objective: To investigate the effect of ADDE and its treatments on LLT measurements by tear interferometry. Design, Setting, and Participants: This prospective comparative interventional study included 152 eyes from 152 patients with ADDE. Interventions: Participants were classified into four groups: control group (Group 1), 3% diquafosol group (Group 2), punctal plug insertion group (Group 3), and combined treatment group (Group 4). Main Outcomes and Measures: Average LLT (LLTave) was measured using a LipiView® II tear interferometer at baseline and one month after treatments.
Pain neuroscience education (PNE) aims to explain to patients the biological and physiological processes involved in a pain experience and, more importantly, defocus the issues associated with the anatomical structures. It has been demonstrated for musculoskeletal pain, PNE provides compelling evidence in reducing pain, disability, pain catastrophization, and limited physical movement. Rotator cuff tears (RCT) often lead to pain aggrevation, deterioration of patients' functioning and considerable economic burden for health care resources requiring consultations, physiotherapy, radiological examinations and surgery. Despite costly arthroscopic surgeries and long-term physiotherapy treatments, satisfactory results are scarce. The lack of satisfactory results at the end of all this effort suggests that some practices should be revised. Although PNE is likely to have beneficial effects on shoulder pathomechanics, to our knowledge, there is no randomized controlled research in the relevant literature investigating the effects of PNE in patients with an RCT. The present study aims to examine the effectiveness of PNE on clinical outcomes in a sample of patients with RCT.
This study aims to collect tear samples from 50 women who have been recently diagnosed with breast cancer.
