Filter by:The primary study objective is to compare the effectiveness of the combination of phacoemulsification with intraocular lens implant with ELIOS or iStent inject W in reducing IOP at 12 months postoperatively.
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.
The investigators will test the hypothesis that images of the optic nerve head taken a 2 different eye pressures will yield strain estimates that are predictive of the course of glaucoma.
Prospective non-randomised cohort study enrolling patients with exfoliation glaucoma. All patients were ophthalmological examined at inclusion. Blood samples were taken for genetic analysis.
The goal of this randomised control trial is to learn about the effect of green tea consumption on patients with primary glaucoma. The main questions to answer are: 1. Is there any difference of intraocular pressure (IOP) in patient with primary glaucoma after 1 month, 3 months and 6 months who is consuming green tea compared to patient not consuming green tea? 2. Is there any difference of retina nerve fibre layer in patient with primary glaucoma after 1 month, 3months and 6 months who is consuming green tea compared to patient not consuming green tea? Researchers will compare patients with primary glaucoma who are consuming green tea and normal daily drinking to see if any affect to intraocular pressure and retina nerve fibre layer.
The purpose of this study is to evaluate long term safety and effectiveness of the STREAMLINE® SURGICAL SYSTEM
The researchers have used the ophthalmology textbook, clinical guideline consensus, the Internet conversation data and knowledge base of Zhongshan Ophthalmology Center in the early stage, combined with artificial feedback reinforcement learning and other techniques to fine-tune and train the LLM, and developed "Digital Twin Patient", a localized large language model that has the ability to answer ophthalmology-related medical questions, and also constructed a combination of automated model evaluation and manual evaluation by medical experts. The evaluation system combining automated model evaluation and manual evaluation by medical experts was constructed at the same time. This project intends to integrate "Digital Twin Patient" into undergraduate ophthalmology apprenticeship, simulate the consultation process of real patients through the online interaction between students and "Digital Twin Patient", explore the effect of "Digital Twin Patient" consultation teaching, provide emerging technology tools for guiding medical students to actively learn a variety of ophthalmology cases, cultivate clinical thinking, and provide the possibility of creating a new mode of intelligent teaching.
The aim of the study is to evaluate the agreement between three different grids in detecting central visual field defect in early glaucoma patients with reduced ganglion cell layer thickness.
The aim of this study is to create a large-scale register of all glaucoma patients diagnosed, followed and treated in a large tertiary centre specialising in glaucoma, in order to analyse whether specific factors influence the progression of the disease or guide our choice of treatment. This should lead to a better understanding of the disease and the factors to be taken into account when choosing the best treatment option for each patient, leading to safer, more effective and patient-centred care.
In conclusion, the study shows that the hospital-based group had a significantly higher screening uptake than the community-based group, reflecting that information from ophthalmologists and registered ophthalmic nurses is more effective and well-received than that from village health volunteers. The study suggests that increasing education and support for village health volunteers could enhance screening uptake. Factors influencing uptake include the age of FDRs, place of residence, education, presenting VA of probands, and treatment of probands. Utilizing this study's findings, spreading knowledge and training health officials at the district and sub-district levels could increase understanding of glaucoma and improve communication with the general public and at-risk groups, potentially increasing the response rate. Additionally, implementing a national free screening glaucoma program for at-risk populations, both in and outside hospitals, and organizing mobile screening units at the district level could be an effective prevention strategy against permanent vision loss from glaucoma.
