Description

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.
