斜视手术对眼血流动力学的影响

Impact of strabismus surgery on ocular hemodynamics

斜视手术可能引发眼前后节的血流动力学变化,进而影响术后眼健康和视功能。然而,不同的斜视手术所涉及肌肉类型、手术方式及手术切口不同对眼部血流动力学的影响及持续时间也不相同。斜视手术可能引起眼前节血流障碍,视网膜和脉络膜血流升高或降低。在斜视手术前借助虹膜血管造影技术、彩色多普勒超声检查及OCTA等方法评估眼前节缺血的危险因素,选择合适的手术方案,可降低斜视术后眼前节缺血的风险。同时,通过高精度的成像方法在术后监测和评估虹膜、视网膜和脉络膜血流变化,有助于缺血相关并发症早发现、早治疗。

Strabismus surgery may trigger hemodynamic changes in the anterior and posterior segments of the eye,further affecting postoperative ocular health and visual function.However,different strabismus surgeries involve different types of muscles,surgical methods,and surgical incisions that have different effects on ocular hemodynamics and duration.Strabismus surgery may cause impaired anterior segment blood flow and increased or decreased retinal and choroid blood flow.The risk of anterior segment ischemia can be reduced by using imaging methods such as iris angiography,color Doppler imaging,and optical coherence tomography angiography(OCTA)to assess the risk factors before strabismus surgery,and selecting an appropriate surgical plan.At the same time,high-precision imaging methods can be used to monitor and evaluate the changes of iris,retina and choroidal blood flow after surgery,which is helpful for the early detection and treatment of ischemia-related complications.
