Abstract

Transluminal Nd: YAG laser embolysis (TYE) is a method for the treatment of retinal artery occlusion (RAO). The objective of this study was to improve methods and reevaluate the efficacy and safety of modified TYE (MTYE) for the treatment of RAO with visible emboli in the fundus. We included non-arteritis RAO with fundus emboli visible in patients whose onset time was less than one month and who did not respond to conventional therapy. Seventeen patients (17 eyes) received MTYE treatment, and Fluorescence Fundus Angiography (FFA) was used to determine retinal artery flow recanalization changes before and after treatment. Compared with before MTYE, BCVA after treatment improved, and the results were statistically significant. BCVA (logMAR) was significantly improved at the last examination, changing from 1.23 ± 0.75 to 0.74 ± 0.7 (p < 0.001). Reperfusion was achieved in 15 eyes (88%), which was the initial surgery for treating RAO. During the follow-up period, vitreous hemorrhage occurred in two cases and two eyes, which were completely absorbed after one month of drug treatment, and no serious adverse reactions occurred in other patients. Therefore, MTYE can be used as an effective and safe treatment for RAO patients with visible emboli in the fundus. Data Access Statement: No.

改良YAG激光治疗视网膜动脉闭塞。

腔内Nd: YAG激光栓塞术（TYE）是治疗视网膜动脉闭塞（RAO）的一种方法。本研究的目的是改进方法并重新评估改良TYE （MTYE）治疗伴有眼底可见栓塞的RAO的有效性和安全性。我们纳入了发病时间少于一个月且对常规治疗无反应的伴有眼底栓塞的非动脉炎性RAO患者。17例患者（17只眼）接受MTYE治疗，采用荧光眼底血管造影（FFA）检测治疗前后视网膜动脉血流再通的变化。与MTYE前比较，治疗后BCVA改善，结果有统计学意义。BCVA （logMAR）在末次检查时有明显改善，由1.23±0.75降至0.74±0.7 （p < 0.05）

期刊介绍： Lasers in Medical Science (LIMS) has established itself as the leading international journal in the rapidly expanding field of medical and dental applications of lasers and light. It provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of medical lasers, including lasers in surgery, endoscopy, angioplasty, hyperthermia of tumors, and photodynamic therapy. In addition to medical laser applications, LIMS presents high-quality manuscripts on a wide range of dental topics, including aesthetic dentistry, endodontics, orthodontics, and prosthodontics. The journal publishes articles on the medical and dental applications of novel laser technologies, light delivery systems, sensors to monitor laser effects, basic laser-tissue interactions, and the modeling of laser-tissue interactions. Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
