研究目的:

本临床研究旨在探讨孟加拉玫瑰红及532nm Nd:YAG激光介导的光化学胶原交联技术(Photochemical collagen crosslinking induced by rose Bengal and 532nm Nd:YAG laser, RB-PCL)应用于人体结膜组织移植的激光的功率及剂量,以及在剂量下的安全性和耐受性。次要目标是评估在最佳激光剂量下, RB‐PCL 技术在原发翼状胬肉自体结膜移植的初步临床疗效。以期开发一种不同于传统缝线技术的新的更为安全,有效的结膜组织粘合技术,为原发性翼状胬肉的治疗提供新的可能。  

Objectives of Study:

This clinical study aimed to investigate the dosage of Photochemical collagen crosslinking induced by rose Bengal and 532nm Nd:YAG laser (RB-PCL) laser for human conjunctival tissue transplantation, as well as the safety. The secondary objective is to evaluate the preliminary clinical efficacy of RB‐PCL technique in primary pterygium autoconjunctival transplantation at optimal laser doses. It will develop a new, safer and more effective conjunctival tissue bonding technology different from the traditional suture technique, and provide new treatment for primary pterygium.

药物成份或治疗方案详述:

通过采用激光激发光敏感物质的光化学反应、激活的光敏感剂的分子内部发生构像改变, 使该光敏感剂变化为激发态,激发态的分子变成呈不稳定状态,当这些激发态的分子与组织内胶原蛋白分子相遇后,可引起电子从激发态的光敏感剂转移至胶原分子,形成有极性的胶原分子,组织内有极性的胶原分子之间可形成共价键交联结合,从而引起组织和组织间快速有效的连接和粘合、并起到闭合伤口的作用.由于该过程为胶原分子间的连接、并且其紧密程度可达到水密闭的程度,因此也被称为纳米缝合技术(Nanosutures)。此外,该反应为光化学反应过程,因此为不产热过程,组织局部温度将不会升高,不会对局部组织造成热损伤。该技术所使用的光敏感剂孟加拉玫瑰红(Rose Bengal, RB)为 FDA 批准的眼科使用多年的角结膜染色剂,局部滴用对眼部无毒副作用;而激光设备则为眼科最常用的 532nmNd:YAG 激光,激光照射剂量(总剂量为 50-150J,其中能量密度为 0.25W/cm2 -0.5W/cm2,照射时间为100-600 秒)远低于临床眼科激光光凝使用的能量。 

Description for medicine or protocol of treatment in detail:

By using a laser to excite the photochemical reaction of a photosensitive substance, the molecule of the photosensitive agent changes its internal conformation to an excited state, and the excited molecule becomes unstable.When these excited molecules meet with collagen molecules in the tissue, electrons can be transferred from the excited photosensitiser to the collagen molecules, resulting in the formation of polar collagen molecules, which can form covalent bonds between the polar collagen molecules in the tissue. Covalent bonds are formed between the polar collagen molecules, resulting in rapid and effective tissue-to-tissue bonding and wound closure. The process is also known as Nanosutures because of the tightness of the collagen molecules to the extent that they are watertight. In addition, the reaction is photochemical and therefore non-thermal, so that the local temperature of the tissue does not increase and no thermal damage is caused to the local tissue. The laser device is a 532nm Nd:YAG laser, the most commonly used in ophthalmology, with a total dose of 50-150J, including an energy density of 0.25W/cm2 - 0.5W/cm2. The laser dose (total dose of 50-150 J, with an energy density of 0.25W/cm2 - 0.5W/cm2 and an exposure time of 100-600 seconds) is much lower than the energy used in clinical ophthalmic laser photocoagulation.
