近二十年来冷凝疗法在眼科临床上的应用已日见广泛。先应用于摘除白内障,后发展至视网膜脱离代替电凝光凝和治疗眼睑结膜血管瘤乳头状瘤,以至恶性癌肿等。冷冻源有用半导体、高压氧、氟里昂,二氧化碳,氧化亚氮,液态空气和液氮等。其中以液氮温度较低,可达-196℃。但一般多用大小不同冷冻头进行冷凝。我们采用喷雾冷凝器,用液态空气或液氮直接向病变处喷射。温度低,不与组织接触,不会有冷凝器头粘着组织,引起部分组织脱落。因此方法简单,疗效好而经济,对眼睑良性
Condensation therapy in the past two decades in the clinical application of ophthalmology has become increasingly widespread. First applied to the removal of cataracts, after the development of retinal detachment instead of coagulation and treatment of conjunctival hemangioma papilloma, and even malignant cancer. Freeze source Useful semiconductors, hyperbaric oxygen, freon, carbon dioxide, nitrous oxide, liquid air and liquid nitrogen. Among them, the liquid nitrogen temperature is lower, up to -196 ℃. However, the general use of different sizes frozen head condensation. We use a spray condenser that injects directly into the lesion with liquid air or liquid nitrogen. Low temperature, not in contact with the tissue, there will be no condenser head adhesion, causing part of the tissue off. Therefore, the method is simple, effective and economical, eyelid benign
