Ten patients with trichiasis were treated with cryosurgery by the standard retinal probe with nitrous oxide. A double freeze-thaw method was used. Nine of the patients had trachomatous trichiasis and one had conjunctival scarring. In only the latter case were the lashes destroyed, and these grew again after 2 months. Trachomatous trichiasis is frequently associated with entropion. The tarsal plate in such cases is often thickened and distorted, with extensive conjunctival scarring. The success of cryosurgical treatment of trichiasis depends not only on the type of probe used but perhaps also on the aetiology of the disease. To our knowledge no similar trial of this form of treatment of trichiasis has been carried out in eye centres in Africa south of the Sahara. Cryosurgery is simple to perform and of great potential use, particularly in areas where there is a shortage of skilled surgeons to perform the delicate eyelid operations often required in trichiasis.
10例睑内翻患者采用含一氧化二氮的标准视网膜探头进行冷冻手术治疗。采用双冻融法。9例患者为沙眼性睑内翻，1例为结膜瘢痕性睑内翻。仅在后一种情况下睫毛被破坏，2个月后睫毛再次生长。沙眼性睑内翻常伴有睑内翻。在这种情况下，睑板常增厚变形，伴有广泛的结膜瘢痕。冷冻手术治疗睑内翻的成功不仅取决于所使用探头的类型，还可能取决于疾病的病因。据我们所知，撒哈拉以南非洲的眼科中心尚未对这种形式的睑内翻治疗进行类似试验。冷冻手术操作简单，具有很大的潜在用途，特别是在缺乏熟练外科医生来进行睑内翻常需要的精细眼睑手术的地区。
