初期沙眼(特别是隐潜型)的及时诊断,对有效地防治该病来说,是具有重大意义的。在农村医务工作者的实际工作中,以及在本身不是眼科专家的一般医师的日常工作中,正确诊断沙眼,有着重要的作用。我们对很多居民进行了沙眼检查,并发现约有50%患者有典型的沙眼——有典型滤泡和浸润的“旺盛期”沙眼。另外一半患者则患有隐潜型和渐进型沙限,并不知不觉地成了本病散布的源泉。沙眼的这种临床上的变化,虽在多年前已为鲍克罗夫斯基教授所发现;然而,在广泛的实际工作中,这种隐潜型沙眼及其在流行病学上的意义,仍常被忽略。正如我们的检查资料所证明,隐潜型沙眼的经过,常不被患者所注意,患者 The early diagnosis of trachoma (especially latent type) timely diagnosis, for the effective prevention and treatment of the disease, is of great significance. Correct diagnosis of trachoma plays an important role in the practical work of rural medical workers and in the daily work of the general practitioner, who is not an eye specialist himself. We conducted trachoma examinations on many residents and found that about 50% of patients had typical trachoma - typical follicles and infiltrated “vigorous” trachoma. The other half of the patients had hidden latent and progressive sand limitation and unknowingly became the source of the disease. This clinical change in trachoma has been discovered by Professor Powkowski many years ago; however, in a wide range of practical work this latent trachoma and its epidemiological significance, Still often overlooked. As evidenced by our examination, the hidden latent trachoma is often not noticed by the patient. The patient
