Tear immunoglobulin concentrations have been measured in 100 healthy people and 62 patients in different stages of trachoma. In healthy people the average IgA level was 27-8 mg/100 ml. There was no significant difference in the IgA level in various age groups and between the sexes. IgG was detected in 92 samples, and it was less than 1 mg/100 ml. IgM in tears was detected in only one sample. IgD was not detected in any specimen. In tracoma cases, the mean IgA level was found to be significantly lower (22-0 mg/100 ml) than in healthy people. There was no significant difference in IgA level between different stages of trachoma, IgG, IgD, and IgM could not be detected in any sample from the trachoma cases.
已对100名健康人和62名处于不同沙眼阶段的患者的泪液免疫球蛋白浓度进行了测量。在健康人中，平均IgA水平为27 - 8毫克/100毫升。不同年龄组和不同性别之间的IgA水平无显著差异。在92份样本中检测到了IgG，其含量低于1毫克/100毫升。仅在一份样本中检测到泪液中的IgM。在任何标本中均未检测到IgD。在沙眼病例中，发现平均IgA水平（22 - 0毫克/100毫升）显著低于健康人。沙眼不同阶段之间的IgA水平无显著差异，在沙眼病例的任何样本中均未检测到IgG、IgD和IgM。
