作者在沙特阿拉伯东部省对579名患者作了泪道并发症的研究,其中446人(77%)有沙眼,62人有严重的非活动性沙眼,并伴有下列泪道并发症:干眼症、泪点闭锁、泪点阻塞、泪道阻塞、鼻泪管阻塞、泪囊炎、泪囊扩张以及泪囊皮肤瘘管。以下列试验测定泪道机能:(1)Schirmer试验;(2)冲洗泪道:(3)泪囊炎患者之排出物做细菌培养;(4)结膜刮片姬氏染色。 7例鼻腔泪囊吻合术取泪囊组织、14例内翻矫正术取睑结膜组织活检。结果:62例124眼Schirmer试验中46眼(37%)低于10mm。此46眼中7眼(15%)无溶菌酶,22眼(48%)溶菌酶水平下降。在62例124眼中的47眼(38%)有泪小管阻
The authors studied lacrimal duct complications in 579 patients in eastern Saudi Arabia, of whom 446 (77%) had trachoma and 62 had severe inactive trachoma with the following lacrimal complications: dry eye Symptoms, tears atresia, punctate obstruction, lacrimal duct obstruction, nasolacrimal duct obstruction, dacryocystitis, dacryocystitis dilatation and lacrimal duct skin fistula. The lacrimal duct function was determined by the following tests: (1) Schirmer test; (2) irrigating the lacrimal duct; (3) bacterial culture of the effusion of dacryocystitis; (4) conjunctival smear Ji Ji staining. 7 cases of nasal dacryocystorhinostomy tear tissue taken, 14 cases of varus corrective surgery tarsal conjunctival tissue biopsy. RESULTS: Forty-six eyes (37%) in 62 eyes of 124 eyes with the Schirmer test were less than 10 mm. Seventeen eyes (15%) of these 46 eyes had no lysozyme and 22 eyes (48%) had decreased levels of lysozyme. Forty-seven eyes (38%) of 62 eyes (124 eyes) had tear ductal obstruction
