Dacryology in China

Purpose: International Society of Dacryology held the IV International Congress in Stock -hohm on June 1996. I was warmly invited as a guest of honor beforehand to deliver a lecture on a special topic of 'Dacryology in China' there, so that the world might understand the dacryology in China, and thus the international growth of dacryology as a discipline would be promoted.Methods: In China tear lab research and clinical research of LG are nearly empty except a few papers published. We had studied 3 items on LS for 28 years before 1979, and put our attention mainly on dacryology since 1979 by 3 stages: (1) collecting literatures( 1979-81) ; (2) lab research(1981-84) and (3) clinical research, put DE as the key point by 4 steps: DE diagnosis(1984-86); DE treatment (1987-91); DE Condition Judgement(1989-92) & DE cause & mechanism( 1991-95).Results: In the past 44 years, esp. from 1979 on, in a planned way, we have systematically researched the dacryology with main results below; created new word 'Leiyexue'

Results: In the past 44 years, esp. from 1979 on, in a planned way, we have systematically researched the dacryology with main results below; created new word 'Leiyexue' in Chinese & its English words, dacryology & lacrimology by adding -ology to dacrya & lacrima; made LS consisted of reflex LG & LP, and basic LG besides; found out the normal & abnormal data of tear and serum LF & its iron bindingcapacity; MDH, LDH & isoenzymes; β2m; MDA & antioxidants; trace elements, prostaglandins, intramuscular gentamicin passing the blood-tear barrier; bacteria, fungi, anaerobe, virus & parasite; Ig, T cell & subsets, Langerhan cell, HLA antigen; in cidence(KCS,0.3-3% , trancomatous DE 0.003%); the parallel correlations between DE graded by rb, BUT & Sit; and in SS, lymphocytes infiltration in LG; Lab G & conjunctiva; LF ( < 100mg%) & β2m( > 1.7mg% ) ; and testosterone receptors in LG; negated presence of tear Beta-lysim; set up a series of models for researching & a complete set of measures to diagnose, grade, judge and treat DE, deviced new operations . AT & prescription for DE; proved SS being autoimmune & EB virus, its one cause. Conclusions: This relatively, overall & systematical research of dacryology already have been widely applied to practice with over 100 papers published. It indicates that LS & its disease as a scientific discipline under the term of dacryology to grow up is entirely possible and extremely needful. Eye Science 1998; 14 :1 - 8.
