Abstract:
AlM: To observe the early tear film changes after trabeculectomy using Keratograph 5M.METHODS:Fourty-one patients (46 eyes) of glaucoma who underwent trabeculectomy were involved. First tear break up time ( FTBUT ) , average tear break up time (ATBUT), non-invasive tear meniscus height (NlTMH), lipid layer thickness and meibomian gland scores were measured at 1d preoperatively and at 1d, 1wk, 1mo postoperatively.RESULTS:At 1d, 1wk and 1mo postoperatively, FTBUT and ATBUT decreased greatly (P<0. 05), as well as lipid layer thickness (P<0. 017). NlTMH at 1d postoperatively increased significantly, but at 1wk and 1mo postoperatively decreased greatly (P<0. 05). There was no significantly difference in meibomian gland scores between preoperation and postoperation (P>0. 05). CONCLUSlON: Keratograph 5M could be used to evaluate tear film function rapidly and accurately. Trabeculectomy significantly alters tear film stability and tear secretion in the short term after operation.
