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 (P0. 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.
