PURPOSE: Videoreflective dacryomeniscometry (VRD) for evaluation of marginal t ear film has not been performed in patients with watery eye or in a controlled s tudy. We used VRD to evaluate the height of the central marginal lower lid tear film in normal adults and compared it with two watery-eye groups and a postoper ative dacryocystorhinostomy (DCR) group. DESIGN: Case-controlled interventional case series. METHODS: We evaluated with VRD 20 subjects with normal lacrimal dr ainage function, 21 patients with primary acquired nasolacrimal duct obstruction (PANDO), 28 patients with functional nasolacrimal duct obstruction (FNLDO), and a postoperative group of 14 patients derived from the previous two pathologic groups. Comparison between the four groups was performed to determine statisti cally significant differences between tear film height. RESULTS: PANDO and FNLDO groups were shown to have significantly greater median tear meniscus heights ([ TMH] PANDO: 620 μm, interquartile range [IQR] 453 μm; FNLDO: 731 μm, IQR 529 μm) than normal subjects (296 μm, IQR 214 μm; P< .001) and postoperative PAND O patients (265 μm, IQR 159 μm). There was no significant difference in TMH be tween PANDO and FNLDO groups preoperatively (P=.275). There was a reduction in m edian TMH postoperatively of 355 μm (P=.008) in PANDO and 360 μm (P=.068) in F NLDO. CONCLUSIONS: PANDO and FNLDO patients have similar preoperative TMH. In bo th these groups, TMH is significantly greater than in normal control subjects. L acrimal drainage surgery substantially reduces TMH as measured using VRD in PAND O.
