“…In this study, the overall tear film LLT was not different between the control and incomplete NLDO patients and increased following silicone tube insertion. This finding is similar to the results of a previous study by Kubo et al [9], who reported that the lipid layer could not be extended to the corneal surface by decreased tear volume and leads to a thicker and irregular lipid layer. However, in our study, the LLT in the postoperative group was significantly higher than that of the control group, but there was no significant difference in TMH.…”

“…According to previous studies, tear protein components in patients are more alkaline, higher in calcium concentrations and inflammatory cytokines, and unstable compared with normal persons [78]. Kubo et al [9] reported that the tear lipid layer was thicker after dacryocystorhinostomy in four patients (five eyes). In their study, researchers determined the LLT by observing the specular reflected light from the tear's surface, a similar method to the ocular surface interferometer used in this study.…”

“…According to these previous studies, these tears were more alkaline, had a higher calcium concentration, contained inflammatory cytokines, and were unstable in the proportion of tear proteins compared with normal patients [78]. In 2001, there was a report that tear LLT after dacryocystorhinostomy [9]. Kubo et al [9] reported that the tear lipid layer was thicker after dacryocystorhinostomy in four patients (five eyes).…”

PurposeTo compare the tear film lipid layer thickness (LLT) between patients with incomplete nasolacrimal duct obstruction (NLDO) and normal controls and to analyze the changes in tear film LLT and blinking pattern after silicone tube intubation in NLDO patients.MethodsWe reviewed the medical records of 68 eyes in 52 incomplete NLDO patients who underwent silicone tube intubation from January 2017 to July 2017. The LLT, blinking pattern, and Meibomian gland image were measured with the LipiView II ocular surface interferometer. The Meibomian gland drop-out ratio was measured using the polygon selection tool in the Image J program. Tear meniscus height, which is the other lacrimal indicator, was assessed with spectral-domain optical coherence tomography.ResultsTear meniscus height was significantly decreased after silicone tube intubation (p < 0.01). Preoperative minimum, maximum, and average LLT values were 62.4 ± 24.0, 86.7 ± 17.9, and 71.7 ± 23.3 nm, respectively. Significant changes in the minimum, maximum, and average LLT (74.8 ± 23.6, 98.8 ± 11.0, and 91.6 ± 16.1 nm, respectively) were observed after silicone tube intubation (p < 0.001, p = 0.001, and p < 0.001). The partial blinking/total blinking ratio in 20 seconds and the Meibomian gland drop-out ratio showed no significant change after silicone tube intubation.ConclusionsOverall, the LLT was increased after silicone tube intubation. Silicone tube intubation may be helpful in maintaining LLT with a normalized of amount of tears.
