Fourier-Domain Optical Coherence Tomography for Monitoring the Lower Tear Meniscus in Dry Eye after Acupuncture Treatment

Figure 4

Mean change of tear meniscus depth (TMD) from baseline after 4 weeks of treatment for all subjects and each subgroup in acupuncture and artificial tear groups. ^†significant change from the baseline ( value < 0.05). significance compared to artificial tear group ( value < 0.05). significance between subtypes indicated ( value < 0.05). Significant comparisons include acupuncture group versus artificial tear group for all subjects (), LTD (), and Non-SSDE (); Non-SSDE versus SSDE () in acupuncture group.
