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

Figure 6

FD-OCT representative images for the lower tear meniscus for each subgroup before and after 4 weeks of acupuncture or artificial tear treatment. (a) Significant improvements of tear meniscus parameters were observed after 4 weeks of acupuncture treatment compared with the control group for the LTD and Non-SSDE subgroups, but not for the SSDE. (b) There were no significant improvements of tear meniscus parameters compared with baseline in the control group for all three subtypes of dry eye.
