| Outline of Final Research Achievements |
The aim of this study was to compare the eyelid pressure and dry eye severity before and 3 months after orbital decompression in patients with thyroid eye disease and between affected and unaffected sides in patients with unilateral facial nerve palsy. In patients with thyroid eye disease, eyelid pressure decreased and the morphology of the Meibomian gland and its orifices improved postoperatively. These results suggest that orbital decompression surgery reduced eyelid pressure, leading to improvement in Meibomian gland function. In patients with facial nerve palsy, eyelid pressure was lower and the tear meniscus height was higher on the affected side. These results indicate that low eyelid pressure decreased lacrimal pump function, leading to a high tear meniscus height. Although low eyelid pressure aggravates dry eye, a high tear meniscus height may offset it.
