Two Cases of Ocular Pain Successfully Treated with Orento

Abstract

There are cases of intractable eye pain, which can be difficult to treat. The late Shogo Yamamoto treated un­explained eye pain with various Chinese herbal prescriptions. Among them, there were clinical trials of heating agents including orengedokuto and hangeshashinto, but no trials of orento are mentioned. Further, no trials of cases of eye pain treated with orento were found in several other collections of clinical trials ;however, here we report on two cases of intractable eye pain of unknown origin that showed significant effects when admin­istered orento. In case 1, unexplained eye pain appeared after cataract surgery and after various treatments were found to be ineffective, acupuncture treatment in our hospital showed a positive effect. In case 2, unex­plained eye pain developed without any obvious cause, and the pain was increased by acupuncture treatment at our hospital. A common finding in both cases was objective cooling of the upper abdomen. The eye pain was considered to be upper heat and the abdominal pain to be middle cold, thus a diagnosis of upper heat and mid­dle cold was made and orento administration begun. We therefore consider that orento could be listed as a treatment for unexplained eye pain.
