Abstract

An 80-year-old woman with normal-tension glaucoma was transferred to our clinic 9 years ago. She exhibited progressive visual field defect despite intraocular pressure in both eyes remaining stable in the low teens after treatment with prostaglandin-derivative eye drops. Increased short-term fluctuation in optic nerve head (ONH) blood flow was detected using laser speckle flowgraphy. After the patient was administered kallidinogenase tablets, the fluctuation was reduced and her visual field defect was ameliorated. However, the fluctuation increased and the visual field defect deteriorated after the patient discontinued the medication. The increased short-term fluctuation in ONH blood flow seemed to be associated with the development of glaucomatous visual field defect in this case. View Full-Text
