INTRODUCTION

It is well known fact that an increased intraocular pressure (IOP) may cause a glaucomatous optic neuropathy. But the eye can tolerate a mild increase in IOP for a long time without any obvious defect in the optic nerve or visual field. Whereas many patients develop a glaucomatous optic nerve damage and a visual field defect. This evidence indicates that there are any other facters which cause similar optic nerve damage. The normal IOP can damage the optic nerve which is considerably vulnerable to the hydrostatic pressure. An acute ischemia in the optic nerve causes anterior ischemic optic neuropathy. It is often said that the chronic ischemia in the optic nerve may cause the normal-tension glaucoma. (NTG) It is very important to assess the difference of the ocular blood circulation between normal-tension glaucoma patients and normal subjects.
