Abstract

Introduction

Early recognition of glaucomatous optic neuropathy in the setting of physiologic IOP was described by Von Graefe in the mid 19th century[1].

Given the unclear etiology of the condition, many clinical definitions have been put forth guided by proposed mechanisms and efforts to describe the disease[2]

There is considerable debate in the literature whether Normal Tension Glaucoma (NTG) represents a distinct entity or is simply POAG with IOP within the normal range.(1)

The definition of NTG thus should be based on clinical history, co-morbidities, characteristic optic disc cupping and specific visual field defects.

We studied the Clinical profile, visual field changes and progression in patients with NTG
