Normal Tension Glaucoma (NTG) is labelled when typical glaucomatous disc changes, visual field defects and open anterior chamber angles are associated with intraocular pressure (IOP) constantly below 21mm hg. Chronic low vascular perfusion and Raynaud's phenomenon are the main causes of normal tension glaucoma. Treatment is generally aimed at lowering IOP by 30% from pre-existing levels to 12-14 mm hg. Studies now show that the choice of medication may also be important in determining the outcome for the patients. The present review summarizes the treatment of NTG.Abstract
