ABSTRACT In the late nineteenth century authors established the concept of involvement of Automatic Nervous System (ANS), including both sympathetic and parasympathetic division in the various systemic disorders. ANS help to maintain the ocular blood flow at a suitable level during sudden increments in blood pressure and also influence the steady state level of Intraocular Pressure (IOP) by altering the rate of aqueous production in eye. Glaucoma is characterized by a progressive optic neuropathy resulting in irreversible damage to the optic nerve and visual field leading to blindness. Glaucoma has also been associated with ANS, which affects aqueous dynamics and therefore IOP. The diagnosis of autonomic neuropathy may be based on clinical symptoms on nerve biopsies or on attenuation of reflexes. In India the most common form of glaucoma is the Primary Open-Angle Glaucoma (POAG). The present study is undertaken with similar objectives to provide a further insight to this common and preventable disorder. AIMS To compare the autonomic functions of POAG and normal subjects (Control). MATERIALS AND METHODS The various autonomic function tests including Resting Heart Rate, Postural Pressor Response, Valsalva Ratio, Cold Pressor Response, Corrected QT Interval, T-Wave Amplitude of EKG were performed in 30 normal healthy subjects (Control) and 30 Primary Open Angle Glaucoma (POAG) patients in Gold Field Hospital, Faridabad. STATISTICAL ANALYSIS Intergroup mean differences were tested for significance by Stusent standard ‘t’ tests by using SPSS software version- 17.0. RESULTS There is significant (p
