Effects of Atropine/2-PAM Chloride, Heat and Chemical Protective Clothing on Visual Performance

Abstract

Visual acuity, phoria, stereopsis and contrast sensitivity were assessed over six hours of continued exposure to combinations of atropine (2 mg) nad 2-PAM chloride (600 mg), severe heat/humidity (95 F/60 %RH), and wearing either the US Army battle dress uniform (BDU) or impermeable chemical protective clothing (MOPP-IV). Subjects were able to complete all six hours of testing under severe heat when wearing BDU's, but only lasted two hours under the same severe heat when wearing MOPP-IV. Acuity and phoria were significantly impaired by drug in the BDU conditions. Acuity, phoria and stereopsis were all significantly impaired by heat, drug and continued exposure under MOPP-IV. Acuity was significantly impaired by drug even during the first two hours of heat exposure in MOPP-IV. Keywords: Antidotes, Pralidoxime chloride; Heat stress physiology.
