Changes in Ocular Perfusion Pressure in Response to Short Term Isometric Exercise in Young Adults.

Ocular Perfusion Pressure (OPP) is the pressure difference between the Mean Arterial Pressure (MAP) and theIntra Ocular Pressure (IOP). Decreased OPP could be a major risk factor for glaucoma. The aim is to study the effect ofIsometric exercise on OPP in apparently healthy young adults. Forty apparently healthy young adult volunteers comprising20 males and 20 females in the age group of 18-21 years were selected among MBBS Phase I students of JSS Medicalcollege, JSSU, Mysore. IOP and BP were recorded. Mean arterial pressure (MAP) and OPP were calculated. There was astatistically significant difference (p<0.05) in the mean OPP before and after performing Isometric exercise and betweenmales (50.58±0.72 to 56.85±1.15 mm Hg) and females (49.35 ± 1.66 to 56.71 ± 1.61 mm Hg). Physical activity in the formof Isometric exercise improves ocular blood flow - OPP. Hence regular exercise of prescribed intensity may prove useful forglaucomatous patients which enhance their OPP.
