Isometric Handgrip Exercise

Glaucoma is the main cause for irreversible blindness in India. The main determinant of glaucoma is raised intraocular pressure (IOP) which is influenced by many factors. One of the main factors is physical exercise. Objective of this study is to exhibit the effect of isometric handgrip exercise using Smedley’s handgrip dynamometer on IOP among young adult males in the south Indian population. In this quasi experimental study, 150 young healthy adult male subjects with ages between 15 to 40 years were selected on the basis of fulfilling our inclusion and exclusion criteria with the help of a questionnaire. Baseline IOP and maximum voluntary contraction (MVC) of the subjects were measured using non-contact tonometer and Smedley’s Handgrip Dynamometer, respectively. The subjects were instructed to hold the handgrip dynamometer with 20% of MVC in sustained manner for minimum 2 min or until fatigue sets in. IOP were measured on both eyes immediately and 15 min following exercise and IOP variation was analysed using paired t-test. A small but significant decrease in IOP was noted immediately as well as 15 min following exercise. Average fall in right eye was 1.75 mm Hg immediately and 2.14 mm Hg 15 min following exercise (P<0.01). The average fall in the left eye was 1.62 mm Hg immediately and 1.91 mm Hg after 15 min (P<0.01). Isometric handgrip exercise of the single upper limb showed significant reduction of IOP on both eyes following exercise and the decrease was much higher 15 min after exercise. This result can be extrapolated and clinically applied for glaucoma prevention and supplemented as lifestyle modification during glaucoma treatment.

Abstract OBJECTIVE To evaluate the effects of long-term (30-day) oral administration of melatonin on tear production, intraocular pressure (IOP), and concentration of melatonin in the tears and serum of healthy dogs. ANIMALS 20 healthy sexually intact adult male dogs. PROCEDURES 10 dogs were given melatonin (0.3 mg/kg, PO, q 24 h, administered in food at 9 am), and 10 dogs were given a placebo. Tear and serum melatonin concentrations, IOP, and tear production (determined with a Schirmer tear test) were recorded before (baseline) and 30 minutes, 3 hours, and 5 hours after administration of melatonin or the placebo on day 1 and 30 minutes after administration of melatonin or the placebo on days 8, 15, and 30. RESULTS Data collection time had significant effects on tear production, IOP, and tear melatonin concentration but not on serum melatonin concentration. Treatment (melatonin vs placebo) had a significant effect on tear melatonin concentration, but not on tear production, IOP, or serum melatonin concentration; however, tear melatonin concentration was significantly different between groups only 30 minutes after administration on day 1 and not at other times. CLINICAL RELEVANCE In healthy dogs, long-term administration of melatonin at a dosage of 0.3 mg/kg, PO, every 24 hours did not have any clinically important effects on tear production, IOP, or serum or tear melatonin concentrations.
