The aim of this study was to demonstrate the effects of the influences of the technological world (optical, acoustical and stress) on intraocular pressure. The experiments were undertaken on rabbits for the following reasons: compliance with the laws governing experimentation, practicability, and the assumption that our premise was correct. Under normal living conditions we found that the rabbit's intraocular pressure followed a pattern of; mornings an average of 23.15 mm Hg, afternoons of 23.05 mm Hg, and evenings of 24.14 mm Hg. After subjection to intense optical and acoustical strain and after situations of stress the intraocular pressure rose on an average of 6 mm Hg (25%). It seems clear that we should make use of these results in our practice and give appropriate consultation and advice to our patients with raised intraocular pressure.
