At the Eastern Section meeting of the Triological Society in New York, Robert J. Stanley and coworkers at the Mayo Clinic, Rochester, Minn, presented their experimental results on the relationship between intraorbital pressure and volume. They found that as intraorbital volume rises, pressure rises fairly slowly until a critical volume, when the pressure suddenly rises much more rapidly. It is at this point that vision may be compromised. They inserted a Foley balloon through the optic canal in 13 cadaver orbits and, using the retrodisplacement of the globe measured with an orbitonometer, plotted a standardized curve relating intraorbital pressures as a function of orbital retrodisplacement. They now intend to examine whether predictions from this curve will allow them to recognize which patterns are approaching critical intraorbital pressure levels and may benefit from orbital decompression surgery to preserve vision.— . . .
