The CT scans of three patients whose eyes were lacerated by trauma failed t
o demonstrate the lens. A slit-lamp examination of those eyes clearly indic
ated that the lenses were present behind the iris but that they were swolle
n and opaque (intumescent cataract). Apparently, a shift of water into the
injured lens had reduced the expected hyperdense CT image of the lens to a
level that it was no longer discernible.
