Clonic orbscans and tropicamide.

摘要

To the Editor: We have previously shown that the Orbscan (Bausch & Lomb, Rochester, New York) was unable to map the corneal surfaces in eyes with shallow anterior chambers, displaying a clonic quad map, and that the clonic quad map disappeared after YAG iridotomy. We now report a case of clonic quad map with Orbscan in a patient with shallow anterior chambers that resolved after pupillary dilation.'
