Iowa City, IA-The constricted pupil is both easy and hard to diagnose. As with the dilated pupil, there are easy-to-diagnose conditions in the patient with a small pupil-such as physiologic anisocoria, Horner's syndrome, and iris abnormalities-and these occur commonly. Pharmacologic miosis, Adie's pupil, and aberrant regeneration of the third nerve, however, are a bit harder to pinpoint, according to Andrew G. Lee, MD, who outlined his practical approach to diagnosing the constricted pupil.

New York-Structure does predict function, George A. (Jack) Cioffi, MD, told participants in the Glaucoma 2004 meeting here, and therefore measurement of the optic nerve head is important in assessing the presence and progression of the disease.
