Dilated Pupil of Argyll-Robertson Type in a Young Girl Showing Well-Marked Contraction to Closure of the Lids

Abstract

A STUDENT, aged 16, a somewhat anaemic but otherwise healthy girl. In February, 1913, I tested her refraction, and the left pupil was then normal. It was noticed by her mother to be enlarged in the following July. In May, 1914, I saw her again, and the condition has remained unchanged since then. In moderate light the left pupil is dilated to between two and three times the diameter of the right. It does not react to light either directly or consensually. It does contract well to convergence, though somewhat slowly. It also shows a marked contraction immediately after a voluntary closure of the lids. Vision is not affected either for distance or near. Right eye normal.
