- Abstract: A Dilated pupil with a loss of reactions to light and accommodation convergence exhibit these defects in varying degree, and occur under a variety of circumstances. These conditions include unilateral dilatation and fixity of the pupil as a result of injury to the eye and as the result of ipsilateral cerebral compression and bilaterally dilated and fixed pupils seen commonly in juvenile paresis and tabo-paresis. There are another unknown circumstances as tonic pupil. The authors presented a case of 22 years old Korean female under the diagnosis of dilated and fixed pupil which possibly originated from syphilis in as much as she was strongly positive reaction in serum S.T.S. and her abnormal pupil was recovered after anti-syphilitic therapy. The authors reviewed the literatures concerning these conditions and discussed about the possibility of early involvement of syphilis in the nervous system and the possible site of lesion which interefere pupillary reflex to light and accommodation-convergence. Finally authors commented the possible site of lesion is efferent pupilloconstrictor fibers which pass through the tentorial gap. In this region para-sympathetic pupilloconstrictor fibers, concentrated over the superior are of the oculomotor nerve, may be compressed upon its superior surface by inflammatory swelling of syphilitic involvement of adjacent structures.
