MUTUAL ROLE OF SYMPATHETIC AND PARASYMPATHETIC IN SHAPING OF THE PUPILLARY REFLEX TO LIGHT: Pupillographic Studies

MUTUAL ROLE OF SYMPATHETIC AND PARASYMPATHETIC IN SHAPING OF THE PUPILLARY REFLEX TO LIGHT:... Abstract IN NUMEROUS pupillographic experiments made for clinical purposes we found various shapes of the pupillary reflex to light in conditions which, from clinical evidence, were due to pathologic processes or lesions of different localizations. The shapes varied, whether the lesions were in the autonomous centers or the periphery, either sympathetic or parasympathetic. Therefore it is the purpose of these studies to determine, by means of experimental lesions at the various levels of the reflex arc in some mammals, the sympathetic and/or the parasympathetic factors which are furnished, at these levels, to the integration of the normal shape of the pupillary reflex to light, with the goal of providing a comparative localization basis for pupillography as a tool of differential diagnosis of clinical lesions of the autonomic nervous system.

Abstract

Abstract IN NUMEROUS pupillographic experiments made for clinical purposes we found various shapes of the pupillary reflex to light in conditions which, from clinical evidence, were due to pathologic processes or lesions of different localizations. The shapes varied, whether the lesions were in the autonomous centers or the periphery, either sympathetic or parasympathetic. Therefore it is the purpose of these studies to determine, by means of experimental lesions at the various levels of the reflex arc in some mammals, the sympathetic and/or the parasympathetic factors which are furnished, at these levels, to the integration of the normal shape of the pupillary reflex to light, with the goal of providing a comparative localization basis for pupillography as a tool of differential diagnosis of clinical lesions of the autonomic nervous system.
