Abstract

In order to study the ocular symptoms of lesions of the optic chiasm, the following classification, although somewhat artificial, naturally suggests itself:

1. The anatomic relations and structure of the optic chiasm.

2. Anomalies of the visual field.

3. Ophthalmoscopic changes.

4. Anomalies of the external ocular muscles.

5. Alterations in the pupil reflexes, with special reference to the hemiopic pupillary inaction.

6. The lesions which produce alteration in the structure and function of the optic chiasm and give rise to the ocular symptoms from which their position is inferred.

7. Diseases of the pituitary body, with special reference to the ocular symptoms of acromegaly.

8. Simulation of chiasm disease by other affections, for example, hysteria, locomotor ataxia, brain tumors.

9. The effect of certain toxic agents in causing lesions of the optic chiasm.

ANATOMIC RELATIONS.  Beneath the floor of the third ventricle the optic chiasm rests in the optic
