Shrapnel scratch of head: Hysterical amaurosis “?” On isolation in a dark room, the patient began to see light!

Case 461. (Briand and Kalt, February, 1917.)

A man may seek to exaggerate an anomaly of his eye which had existed before the war, in order to live comfortably far from the front.

A soldier sustained a slight scratch from a shrapnel bullet in front of the left ear, which scarred over in a few days. The soldier said, however, that the bullet had gone through his skull and a few hours after his wound said he could not see. Sent to the hospital he continued to say he was blind and finally brought up in an asylum for the blind near Lyons where he was taught to cane chairs and to write in Braille. This happened in July, 1915.

In October he was sent to the Hospital at Quinze-Vingt where a diagnosis of hysterical amaurosis was made with a large interrogation point. He was then sent to Brequet where there was a section reserved for disciplinary cases and very nervous cases not wanting to get well, a service under the charge of Roubinowitch.

The soldier escaped with a comrade and eventually reached Val-de-Grâce where the diagnosis of hysterical amaurosis was again made. Examinations several times showed that there was nothing abnormal about the eyes except that the eyelids presented habitual fibrillary movements (antebellum).

The eyelids passively opened, would remain open for a few minutes and then close. There was no winking of the eye to a light, yet the pupil preserved its reflex power.

Vision was abolished, however, the soldier said. He was without any other motor or sensory disorder. Much sympathy was given to the poor blind soldier. People were much astonished when the chief of the ophthalmological service had the man isolated in a dark room. Three weeks later the man had begun to see the light a little. A week later the eyes remained open without the necessity of having the lids raised by the fingers, and vision returned.

Re amaurosis, Parsons explains the blindness which may remain after consciousness returns following Shell-shock, as a condition in which the lower visual paths are carrying on their functions normally. For example, the pupillary reactions are preserved. The condition is not unlike that found in amaurosis of uremia, and Parsons has found it in children with posterior basic meningitis. For Parsons, therefore, the block occurs in the higher centers above the thalamus, possibly in the synapses of the optic radiation fibers. Ormond states that the true cases of concussion blindness invariably pass through phases of great discomfort; whereas the malingerers are without such discomfort. Medical suggestion, also, has a powerful effect here, and may actually retard recovery.
