Upon examination there could be found no disorder of the internal organs. Neurologically there was blinking, vasomotor excitability, slight reddening of the face, and dermatographia. An expert in ophthalmology confirmed the existence of a homonymous defect in the fields of vision. This defect could not be influenced by suggestion or by any other treatment, nor did any other change whatever occur in the condition.
Steiner inquires whether this hemianopsia is to be taken as organic or functional. The air-pressure of the shell hissing past might have produced a concussion, or the falling unconscious might have produced a commotio cerebri or a slight hemorrhage. The tic-like blinking and vasomotor excitability, however, suggest functionality.
Hysterical pseudoptosis.
Case 438. (Laignel-Lavastine and Ballet, January, 1916.)
Laignel-Lavastine and Ballet present a case of what they term hysterical pseudoptosis in a patient who showed no signs of organic disease of the nervous system, and moreover no special mental disorder. This soldier, 30 years of age, working in the auxiliary service, suffered from a troublesome lowering of his left upper eyelid. He went to the front in February, 1915. Aside from suffering a few mild and temporary blindnesses (éblouissements), he was entirely well up to the time of being wounded, March 18, 1915, by a bullet in the arm, and a bullet occasioning a superficial and slight wound 2½ centimeters above the middle of the left eyebrow. About three years later, a shell burst near him and made a large contusion about the right eye, without hurting the globus. He was then evacuated to Châlons-sur-Marne, and there remained for 48 hours, totally blind, probably on account of spasmodic closure of his eyelids. He then began to be able to use the left eye, which remained, however, very photophobic. A fortnight later, the wounds were healed, but the patient found himself unable to open his right eye. Three months later he returned to his dépôt, and left for the front October 24.
He was reëvacuated November 4, as unsuitable for service. He was then examined by an ophthalmologist at Chartres, who found a very mobile right pupil and a slightly atrophic right papilla; vision ½; left eye normal; vision ⅔; total paralysis of right levator palpebrae superioris without contracture of orbicularis. There was also paresis of the left upper lid, which ceased when the right eye was closed. The right half of the face was anesthetic, but there was no corneal anesthesia.
November 15: Right eyebrow lower than left; if the head was moved backward, the right eyelid followed the movements, and in this position there was no ptosis.
November 16: Analgesia in the super- and sub-orbicular region. November 17: frontalis and orbicularis functions normal.
