The case is beyond question hysterical,—the phenomena consisting of an ophthalmoplegia externa, alternating with spasmodic contracture of the internal recti, associated with myosis and loss of light reaction. The influencibility of this situation during the process of tests, to say nothing of the other stigmata, clinches the diagnosis—an important one, since the development of an external ophthalmoplegia after occipital trauma might possibly be regarded as an organic disease due to hemorrhage in the region of the eye-muscle nuclei.
Sandbag drops on head: Internal strabismus and diplopia. Various diagnoses. Cure by lenses.
Case 436. (Harwood, September, 1916.)
A four-pound wet sandbag fell eight feet on the head of a sergeant-major, 28, lying in a Gallipoli dug-out, November 24, 1915. The sergeant-major was removed to Lemnos with headache and giddiness, and a week later developed bilateral internal strabismus with double vision and head noises. The diagnosis was “brain tumor” or “syphilitic meningitis of the base.” On the voyage home, the diagnosis was altered to “multiple neuritis or neurasthenia.”
He was admitted to the King George Hospital, January 1, 1916, unable to move the eyes outwards; they moved rather poorly up and down. There was a slight lateral nystagmus. The patient had been unable to read or stand since the accident. The visual acuity of each eye was less than 6/60, but with an arrangement of lenses he could get 6/5 with either eye. He had perfect binocular vision and could read ordinary type comfortably. In a week’s time he was able to stand without support and walk with a stick. Whenever he took off the glasses, the strabismus and diplopia immediately returned. Other combinations were tried but failed to relieve symptoms. The lenses given were +0.375 c. Vert. and L. +0.25 S. +0.25 C. 75 do.
Hemianopsia: organic or functional?
Case 437. (Steiner, October, 1915.)
A 19-year old volunteer, never ill (no nervous disease in the family), after a period of training went into the field, October 3, 1914. November 5, a shell struck the trench nearby but failed to explode. Up to that time everything had been quiet. The soldier had been looking out of the loophole, surveying the terrain. He felt a great fear, got a blow in the neck, fell down unconscious, remained unconscious for an unknown time, and later walked back with his comrades. About an hour later, this volunteer,—who was a very intelligent young man, possessing much knowledge of biology, including the nature of visual fields,—noticed a black spot in the field of vision, which came and went, but after a few hours remained continually without disappearing. Otherwise, there was no complaint except a feeling of dizziness when stooping.
