Eyes
The most remarkable symptom in this region is the great tendency to stare, with wide open, often glassy eyes and with loss of thoughts and blank staring. Unable to avert the eyes from the object the patient is staring at; cannot recognise anything with staring, open eyes, letters disappear; the head sinks slowly down with the staring, but still the pupils remain fixed at the same point, thus coming to lie almost behind the upper lids; can be aroused from this state with effort (shouting, etc.), but sinks immediately back into that staring, absent- minded condition; or is aroused by an internal jerk or start, but sinks back again. The pupils may be first contracted and then much dilated, but more frequent is a great dilatation without reaction to light. There may also be an intense photophobia.
Many other disturbances of vision: sudden obscuration, with vertigo, as if by absence of mind; double vision, and objects seem to be of black colour, a state that may alternate with hardness of hearing; wavering of objects, to and fro, or approaching and receding, with vertigo and a desire to hold on tightly to something; letters seem to turn over when reading, and they are, also in candle light, surrounded by a halo of rainbow colours. These symptoms may be accompanied by some burning in the eyes, headache above the orbits, morning agglutination of the lids and the appearance of blue margins around the eyes. Strabismus, usually strabismus convergent, if periodic and of a spas¬modic character, or caused by convulsions. Strabismus caused by a blow to the eye.
Twitchings and spasms around the eyes; especially trembling and twitching of the lids. ‘Twitching in the circular muscle below the lower lid.’
Protrusion of the eyes during convulsions.
Ears
Difficult hearing; hears well only if one talks loudly ‘into her’ and in addition draws her attention to it. The difficulty in hearing may alternate with diplopia and a perception of objects as black.
Hardness of hearing in old people. This may be accompanied by a bursting sound, like a detonation, in the (right) ear on swallowing.
On the other hand, in many cases oversensitivity to noise is characteristic;
