CASE: II[.(For notes of this case I am indebted to Mr. Lloyd-Owen.)E. S. was thrown off his bicycle and received a slight wound in the region of the left external angular process.He was unconscious for about an hour.Three months later his left vision was little more than perception of light, and that only on the nasal side.The temporal field was lost up to the point of fixation.The optic disc was atrophic, and the retinal arteries smaller than those on the right side.The right eye was normal and field of vision full. CASE IV.H. A. fell off his bicycle and struck his right temple.Six months later his condition was as follows:Right eye: Atrophy of the optic nerve, with some narrowing of the retinal arteries.Visual field contracted to within IOO of the fixation point on the temporal side.R V. = i8 + .50D.Left eye: Normal; field of vision full.L V. = + .soD. CASE V.E C., a miner, was struck by a " coal tub" on the left side of fore- head and face one month before his admission to the Birmingham Eye Hospital.There was no loss of consciousness; there was some bleeding from each nostril, and the left eye was hidden by swollen and ecohy- mosed eyelids.Four days later, when the swelling had subsided and he was able to open the lids, he found that the sight of the left eye was defective.On admission there was a large scar involving the outer third of the left eyebrow, and with two other smaller scars, one at the junction of the outer and mtddle third of the inferior orbital margin and the other on the left side of the bridge of the nose, showed the extent of the injury.The left pupil was very slightly larger than the right, and its reaction to light was very sluggish, but its associated and con- sensual reflexes were good.There was no interference with the motility of the eye.The optic disc was pale, the pallor being more decided on the temporal side.The temporal field was lost up to within Io deg. of the point of fixation (vide chart).L V. = Fingers at 2 metres.The right pupil was somewhat dilated (about so mm. in dull daylight).The direct and associated reflexes were brisk, but the consensual reflex was deficient.The visual field was normal.R.V. = f.This case being a recent one, is still under observation.
