    4 TWO CASES OF UNILATERAL TEMPORAL HEMIANOPSIA. Unilateral Temporal Hemianopsia, with Central Scotoma of the other Eye. Col. N , aged sixty-six, a retired officer of the army, was first seen in consultation by me on June 28th, 18S4, and gave the following history : In the summer of 1849, while at one of the military posts on our western frontier, he was struck by lightning while standing at the door of his tent. He fell to the ground and remained unconscious for several hours. When he regained his consciousness, he discovered that he was blind in both eyes, but this condition rapidly im- proved, so that at the end of a few days he had regained his sight, and in a short space of time had the perfect possession of all his faculties. He remained perfectly well in every re- spect till 1857, nearly eight years later, when the muscles of the left thigh and leg began to atrophy, and almost simul- taneously there suddenly appeared a temporal hemianopsia of the right eye. The paresis and atrophy of the muscles of the left lower extremity slowly but steadily progressed till 1859, since which time there has been no change. There has been no change in the field or in the acuity of vision of the right eye since the hemianopsia first appeared. He walks with comparative ease, but the muscles of the left leg are markedly smaller than those of the opposite side, and he easily becomes fatigued. In December, 1883, or about six months before I saw him, he noticed a central obscuration of vision of the left eye, which came on suddenly, and this scotoma has existed
