Excerpt from Philadelphia Medical Times, Vol. 7: A Bi-Weekly Journal of Medical and Surgical Science; August 4, 1877 We observe here the consequences only of a morbid disturbance, without obtaining an insight into the real nature of the path ological process. Our situation here is the same as in many other cases of amaurosis or amblyopia which are produced by other morbid conditions of the human body. Here, too, the connection between cause and effect now and then completely escapes our observation. I have in my mind the so-called pseudo-amaurosis, without any characteristic ophthalmoscopic evidences. In these cases, too, certain molecular changes in the nerves are doubtless the primary cause of the blindness. If the origin of such blindness is obscure, just as obscure and inexplicable remains as yet their course. For we cannot give any reason why in one case after a longer or shorter duration the amaurosis completely disappears, and vision returns, and why in another case total blindness is produced or vision is but partially restored.
