Seite 332 - It is now about fifteen months since a similar affection occurred again to myself, without my being able to assign any cause whatever, or to connect it with any previous or subsequent indisposition. The blindness was first observed, as before, in looking at the face of a person I met, whose left eye was to my sight obliterated. My blindness was in this instance the reverse of the former, being to my right (instead of the left) of the spot to which my eyes were directed; so that I have no reason to...
Seite 332 - In this instance the loss of sight was towards my left, and was the same whether I looked with the right eye or the left. This blindness was not so complete as to amount to absolute blackness, but was a shaded darkness without definite outline. The complaint was of short duration, and in about a quarter of an hour might be said to be wholly gone ; having receded with a gradual motion from the centre of vision obliquely upwards toward the left.
Seite 309 - But we know that this is not the case. We know that we can see objects perfectly distinctly at different distances, within certain limits.
Seite 62 - ... the eyeball, was, however, practically little felt. Having determined that the disease was not seated in the anterior segment, and thus per exclusionem, and from the nature of the subjective symptoms (together with the objective symptoms presented by the anterior segment, and by the eye considered as a whole), referred it to some part of the posterior segment, we were in a position to conduct our treatment of the case, not with less efficacy at least than can be done now, when it is possible,...
Seite 62 - ... the uniform red field formed by the more vascular choroid. At the entrance of the optic nerve, which appears whitish-yellow and well defined, the retinal vessels are seen emerging. The retina in the situation of the yellow spot, is little or not at all vascular, and sometimes presents a greenish-gray aspect. A streak of pigment deposit may be seen at some part or all round the border of the optic papilla. The principal morbid appearances in the retina which have been observed are congestions,...
Seite 50 - ... her lap, its head may be received on the towel, and between the knees of the surgeon, and thus held steadily. The nurse now confines the arms and hands of the child, whilst the surgeon, having dried the eyelids with a soft linen cloth, proceeds to separate them by applying the point of the forefinger of one hand to the border of the upper eyelid, and the point of the thumb of the other hand to the border of the lower; and then sliding them against the eyeball, but without pressing on it, towards...
Seite 350 - What would be the visual effect of simultaneously presenting to each eye, instead of the object itself, its projection on a plane surface as it appears to that eye?
Seite 70 - For the examination of the eyes in children, especially when affected with intolerance of light and blepharopasmus, considerable management is required, and even some degree of gentle force. The surgeon is to seat himself on a chair with a towel, folded long-ways, laid across his knees. On another chair, on the surgeon's left hand, and a little in front of him, the nurse, with the child, sits in such a way that when she lays the child across her lap, its head may be received on the towel, and between...
Seite 324 - ... that they are situated in different planes, one behind the other, " that they never mingle with one another so as to change the order in which they stand before the eye, but the pearly spectrum always appears the nearest, then the sharply-defined insulo-globular, then the obscurely defined globules, and farthest away the watery threads.
Seite ix - Eye," says the author in his preface, •'< which should serve at once as a text-book for students and as a book of reference for practitioners, has been the great aim of the author in composing this manual. Accordingly, besides carefully discussing the principles, he has laboured to give such a practical exposition of the subject as will be found available at the bedside of the patient, and in the operating room.
