Side 163 - The diseased gland was found, on examination, much larger than a walnut ; it presented, on the surface, which had been turned towards the eye, three considerable eminences, or lobes, with deep fissures between them ; it was almost as firm as, but more elastic, than cartilage. A section of the gland exposed several small cartilaginous cysts, which contained a glairy fluid, and the interspaces consisted of a firm fatty substance traversed by a few membraneous bands.
Side 23 - ... continued, if necessary, by repeated touches with the scissors, until that part of the eyelid containing the tarsal cartilage is perfectly free, and is evidently not acted upon by the fibres of the orbicularis muscle, which lie upon it.
Side 23 - IB to be desired to refrain from making any effort whatsoever, and the surgeon is to wait until he sees that the lids are perfectly quiescent. A small narrow knife, or one blade of a blunt-pointed scissors, is then to be introduced close to the external angle, and a perpendicular incision made, of from a quarter, to half an inch in extent, or of a sufficient length to render the eyelid quite free ; the quiescent state of the lids, and especially of the orbicularis muscle, enabling the surgeon to...
Side 497 - All pressure is now to be removed from the eyeball, and the cornea knife gently withdrawn. The consequence of this is, that a portion of the aqueous humour escapes, and the iris falls into contact with the opening in the cornea, and closes it like a valve. A slight pressure must now be made upon the superior and nasal part of the i-yfi.
Side 338 - ... have left all the parts in their natural situation; in which cases I have hardly ever known them fail of dissolving so entirely as not to leave the smallest vestige of a cataract.1* In a few instances, where I have had fair opportunity...
Side 498 - ... of the left hand, till at length by an Occasional and gentle increase of the pressure, or by varying its direction, the iris gradually protrudes, so as to present a bag of the size of a large pin's head.
Side 23 - I recommend, as equal to the cure of the worst oases, is to be performed in the following manner : — • The head being properly supported, the eyelids are to be gently separated ; the patient is to be desired to refrain from making any effort whatsoever, and the surgeon is to wait until he sees that the lids are perfectly quiescent. A small narrow knife, or one blade of a blunt-pointed scissors, is then to be introduced close to the external angle, and a perpendicular incision made, of from a...
Side 374 - ... has been consigned to blindness for at least the first eight years of its existence, as a less evil than the hazard of an operation at so tender an age. The efforts of nature in disease are seldom stationary, and even when they fail to accomplish the cure, the correctness of the intention may be clearly discerned : thus in the congenital cataract, after the crystalline lens is converted into an opake substance, it is gradually absorbed ; and in proportion to the progress of absorption, the anterior...
Side 26 - ... everted, when they are to be fastened as directed. In order to prevent any attempt at union but by granulation, or a filling up of the incision, the edges are to be slightly touched with the sulphas cupri ; the eye and eyelids are now to be carefully cleansed ; a piece of lint, spread with the unguentum cetacei, is to be placed upon them ; a small compress is to be put under the edge of the eye-bone and orbit ; a retaining bandage covers the whole, and completes the different steps of the operation....
Side 7 - ... formation, or from an accidental or too luxuriant growth of the cilia. 2. The relaxation of the integuments, or a partial paralysis of the levator palpebrae, in a natural and otherwise healthy state of the eye and eyelids, are not primarily concerned in the formation of entropium, and never alone give rise to it; although, if other derangement take place, they may (by removing some power of resistance to it) assist in its more complete formation. 3. That, in a general or complete inversion of...
