... I now present 28 specimens showing the changes which take place in the globe after certain injuries, and which render the removal of the eye necessary, either to relieve pain or to prevent loss of sight in the other eye.
Although the question regarding the propriety of removing the globe can seldom give rise to doubts in the minds of an experienced practitioner, there are rare instances when the exercise of the most deliberate and wise judgment is requisite.
In general terms, it may be stated that the injuries which most frequently necessitate the removal of the globe are: 1st, foreign bodies within the intraocular tissues ; 2d, concussions ; and 3d, incisions, especially near the ciliary region.
In general terms, it may also be stated, that an eye should be extirpated, whenever, after an injury, the inflammation, especially of the iris and choroid fails to improve after a reasonable time, and there continues a tenderness on gentle pressure near the corneal border, with loss of vision.
Foreign bodies in the globe.--Of the specimens before you, 13 represent cases in which foreign bodies were lodged within the globe. In three of these cases, pus had formed in the vitreous humor, after a period varying from three days to three weeks. In four cases there was atrophy of all the ocular tissues, so that he sclerotic was deeply fissured in the region of the four rectimuscles, and firmly contracted upon quite a hard mass of atrophied vitreous, choroid and retina. In six cases you perceive excellent examples of every stage of detachment of the retina; in some the retina resembles an umbrella partially closed; in two cases it has been pressed into the central portion of the globe, presenting the appearance of a cord passing from the optic nerve to the anterior part of the eye...
