ART.VI.-Detachment of the Choroid | Operating Microscopes

This disease has till now been rarely observed with the ophthalmoscope.* By its means amore or less developed spherical prominence is seen in the fundus of the eye projecting into the vitreous body.

Its smooth surface is free from folds, and on the top of it are seen the retinal arteries and veins, beneath the retina we see the choroid, with its vessel and intervascular spaces.

The color of the prominence is yellowish, but it is sometimes modified by hemorrhage or deposit of pigment. Detachment of the choroid is distinguished from detachment of the retina by the immobility of the detached structures during movements of the eye.

The disturbance of vision is, as a rule, very great, and vision is ultimately entirely destroyed by separation of the retina.

The disease ends in irido-choroiditis, softening and atrophy of the ball.

Choroidal separation is due to an effusion of serum or blood between the sclerotic and choroid, or to the development of a tumor which has its origin beneath the choroid. In this last case, the affection is almost always accompanied, at one period or other of its course, with symptoms of glaucoma, which are entirely absent if the separation be due ro exudation or liquid effusion.

It may be admitted in general that this disease cannot be made the object of any special treatment, and that the indications are those of the primitive affection which causes it.
