Experimental work on Lindner's scleral resection operation * suggested that the following factors play a significant role in bringing about reattachment of the separated retina:
The mechanical shortening of the scleral capsule, resulting in a diminution of the volume of the eyeball, so that a shrunken retina can reattach to the sclerochoroidal wall.
The inflammation of the choroid and sclera which follows the incisive operation, causing (a) a considerable subchoroidal exudation, which fills the suprachoroidal space, and (b) a mild subretinal exudation, the result of the inflamed choroid.
The suprachoroidal exudate acts most probably in two ways: mechanically, by further diminishing the choroidal volume, thus bringing the choroid nearer to the detached retina, and by inducing chorioretinal adhesions. The latter is facilitated by the subretinal exudation.
In summary, it was concluded that the mode of action of the scleral resection operation is the correction of a size discrepancy between
