The author cannot but concur with Schmidt-Rimpler that the results reported by Deutschmann, though surprising, cannot shake his opinion that the retina is detached by exudation from the choroid. Thus far Samelsohn's proposition, to treat detachment of the retina by diaphoresis, decubitus, and pressure-bandage for three or four weeks (or longer), promises the best results. All operative methods of treatment that have hitherto been tried are to be deprecated. Those implicating the retina and vitreous are most fraught with danger, whereas paracentesis of the subretinal space by a puncture of the sclerotic and choroid is least prejudicial. The prophylactic and curative treatment of the primary difficulty, the uveitis, remains of paramount importance.
