We have given tem-porary relief in thesecases by occasional tap-ping. Excision of the eye may be required; but this alternative shouldbe avoided if possible, on account of the inadequate support which anempty socket gives to an artificial Critchetts Operation for Staphyloma Comese. 558 DISEASES OF THE IEIS. Recent investigations with the aid of the ophthalmoscope have shownthat sclerotic staphyloma is not unfrequent in the region of the opticnerve, and that it is a frequent accompaniment of myopia. Occasionally, also, we meet with examples of a pretty general dis-tention and attenuation of the sclerotic coat, but which condition is notincompatible with a tolerably fair amount of vision. I have seen this total staphyloma continuing many years in both eyes without muchloss of sight. Total staphyloma is incurable, if we understand by a cure, a restora-tion of the eye to its normal size and form; and there is nothing butimprovement of the general health which is able to delay or to arrestits further progress.
