[Some clinical aspects concerning diplopia after retinal detachment surgery with cryopexy and episcleral silastic sponge (author's transl)].

The aetiology of diplopia following retinal detachment surgery after the Lincoff-Custodis method is examined. Of 140 patients operated, 16 (i.e. 11.4%) developed diplopia. The authors believe that this diplopia is due to a fixation of the eyeball at the point of the silastic sponge placement. As responsible factors, which depend on the manner of sponge fixation and the size of the sponge, they regard: Alteration of the bulb curvature, shortening of the Tenon's capsule placed over the sponge, and changes in the conditions of muscular action.
