Wedge scleral buckling in prevention of fish mouth phenomenon in retinal detachment surgery.

ABSTRACT

Wedge scleral buckling done in 45 eyes of 43 patients with ballooning detachment and large horseshoe tears where fish-mouth phenomenon was anticipated pre-operatively is analysed. In all of the cases, the retinal break settled on the wedge buckle after drainage of sub-retinal fluid and there was no radial retinal folds over the buckle nor was there fish-mouthing of the tears. The final success rate was 89%. There were no significant operative or post-operative complications and in none of the cases was there extrusion of implant or infection.
