Corneal Ectasia After Scleral Buckling Surgery

PURPOSE:To describe a case of corneal ectasia with marked asymmetric progression attributable to encircling buckle surgery for retinal detachment. METHODS:Case report. RESULTS:A 72-year-old man developed clinical signs of pellucid marginal degeneration in 1 eye after placement of an encircling scleral buckle. The fellow eye showed normal slit-lamp examination, with topographic signs of forme-fruste pellucid marginal degeneration. CONCLUSION:Patients with forme-fruste pellucid marginal degeneration may show progression and clinical manifestations after encircling scleral buckle, probably by changes in ocular physiology and corneal biomechanics.
