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.
