Abstract
Purpose:
Pellucid marginal degeneration is a noninflammatory thinning disorder typically involving the inferior cornea. We describe a patient with superior corneal thinning similar to classic pellucid marginal degeneration.
Methods:
An 80-year-old man was evaluated for high astigmatism.
Results:
The right superior cornea had a prominent band of thinning with ectasia. Both inferior corneas had characteristic zones of thinning without inflammation.
Conclusions:
Superior pellucid marginal corneal degeneration should be considered in the differential diagnosis of superior corneal ectatic disorders.
