Corneal edema with dislocated anterior polar cataract

To report an unusual manifestation of anterior polar cataract.

Observational case report. A 35-year-old woman presented with localized inferior corneal edema associated with a white nodular lesion on the iris. The anterior lens capsule was deficient centrally with scrolled edges and an underlying subcapsular opacity. The nodule was removed surgically and subjected for histopathologic examination.

The histopathologic examination of the white nodular lesion showed parallel collagen fibers that were positive for collagen on the Masson trichrome stain. Correlating with clinical features, these findings were suggestive of dislocated anterior polar cataract.

Anterior pyramidal cataract may dislocate spontaneously and present as an anterior chamber foreign body and may even lead to corneal endothelial cell loss.
