Differential Diagnosis & Pitfalls
- An infected corneal ulcer (, ) can also lead to a localized opacity, but the eye is usually inflamed with considerable conjunctival injection.
- In rare cases, perforation with an amniocentesis needle or trauma during forceps delivery can cause a corneal scar.
- An ocular dermoid (see ) has some similarities to the corneal scar in Peters anomaly but is usually elevated and is typically found at the limbus with extension posteriorly into the retrolimbal region.
