RESUMO
Keratitis treatment outcome is usually dependent on the targeted treatment of the cause. We want to present a small corneal ulcer of unidentified origin that progressed into corneal melting and resulted in corneal perforation. The patient had a widespread antibacterial and fungal treatment and an ophthalmological follow-up with slit-lamp examination and AS-OCT. The spontaneous iris plug in the cornea helped to solve the anterior chamber collapse and made permanent anatomical changes in the anterior part. A 45-week follow-up found a hyperdense stromal corneal scar with 556-µm-wide stable iris-cornea contact and BCVA of 0.8. As a result, an iris plug in the cornea after corneal perforation can have a positive effect on healing and lead to good visual outcome.
