Abstract
Purpose
To report iatrogenic complications and to review the potential complications caused by noncontact tonometry (NCT) in related literature.
Methods
This case report describes two cases of active recurrent herpes simplex keratitis (HSK) on top of a thin corneal scar. The cornea was perforated by the air pulse from the NCT, resulting in an air bubble in the anterior chamber.
Results
Both patients were diagnosed with active recurrent necrotizing stromal HSK on top of a thinned corneal scar after previous therapeutic treatment involving tissue adhesive glue with a bandage contact lens (BCL) to treat a perforated cornea. During a follow-up visit, both patients reported similar symptoms of acute pain and fluid exuding from their eyes immediately after undergoing NCT. Slit-lamp examination revealed a perforated cornea with an intracameral air bubble. Treatment involved use of tissue adhesive glue and BCL in both cases.
Conclusion
NCT may not be sufficiently safe in patients with active infectious keratitis, particularly in cases where the cornea is relatively thin and necrotic.
