الملخص EN

Purpose.

To report a case with transient anisocoria after corneal collagen cross-linking (CXL).

Methods.

Case report.

Results.

A 24-year-old male underwent corneal collagen cross-linking (CXL) in his right eye for keratoconus.

At the end of the procedure, the pupil of the treated eye was irregular and dilated, while the pupil of the fellow eye was round, regular, and reactive (anisocoria).

The following day, pupils were round, regular, and reactive in both eyes.

Conclusion.

Anisocoria may be a transient and innocuous complication after CXL.

A possible cause for this complication might be the anesthetic drops used before and during the surgical procedure or/and the ultraviolet A irradiation during the treatment.
