Purpose:
To describe a case of de Quervain tenosynovitis triggered by the repetitive performance of intravitreal injections.
Methods:
Case report of a 32-year-old ophthalmologist.
Results:
The ophthalmologist experienced de Quervain tenosynovitis while performing 425 intravitreal injections a month. These were predominantly performed in condensed sessions (injection clinics). Symptoms resolved with nonsurgical management.
Conclusion:
The repetitive performance of intravitreal injections may be an unrecognized occupational hazard for ophthalmologists.
