ABSTRACT
PURPOSE:
The coronavirus (COVID-19) pandemic has changed how outpatient care is delivered in ophthalmology clinics, particularly with glaucoma care. This case series highlights the need for awareness of fogging and improper face mask fit as causes of standard automated perimetry artifacts in patients with ocular hypertension and glaucoma. CLINICAL PRESENTATIONS Six patients with the diagnosis of ocular hypertension, glaucoma suspect, or glaucoma underwent standard automated perimetry (24-2 or 10-2 SITA, Humphrey Field Analyzer) while wearing ear-loop surgical face masks. Due to patient complaints of fogging during the testing, low test reliability, and unexpected results, the tests were repeated after taping securely the mask to the bridge of the nose. CLINICALFINDINGS:
Fogging may reduce visual field (VF) test reliability and induce artifacts that mimic glaucomatous defects. VF test reliability can be improved and artifacts minimized following mask taping. In 1 case there was worsening of VF defects after mask taping. This suggests that fogging may also disguise true VF defects.CONCLUSIONS:
Fogging can result in unreliable VF testing with glaucoma-like artifacts. Secure taping of the face mask to the nose bridge may minimize this problem and reduce unnecessary additional testing and follow-up visits.
