ABSTRACT
PRCIS: Tape sealing of the face mask can prevent fogging artifacts of visual field testing. Here we demonstrate that tape sealing can improve visual field scores even when fogging artifacts are not obvious.
PURPOSE: To demonstrate that visual field scores improve when the face masks are taped in order to prevent fogging artifacts.
METHODS: Single-center, randomized 2×2 cross-over study. Twenty-six visual fields of 13 patients of the glaucoma outpatient clinic were included. Patients were randomized in either sequence 1 (Octopus visual field examination without tape sealing, followed by examination with tape sealing) or sequence 2 (examination with, followed by without tape sealing).
RESULTS: The results for mean defect and square root of Loss Variance (sLV) differ significantly in the examination with and without tape sealing (mean difference (without-with) 0.39▒dB; 95% CI: 0.07 to 0.70▒dB; P=0.018 and 0.49▒dB; 95% CI: 0.19 to 0.79▒dB; P=0.003, respectively). There was no sequence effect (P=0.967) for mean defect nor sLV (P=0.779). A significant effect for period (P=0.023) for mean defect was yielded.
CONCLUSION: Tape sealing of face masks during visual field testing prevented fogging artifacts and improved visual field scores even when fogging artifacts were not obvious, and should be considered in clinical practice.
