Precis: 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:The purpose of this study was to demonstrate that visual field scores improve when the face masks are taped to prevent fogging artifacts.Methods: A 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 differ significantly in the examination with and without tape sealing [mean difference (without−with) 0.39 dB, 95% confidence interval: 0.07-0.70 dB, P = 0.018 and 0.49 dB, 95% confidence interval: 0.19-0.79 dB, P = 0.003, respectively]. There was no sequence effect (P = 0.967) for mean defect nor the square root of loss variance (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.
Im Mai 2020 stellte sich ein 76-jähriger männlicher Patient mit leichtem Fremdkörpergefühl an beiden Augen in unserer Ambulanz vor. Er gab keine Sehverschlechterung an. In der ophthalmologischen Anamnese bestanden keinerlei Auffälligkeiten in der Vorgeschichte. Im Rahmen der Erhebung der Allgemeinanamnese stellte sich jedoch heraus, dass der Patient im Dezember 2018 die Diagnose eines multiplen Myeloms von Typ IgA/Lambda erhalten hatte. Nach verschiedenen Vortherapien -darunter VRD (Bortezomib/Lenalidomid/ Dexamethason), autologer Stammzelltransplantation sowie Daratumumabwar Mitte April 2020 Belantamab Mafodotin eingeleitet worden. Es wurden 3 Zyklen von Belantamab Mafodotin verabreicht, jedoch musste die Behandlung Ende Mai 2020 aufgrund des Rezidivs eines Urothelkarzinoms abgebrochen werden.
