Mouth-nose masks impair the visual field of healthy eyes |pdf=|usr=}}{{33983986}} gab.com Text Mouth-nose masks impair the visual field of healthy eyes JO: PLoS One http://www.kidney.de/pget.php?&tw=1&pmid=33983986 #FOAvip BACKGROUND: Mouth-nose masks have been requested to prevent the transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The aim of the present study was to investigate, if wearing a mouth-nose mask impairs the visual field function in normals. METHODS: Thirty eyes of 30 subjects were recruited for the present study. White-on-white perimetry (OCTOPUS 900; 90 degrees ) was done and sensitivity was analysed in 14 defined test points (P1-P14, inferior visual field) under 3 different test conditions while the subjects were wearing a mouth-nose mask: (I) 1.5 cm under the lower eyelid, nose clip not used (position1.5cm_no_clip); (II) 1.5 cm under the lower eyelid, nose clip correctly positioned (position1.5cm_with_clip); (III) 0.5 cm under the lower eyelid, nose clip correctly positioned (position0.5cm_with_clip). All data were compared to sensitivity without wearing a mouth-nose mask (reference). Mean Delta was calculated, being the difference between the results of each test condition and reference, respectively. RESULTS: Sensitivity was significantly different between position1.5cm_no_clip and reference at 10 test points (p<0.05). Sensitivity at test point P7 was significantly different between position1.5cm_with_clip and position0.5cm_with_clip compared to reference (p<0.001), respectively. Mean Delta increased while wearing a mask at P7: position1.5cm_with_clip (-8.3 dB +/- 7.3 dB) < position0.5cm_with_clip (-11.3 dB +/- 9.5 dB) < position1.5cm_no_clip (-20.1 dB +/- 7.6 dB). CONCLUSION: Visual field function was observed to be significantly impaired in the inferior-nasal sector while persons were wearing a mouth-nose mask, especially when the nose clip was not correctly used.
