Objetivo: Avaliar a influência de máscara facial de proteção, recomendada na pandemia de COVID-19, durante o exame de perimetria visual.
Métodos: Foram recrutados participantes de ambos os sexos, com idade superior a 18 anos, e sem histórico de antecedentes oftalmológicos importantes. Todos foram submetidos ao exame de perimetria visual computadorizada (HFA II-i 750 SITA -Standard) em ambos os olhos. Os índices de confiabilidade e os índices globais de desempenho foram analisados. O hemicampo visual inferior do gráfico total deviation de todos os olhos foi numerado para identificação dos pontos com alteração. A acuidade visual apresentada para longe foi registrada. Os participantes mantiveram o uso da máscara facial de proteção classe PFF2 durante os procedimentos.
Resultados: Foram incluídos 14 participantes (28 olhos), sendo 9 mulheres (64,29%), com média de idade de 25,85(±9,04) anos, variando de 20 à 53 anos. Todos os exames apresentaram bons índices de confiabilidade. As médias dos indicadores de desempenho do exame foram visual field index (VFI) = 99,14±1,01%, mean deviation (MD) = -0,34±0,87 dB, pattern standard deviation (PSD) = 1,62±0,47 dB, perdas de fixação (PF) = 3±0,04%, falso positivos (FP) = 0,89±1,47%, falso negativos (FN) = 0,79±1,50%, acuidade visual apresentada (AV) = -0,05±0,09 logMAR, equivalente esférico (EE) = -0,91±0,99 DE e tempo de duração = 4,51±0,53 min. Apresentaram redução de sensibilidade 16 olhos da amostra estudada (57%), conforme demonstrado pela análise dos gráficos total deviation. Os três pontos com maior frequência de redução da sensibilidade foram P13 (6 olhos), P10 e P20 (5 olhos) e P12 (4 olhos).
Conclusões: O uso da máscara facial de proteção, recomendada na pandemia de COVID-19, durante a perimetria visual pode reduzir a sensibilidade do hemicampo inferior, sem afetar os índices de confiabilidade do exame. A supervisão constante do examinador é fundamental para a detecção de artefatos relacionados ao uso da máscara.
Purpose: To evaluate the influence of protective face mask, recommended in the COVID-19 pandemic, during the visual perimetry examination. Methods: There were recruited participants of both genders, aged over 18 years, with no significant ophthalmologic and systemic history. They were underwent standard automated perimetry examination (HFA II-i 750 SITA - Standard) in both eyes. Reliability parameters and overall performance were analyzed. The inferior hemifield from total deviation plot was enumerated to recognize impaired points. Visual acuity presented for distance was recorded. Participants maintained the use of the class PFF2 protective face mask during the procedures. Results: Fourteen participants (28 eyes) were enrolled, 9 women (64.29%), mean age 25.85(±9.04) years (range: 20-53). All exams showed good reliability parameters. The means of the exam performance indicators were visual field index (VFI) = 99.14±1.01%, mean deviation (MD) = -0.34±0.87 dB, pattern standard deviation (PSD) = 1.62±0.47 dB, fixation losses (FL) = 3± 0.04%, , false positive (PF) = 0.89±1.47%, false negative (FN) = 0.79±1.50%, visual acuity (AV) = -0.05±0.09 logMAR, spherical equivalent (SE) = -0.91± 0.99 (sph) and duration = 4.51±0.53 min. Sixteen eyes of the sample studied (57%) showed reduced sensitivity, as demonstrated by the analysis of the total deviation plot. The three points most frequent of sensitivity reduction were P13 (6 eyes), P10 and P20 (5 eyes) and P12 (4 eyes). Conclusions: The use of face mask, recommended in the COVID-19 pandemy, during visual perimetry examination can reduce the sensitivity points of the inferior hemifield, without affecting the reliability parameters tests. Constant monitoring by the examiner is essential for the detection of artifacts related to face mask.
