Patients with vestibular and ocular motor disorders often perceive oscillopsia, diplopia or visual hallucinations as their chief complaint. However, they often struggle with verbalizing these subjective ocular motor and visual-perceptual signs precisely, which complicates a correct diagnostic classification of the suspected pathogenic mechanism.
In this multinational and cross-cultural feasibility study, a novel pictogram-based scale of 10 common ocular motor and visual-perceptual symptoms (called Pictogram Ocular Motor and Visual-Perceptual Symptom Scale, POVSS) was developed and validated. Healthcare professionals with or without expertise in neuro-ophthalmology and neuro-otology, representing a broad range of nationality and primary languages, were asked to match pictograms with medical symptoms (specialists) or a simple English symptom description (non-specialists).
A total of 174 participants (112 specialists, 62 non-specialists) from 30 nationalities evaluated the POVSS. On average, specialists reached a score of 9.7 out of 10 (SD = 0.5; 95% CI: 9.6-9.8) in matching symptoms and pictograms. Non-specialists achieved a mean score of 7.9 (SD = 2.3; 95% CI: 7.3-8.5) in accurately matching pictograms to simple English descriptions. In the specialist group, all pictograms met the common ISO quality standards, whereas in the non-specialist group, 8 out of 10 met the standards. While a significant difference in performance was found between the two groups, success rates did not differ between male and female participants.
Visual-perceptual symptoms originating from common vestibular and ocular motor disorders could be reliably identified using the POVSS by healthcare professionals, independent of participant nationality, or gender. Further research is needed to test the clinical applicability of the POVSS in different patient care settings.
患有前庭和眼动障碍的患者通常将视振荡、复视或视幻觉作为主要诉求。然而，他们往往难以准确表述这些主观的眼动和视觉感知症状，这使得对疑似致病机制进行正确的诊断分类变得复杂。
在这项跨国跨文化的可行性研究中，开发并验证了一种基于象形图的新型量表，用于评估10种常见的眼动和视觉感知症状（称为象形图眼动和视觉感知症状量表，POVSS）。邀请了具有或不具有神经眼科和神经耳科专业知识、代表广泛国籍和主要语言的医疗保健专业人员，将象形图与医学症状（专家）或简单的英文症状描述（非专家）进行匹配。
来自30个国家的174名参与者（112名专家，62名非专家）对POVSS进行了评估。平均而言，专家在症状与象形图匹配方面的得分为9.7分（满分10分，标准差=0.5；95%置信区间：9.6-9.8）。非专家在将象形图与简单英文描述准确匹配方面的平均得分为7.9分（标准差=2.3；95%置信区间：7.3-8.5）。在专家组中，所有象形图均符合常见的ISO质量标准，而在非专家组中，10个中有8个符合标准。虽然两组之间在表现上存在显著差异，但男性和女性参与者的成功率没有差异。
医疗保健专业人员可使用POVSS可靠地识别源自常见前庭和眼动障碍的视觉感知症状，且不受参与者国籍或性别的影响。需要进一步研究以测试POVSS在不同患者护理环境中的临床适用性。
