Color vision deficiency (CVD) is an under-reported problem among medical personnel, and its impact is still not well characterized. We aim to assess the impact of CVD among ophthalmologists on the accuracy of diagnosing different benign and malignant choroidal lesions.
This is a cross-sectional study conducted on ophthalmologists. We used a web-based survey to collect responses through professional ophthalmology society social media. The survey included a set of five images for normal fundus, choroidal nevus, circumscribed choroidal hemangioma, choroidal metastasis, and choroidal melanoma, wherein each image simulated the three main types of CVD: protanopia, deuteranopia, and tritanopia, in addition to a non-simulated image.
Forty-one participants were included, with a mean age of 40 (±9.2) years. They were 28 (68%) men and 13 (32%) women. Participants showed significantly low accuracy for definite diagnosis for circumscribed choroidal hemangioma, nevus, melanoma, and metastasis when the images simulated protanopia and deuteranopia, but not tritanopia. Nevertheless, participants maintained the capability to recognize the nature of the lesions for both simulated and non-simulated images if they were benign or malignant, thereby ensuring immediate referral for specialized care. The exception was with simulated choroidal nevi images, wherein participants incorrectly assigned simulated protanopia and deuteranopia nevi images to malignant lesions.
Protanopia and deuteranopia affected the accuracy of diagnosing several choroidal lesions; however, ophthalmologists with those two simulated CVDs were still able to discriminate between benign and malignant tumors.
色觉缺陷（CVD）在医务人员中是一个报告不足的问题，其影响仍未得到充分描述。我们旨在评估眼科医生中CVD对诊断不同良性和恶性脉络膜病变准确性的影响。
这是一项针对眼科医生的横断面研究。我们通过专业眼科学会社交媒体使用基于网络的调查问卷来收集回复。该调查问卷包括一组五张图像，分别为正常眼底、脉络膜痣、局限性脉络膜血管瘤、脉络膜转移瘤和脉络膜黑色素瘤，其中每张图像除了一张未模拟的图像外，还模拟了三种主要类型的CVD：红色盲、绿色盲和蓝色盲。
纳入了41名参与者，平均年龄为40（±9.2）岁。其中男性28名（68%），女性13名（32%）。当图像模拟红色盲和绿色盲时，参与者对局限性脉络膜血管瘤、痣、黑色素瘤和转移瘤的明确诊断准确率显著较低，但模拟蓝色盲时并非如此。然而，如果病变是良性还是恶性，参与者对于模拟和未模拟的图像都保持识别病变性质的能力，从而确保立即转诊接受专科护理。例外情况是模拟脉络膜痣图像，参与者将模拟红色盲和绿色盲的痣图像错误地判定为恶性病变。
红色盲和绿色盲影响了几种脉络膜病变的诊断准确性；然而，患有这两种模拟CVD的眼科医生仍然能够区分良性和恶性肿瘤。
