Visual loss describes temporary or permanent reduction in visual acuity and/or field. Its aetiology is diverse due to the contributions of the different neuro-ophthalmic structures (eye, optic nerve, and brain) to image formation and perception, but may be categorised into ocular causes (corneal, lenticular, vitreoretinal and macular) or optic neuropathies. Clinical evaluation of visual loss relies on thorough history and examination to guide further tests. In this article, we provide a practical overview of visual loss assessment for general physicians.
视力丧失描述了视力和/或视野的暂时或永久性下降。由于不同的神经眼科结构（眼睛、视神经和大脑）对图像形成和感知的贡献，其病因多种多样，但可分为眼部原因（角膜、晶状体、玻璃视网膜和黄斑）或视神经病变。视力丧失的临床评估依赖于详细的病史和检查来指导进一步的检查。在本文中，我们为普通内科医生提供了一个关于视力丧失评估的实用概述。
