Clinical approach to vision loss: a review for general physicians
Antony Raharja et al. Clin Med (Lond). 2022 Mar.
Abstract
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.
