Abstract:
Functional visual disorder (FVD) belongs to functional neurological disorder (FND), and clinical examination and testing are not consistent with clinical ophthalmic or neurological disease.The major clinical manifestations are visual acuity loss and visual field loss.FVD has a serious impact on patients' daily life, and it is difficult to distinguish from other visual disorders by its clinical manifestations. Some patients receive unnecessary treatments, so early diagnosis and accurate treatment are particularly important. This article reviews the clinical characteristics, pathological mechanism, diagnosis and differential diagnosis, auxiliary examination, management and prognosis of FVD in order to improve clinical diagnostic and therapeutic rates and patient prognosis.
