Abstract

Purpose: To assess the reliability of automated visual field studies with neurological abnormalities and normal reliability indices that were inconsistent with the remainder of the neuro-ophthalmic assessment.

Methods: Retrospective observational study from the clinical practice of a neuro-ophthalmologist at a tertiary referral center.

Results: From 2230 patient charts, ten cases were identified that met the inclusion criteria. In eight of the cases repeat visual field testing had no reproducible abnormality. Four of these cases were concerning for a bitemporal or homonymous hemianopia. None of the patients, including the two cases with a reproducible defect, developed any convincing manifestations of an organic disease related to the visual field defect.

Conclusion: Our findings suggest that even marked neurological abnormalities on reliable automated visual field tests can be false. When the remainder of the neuro-ophthalmic evaluation is inconsistent with the test result, we recommend that clinicians attempt to immediately repeat the visual field study.

在神经眼科实践中，在技术上“可靠”的视野研究中确定的人工视野缺陷。

目的:评估与其他神经-眼科评估不一致的神经异常和正常可靠性指标的自动视野研究的可靠性。方法:回顾性观察研究从临床实践神经眼科医生在三级转诊中心。结果:从2230例患者的病历中，筛选出10例符合纳入标准。其中8例重复视野检查无可重复性异常。其中4例与双颞或同质性偏视有关。所有患者，包括2例可再生缺陷患者，均未表现出与视野缺陷相关的器质性疾病的任何令人信服的表现。结论:我们的研究结果表明，即使在可靠的自动视野测试中，明显的神经异常也可能是错误的。当其余的神经眼科评估与测试结果不一致时，我们建议临床医生尝试立即重复视野研究。

期刊介绍： Eye and Brain is an international, peer-reviewed, open access journal focusing on basic research, clinical findings, and expert reviews in the field of visual science and neuro-ophthalmology. The journal’s unique focus is the link between two well-known visual centres, the eye and the brain, with an emphasis on the importance of such connections. All aspects of clinical and especially basic research on the visual system are addressed within the journal as well as significant future directions in vision research and therapeutic measures. This unique journal focuses on neurological aspects of vision – both physiological and pathological. The scope of the journal spans from the cornea to the associational visual cortex and all the visual centers in between. Topics range from basic biological mechanisms to therapeutic treatment, from simple organisms to humans, and utilizing techniques from molecular biology to behavior. The journal especially welcomes primary research articles or review papers that make the connection between the eye and the brain. Specific areas covered in the journal include: Physiology and pathophysiology of visual centers, Eye movement disorders and strabismus, Cellular, biochemical, and molecular features of the visual system, Structural and functional organization of the eye and of the visual cortex, Metabolic demands of the visual system, Diseases and disorders with neuro-ophthalmic manifestations, Clinical and experimental neuro-ophthalmology and visual system pathologies, Epidemiological studies.
