Non-organic vision loss (functional vision loss) is suspected when there is a visual disturbance (diplopia, reduced visual acuity or constricted visual field) but there is no detectable dysfunction of the ocular structures. The low vision provider encounters patients with non-organic vision loss and may be the first to determine the visual disturbance is indeed non-organic. However, functional vision loss is not a diagnosis of exclusion positive findings are required to make the diagnosis. Non-organic vision loss can be categorized as deliberate (malingering, factitious disorder) or non-deliberate (somatization, conversion disorder). This course is designed to provide the low vision provider with the knowledge and skills necessary to better determine if the visual disturbance is indeed non-organic, which category it falls under and how each can be appropriately managed.Learning Objectives:1. Describe non-organic vision loss and the different categories.2. Utilize specific exam techniques that will aid in determining if the visual disturbance is non-organic.3. Appraise how to appropriately manage the patient with non-organic vision loss. |
