Visual field loss after stroke. Spontaneous visual field improvement can occur poststroke but in varying degrees. This has been reported in up to 50% of patients, usually within the first 3–6 months. After this period spontaneous recovery is possible, but usually at a much slower rate.5.
9 Σεπ 2013 · Occipital and parietal lobe strokes most commonly caused visual field loss. Treatment options included visual search training, visual awareness, typoscopes, substitutive prisms, low vision aids, refraction, and occlusive patches. At followup 15 patients (7.5%) had full recovery, 78 (39%) had improvement, and 104 (52%) had no recovery.
4 Ιαν 2022 · This paper demonstrates a multi-modal approach using brain imaging (MRI) to carefully characterize the link between perimetry-derived visual field loss and biological markers of stroke damage.
27 Μαρ 2021 · Homonymous visual field defects represent the most frequent type of visual field loss after stroke, affecting nearly 30% of individuals with unilateral post-chiasmal brain damage. This review aimed to gather the available evidence on the biomechanical changes to visual field loss following stroke.
Visual impairment after stroke impacts quality of life and leads to loss of independence and depression. 1 2 Vascular occlusion along the afferent or efferent visual pathways can produce myriad effects, including transient monocular vision loss (TMVL), visual field deficits or ocular dysmotility.
4 Νοε 2019 · A range of interventions exist: these are proposed to work through restitution of the lost visual field; compensation via behavior changes; substitution using a device or extraneous modification; or assessment/screening, ensuring diagnosis and treatment.
Blindness is a common sequela after stroke affecting the primary visual cortex, presenting as a contralesional, homonymous, visual field cut. This can occur unilaterally or, less commonly, bilaterally.
