Inclusion Terms
- Homonymous hemianopia
- Homonymous hemianopsia

Medical Intelligence & Overview
Homonymous bilateral field defects refer to visual impairments where the same half of the visual field is lost in both eyes. These deficits often result from neurological issues affecting the visual pathways in the brain. Such conditions can include homonymous hemianopia or quadrantanopia, impacting a person's ability to see parts of their environment and affecting daily activities.
Causes & Symptoms
Clinical Causes: Stroke or cerebrovascular accidents damaging the visual pathways in the brain Brain tumors that compress or invade visual processing areas Traumatic brain injuries affecting optic radiations or occipital lobes Multiple sclerosis causing demyelination of visual pathways Infections or inflammatory conditions impacting brain tissues related to vision
Key Symptoms: Loss of the same side of the visual field in both eyes, either half or a quadrant Difficulty seeing objects on one side, which may lead to bumping into objects or missing parts of the environment Problems with reading or writing due to missing sections of text Increased risk of accidents or falls because of visual deficits Potential awareness of only part of the visual scene, leading to disorientation
Diagnostic & Treatment
Diagnosis Path: Identifying homonymous bilateral field defects typically involves comprehensive eye examinations, including visual field testing how it is, using perimetry tests like automated perimetry or confrontational visual fields. Neuroimaging studies such as MRI or CT scans are crucial for locating the neurological cause, especially to visualize damages in the brain's visual pathways. Sometimes, neurological assessments are combined with ophthalmic evaluations to determine the extent and nature of the visual field loss.
Treatment Protocols: Stroke management, including medical therapy to prevent further events Surgical interventions for tumors or other structural issues Rehabilitation therapies, such as visual field expansion training or adaptive techniques in daily life Occupational therapy to help adapt to visual limitations Assistive devices like prisms or visual aids to improve functional vision
