Heteronymous bilateral field defects
Clinical Classification Guidelines
Inclusion Terms
- Heteronymous hemianop(s)ia
Medical Intelligence & Overview
Heteronymous bilateral field defects refer to visual impairments affecting the outer halves of both eyes’ visual fields, a condition classified under ICD-10 code H53.47. Often known as heteronymous hemianopsia, this visual impairment is typically caused by neurological issues involving the visual pathways in the brain. The condition can impact daily life and activities requiring full visual perception, such as reading or driving. Recognizing the symptoms, causes, and available diagnostic methods is essential for understanding this condition.
Causes & Symptoms
Clinical Causes: Stroke or cerebrovascular accidents affecting the visual pathways in the brain Brain tumors pressing on or damaging the visual pathways Traumatic brain injury that affects the occipital lobes or optic radiations Multiple sclerosis causing demyelination of visual pathway fibers Surgical damage or complications involving the brain or neurological structures Infections or inflammatory diseases impacting the nervous system Cerebral ischemia caused by atherosclerosis or blood clots
Key Symptoms: Loss of vision in the outer half of the visual field in both eyes, often on opposite sides Difficulty perceiving objects on the affected sides of the visual field Challenges with reading or navigating environments due to impaired peripheral vision Possible bumping into objects or individuals on the affected sides Compensatory head movements to bring the peripheral visual field into view In some cases, preserved central vision with loss of peripheral awareness
Diagnostic & Treatment
Diagnosis Path: Diagnosis of heteronymous bilateral field defects involves a combination of clinical assessment and diagnostic tests:
Treatment Protocols: Management of heteronymous bilateral field defects focuses primarily on addressing the underlying neurological cause, along with supportive strategies to optimize visual function:
