H47.619
Cortical blindness, unspecified side of brain
Clinical Classification Guidelines
Medical Intelligence & Overview
Cortical blindness is a neurological condition characterized by a loss of vision caused by damage to the brain's visual processing centers, rather than any problem with the eyes themselves. Specifically, the condition associated with ICD-10 code H47.619 involves unspecified sides of the brain, meaning the exact location of the damage has not been specified but impacts the brain areas responsible for visual perception. People with cortical blindness appear blind, but their eyes may function normally. This condition underscores the importance of the brain's role in interpreting visual information.
Causes & Symptoms
Clinical Causes: Stroke leading to damage in the occipital lobe of the brain Traumatic brain injury affecting the visual cortex Brain tumors or neoplasms impinging on the occipital region Infections such as encephalitis or meningitis that involve the visual processing centers Neurological disorders such as multiple sclerosis that damage the visual pathways Cerebral hemorrhage impacting the occipital lobe Hypoxia or ischemia resulting from reduced blood flow to the brain Surgical complications involving the posterior brain regions
Key Symptoms: Complete or partial loss of vision despite healthy eyes Difficulty recognizing objects, faces, or colors Visual field deficits, such as blind spots or loss of peripheral vision Possible visual hallucinations in some cases No apparent eye abnormalities upon examination Difficulty with visually guided activities like reading or navigating spaces Preserved reflex responses to visual stimuli, despite lack of conscious sight
Diagnostic & Treatment
Diagnosis Path: Diagnosing cortical blindness involves a combination of neurological examinations and imaging studies. Healthcare providers typically perform:
Treatment Protocols: Currently, there is no specific cure for cortical blindness. Treatment strategies focus on managing underlying causes and supporting adaptation to vision loss. Approaches include:
