H47.612
Cortical blindness, left side of brain
Clinical Classification Guidelines
Medical Intelligence & Overview
Cortical blindness is a visual impairment caused by damage to the occipital lobe of the brain, which is responsible for processing visual information. When this area is affected on the left side of the brain, it can lead to blindness or severe visual deficits in the opposite visual field, typically the right side. This condition differs from eye problems because the eyes themselves are usually healthy, but the brain's ability to interpret visual signals is compromised. Recognizing the signs and understanding the underlying causes can help in the management of this condition.
Causes & Symptoms
Clinical Causes: Stroke affecting the occipital lobe, particularly on the left side of the brain Traumatic brain injury damaging the occipital cortex Brain tumors located in or near the occipital region Infections such as encephalitis or abscesses involving the occipital lobe Neurodegenerative diseases that impair brain function Rarely, seizures or cortical spreading depression impacting visual processing areas
Key Symptoms: Loss of vision in the right visual field, despite healthy eyes Difficulty perceiving visual stimuli on the affected side Preservation of eye movement and pupillary reflexes Possible visual hallucinations or illusions No problems with eye movement or focus, indicating a cortical rather than ocular issue
Diagnostic & Treatment
Diagnosis Path: Diagnosing cortical blindness involves a comprehensive neurological exam and specialized testing. The process may include:
Treatment Protocols: Management of cortical blindness focuses on addressing the underlying cause and supporting the patient's visual function. Some approaches include:
