Overview of Occipital Lobe Diseases

Occipital lobe lesions are more common in vascular disease and brain trauma, but brain abscesses and brain tumors are less common.

Its damage characteristics:

Ipsilateral hemianopia with binocular consistency;

with macular avoidance;

Ignore optic nerve atrophy and Wernicke's blind pupil stiffness;

Generally not accompanied by other neurological symptoms. Cortical blindness is a bilateral lesion above the lateral geniculate body, including lesions on both sides of the leaf and optic radiation.

Its clinical characteristics are :

Both eyes are completely blind;

Pupil photoreaction is intact;

The fundus is normal and the abnormal visual evoked potential (VEP) examination is helpful to distinguish it from pseudo-blindness and rickets. Disease Classification: Ophthalmology

Causes of Occipital Lobe Diseases

I. Other diseases caused by infection, such as exogenous fever, pneumonia, sepsis, dysentery, urinary system infection and other toxic encephalopathy caused by persistent state; caused by brain trauma, brain tumor, cerebrovascular disease .

Second, brain damage and brain damage. Occurrence of occipital lobe epilepsy due to viral infection, radiation exposure, or other causes during embryonic development; birth injury is also a major cause of occipital lobe epilepsy; traumatic brain injury can also cause occipital lobe epilepsy .

3. With the development of society and the improvement of health conditions, adult occipital lobe epilepsy caused by cerebral parasitic disease has decreased. The disease is mainly prevalent in North China, Northeast China, Yunnan and other places. As a result of eating food or water contaminated with worm eggs, the worm eggs enter the body, parasitize in the cerebral cortex with blood circulation, and cause adult occipital lobe seizures.

Fourth, other causes Food poisoning, drug poisoning, drinking, overwork, pregnancy, childbirth, etc. are the common causes of the occipital lobe epilepsy. ^[1]
