What is transistent cortical blindness?

What is transistent cortical blindness?

Brain vision loss: The eye sends information to the brain (occipital lobe) which computes the image we see as vision. If there is a disturbance to the function of this part of the brain, that is short term and returns to normal, we call it transient cortical blindness. This can be a circulatory problem, due to trauma or to some rare drug side effects. A neurologist can help you sort this out. ...Read more

Blindness (Definition)

Vision impairment and blindness are conditions in which a person cannot see well or see at all, even with glasses or contact lenses. If a person's best vision (with correction) out of either eye is only 20/70 - 20/200, he is impaired. If he can see no better than 20/200 or his visual field is no more than 20 degrees (severe "tunnel" vision), ...Read more

What causes cortical blindness (like examples) and what is it?

What causes cortical blindness (like examples) and what is it?

Multiple: The back part of your brain, the occipital lobe is what 'sees' images, your eyes are just fancy attenaes transmitting the image to your occipital lobe. If there is anything wrong with the cortex of your occipital lobe, this is cortical blindness. Stroke, migraine, seizures, tumors, all can be problems. ...Read more

What are the tests for cortical blindness?

What are the tests for cortical blindness?

A few: Cortical blindness is due to failure of the occipital lobe, the visual information processing center of the brain, to function properly. Many of these occur at birth. The eyes frequently are normal with normal pupillary reaction, yet the patient reports not seeing anything. There are tests of cortical electrical activity (vep) similar to an eeg which can register the lack of activity. ...Read more

What are the symptoms of cortical blindness?

What are the symptoms of cortical blindness?

Inability to see: Cortical blindness is loss of acuity due to damage to the occipital lobe of the brain. This can be a birth defect or an acquired vascular defect. If at birth, the child will show no recognition of the space around him, the eyes usually will dance (nystagmus) and will not track together. As an adult, the eyes cannot fixate, the pupils usually react to light but no vision will be reported. ...Read more

What is the treatment for cortical blindness?

What is the treatment for cortical blindness?

Generally none: Cortical blindness results from failure of the brain interconnections to the visual cortex to develop, or damage directly to the cortex from injury and vascular catastrophe. No treatment is possible. Such persons should be entered into programs for the blind and poorly sighted to develop alternate means of coping. ...Read more

What is the definition or description of: Cortical blindness?

Brain blindness: The occipital lobe and the optic connections to it allow for the making of images which we call vision. If these tissues are damaged by tumors or strokes, you can lose vision even though the eyes usually are normal. This is called cortical blindness. It sometimes occurs in newborns as a birth defect. ...Read more

Please let me know if there is any cure for cortical blindness?

None known: This is usually the result of a cerebral infarction in the visual part of the brain. Once the pattern of loss is established, the loss is permanent and no known treatment exists. ...Read more

Can pres cause permanent cortical blindness?

Can pres cause permanent cortical blindness?

Usually reversible: Posterior reversible encephalopathy syndrome (pres) is a syndrome characterized by headache, confusion, seizures and visual loss. There have been reported cases presenting with cortical blindness with near or complete recovery of vision. There are many implicated causes, including ecclampsia, malignant hypertension, tacrolimus and Cyclosporine use, hypercalcemia. Treatment depends on the cause. ...Read more

Is there any treatment advances for cortical blindness due to seizures?

Need clarity: Am not clear as to whether you have permanent cortical blindness, or episodic associated with seizure activity. If the former, this could represent permanency, but if paroxysmal, better seizure control is very probable, especially with newer medications, and potentially, a Vagal Nerve Stimulator unit. ...Read more

Hi doctors, can you tell me what is post-traumatic transistent cortical blindness?

Cortical Blindness: The term refers to a lesion in the occipital cortex of the brain which causes blindness, and implies no damage to the visual apparatus. Post- traumatic means that it is due to a trauma, most likely to the head, which caused the problem. Transient means that is not permanent, and it lasts only for a short period of time. ...Read more

Could someone get monocular cortical blindness from getting punched/slapped in the head?

L/R Hemifield: Monocular vision loss is not cortical, but the right (or left) side of the visual field can be impaired (hemianopsia or quadrantanopsia) from a cortical lesion in the occipital lobe of the brain. Physical trauma can be the cause of such brain damage, and in a child would be suggestive of abuse. A CT/MRI is the next test to correlate the visual field with the anatomy. ...Read more

No: You would faint doing this prior to any damage to your brain. Why would you try this anyway unless you have a fetish involvement in breath control which is in fact a dangerous activity.? ...Read more

What are some diseases that can cause blindness in children?

Many: Several eye problems can cause blindness in children. Fortunately, all are rather rare. Congenital (born that way) cataracts, lebers congenital amaurosis, albinism, amblyopia, congenital corneal diseases, genetic syndromes, congenital glaucoma, retinoblastoma, traumatic injuries etc all come immediately to mind. I'm sure an exhaustive list includes many other causes. ...Read more

How common is blindness in preemie children?

Blindness in preemie: Retinopathy of prematurity (rop) is a disease that affects immature blood vessels in the eyes of preterm babies. It can be mild with no visual defects, or it may become aggressive and progress to retinal detachment and blindness. As smaller and younger babies are surviving, the incidence of rop has increased. The incidence is inversely proportional to the gestational age of the infant. ...Read more

What causes blindness?

Long list: Blindness can be legal (20/200 or less) or absolute (cannot see light even). Eyes can inherit problems, get infected, traumatized and develop a host of diseases which can lower the vision such as diabetes, glaucoma, cataracts, macular degeneration, etc. Take your pick. ...Read more

Can adult blindness be cured?

Depends: What is the cause? Was the eye sighted earlier in life and developed vision loss? Was the eye injured or infected? Did it have surgery? Is there systemic disease.? So many questions: Ask your ophthalmologist for the answer and whether there is a possibility of vision to some degree. As you might guess some can be cured and others cannot. ...Read more

How common is blindness in the US?

Depends on level: Blindness can be defined in several ways. Obviously someone with no light perception in either eye is absolutely blind. The legal definition in most states is 20/200. Blindness can be caused by several inherited disease, diabetes, trauma and some infections. All of these can lower the vision. So how common, not too common but many are blind to various degrees. ...Read more
