Question 1

what is transistent cortical blindness?

Accepted Answer

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.

Question 2

what are the tests for cortical blindness?

Accepted Answer

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.

Question 3

what are the symptoms of cortical blindness?

Accepted Answer

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.

Question 4

is there a cure for cortical blindness?

Accepted Answer

No: That's when you're brain can't process the information, and eye is usually fine.There is no treatement for this at this time.

Question 5

what is the treatment for cortical blindness?

Accepted Answer

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.

Question 6

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

Accepted Answer

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.

Question 7

what is post traumatic transient cortical blindness?

Accepted Answer

Blindness after bonk: Transient cortical blindness  - the name says it all.  This is blindness  which is temporary due to injury of the brain (not the eye) following trauma.

Question 8

cortical blindness with seizures. is any cure available?

Accepted Answer

Cure no, control yes: Control seizures and the cortical blindness will also be controlled.

Question 9

please tell me, could you develop cortical blindness from holding your breath too long?

Accepted Answer

Impossible: You would pass out before brain damage.

Question 10

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

Accepted Answer

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.
