Question 1

what causes bitemporal heteronymous hemianopsia?

Accepted Answer

Chiasmal lesions: Most common is a lesion affecting the optic chasm. There are other causes...You need a full work up with MRI by your eye care physician to pinpoint exactly what cause may be. Please seek out care.

Question 2

doctors say bf is suffering with homonymous hemianopsia, its cause and treatment?

Accepted Answer

Stroke brain disease: Homonymous hemianopsia refers to a defect in the field of vision that is typically caused by a stroke or brain disease.

Question 3

can you please suggest treatment of homonymous hemianopsia?

Accepted Answer

Depends upon cause: Not uncommon for this to be due to stroke, but can be seen with any brain pathology affecting optic radiations or occipital lobe.  Treatment in case of stroke is best preventative, such as using anti platelet drugs, but once there is tissue damage, unusual for much improvement.  Unfortunately, no simple solution to reverse brain damage once established.

Question 4

i had a stroke due to an avm rupture three years ago which left me with left hemiplegia and left hemianopsia. i smoke weed, is this bad for me?

Accepted Answer

Limited data: There is limited and conflicting data regarding marijuana use and stroke recovery.  Some studies suggest there may be a benefit, while others show no such relationship.  Hence, there are no definitive recommendations that can be made.  However, there are data regarding the effects of smoking, which is quite clear - smoking is bad for you.  That much is clear.

Question 5

causes of bitemporal hemianopia?

Accepted Answer

Pituitary disease: Most losses in the bitemporal pattern - partial or complete - originate with tumors of the pituitary gland pressing on the optic nerve chiasm.  There are a few rare cases with this pattern from vascular malformations and tumors like meningioma.

Question 6

i was wondering what are the causes of bitemporal hemianopia?

Accepted Answer

Causes of bitemporal: Hemianopsia include pituitary lesions which can put pressure on the optic chiasm.  These lesions include adenomas, meningiomas, craniopharyngiomas, sarcoidosis, primitive neuroectodermal tumors (pnet), aneursymal enlargement of the anterior communicating artery, and sphenoid sinus destructive lesions with extension.  I hope this helps.  Well wishes.

Question 7

what is bitemporal epilepsy?

Accepted Answer

Both sides: Epilepsy where seizures arise from both temporal lobes in a person. (Not typically at the same time.)

Question 8

what is the role of pituitary in causing bitemporal hemianopia?

Accepted Answer

Proximity to optic: The pituitary gland sits immediately behind the optic chiasm which is where the optic nerves from each eye cross.  A pituitary tumor or other swelling there of can press on the optic chiasm and cause one to lose vision to each side.  Anuerysms of the anterior communicating artery can also do this.  Very cool question.  One would usually need an MRI of the brain to furhter investigate.

Question 9

how is visual acuity preserved in bitemporal hemianopia?

Accepted Answer

Nerve fiber pattern: Bitemporal  hemianopia is the classic later stage vision pattern in advancing pituitary tumor.  Generally the central fibers, which carry the best acuity are affected later in the condition.  A great deal of vision loss would have to be ignored by someone with this condition before the nerve fibers for the central acuity start to drop out.

Question 10

please help! what is the role of pituitary gland in causing bitemporal hemianopia?

Accepted Answer

Pituitary tumors: Hi. the optic chiasm (optic nerves; some of them cross sides) is right above the pituitary. Big pituitary tumors can push up out of the pituitary's bony pocket (the sella) and push against the parts of the optic nerves that cross (they see lateral/temporal visual fields) and cause bitemporal hemianopsia; the parts of the optic nerves that see the medial visual fields are spared.
