Caverneous hemangioma - tremors
by dexter13, Feb 19, 2005 12:00AM
Hi,
I have a cavernous hemangioma in my brainstem, which has bled a few times. I had Gamma Knife surgery a while ago (in 1999 I think) but I have many residual effects.
My questions.....
I have ocular palatial tremors, which makes it difficult to focus my eyes. Is there anything I can do to lessen or eliminate these? They seem to have gotten wroswe in the last few weeks...should I be concerned or is that normal?
Thanks!

Oculopalatal myoclonus is caused by damage to the dentato-rubro-olivary nerve connections in the brainstem. The symptoms can start anywhere up to several years after an injury to the brainstem.
It causes Oscillopsia which I think is what you are describing - difficulty focusing the eyes on one target due to the constant movement. I could be made transiently worse by fatigue, illness etc as the brainstem is a very metabolically active structure and is sensitive to changes in metabolism is already compromised.
Unfortunately it is very difficult to treat. Some eye specialists have done surgery on the eye muscles to reduce the movements to some success. Some have done Botox injections into the eye muscles to reduce movements. Drug therapies can be tried to reduce the activity in this area eg anti-cholinergics like Artane, but have side effects and the response is limited.
You should check with your ophthalmologists if any of these treatments are available to you
