Why is my vision deteriorating?

Have you had a cat scan or an MRI? I have seizures, and they have affected my eating, walking, etc... I also have problems in my head ( nerve damage, calcium growth o n my brain, and continuous bleed). Before I have to have my head drained (short story- had a omaya reservoir put in to drain off the blood that aculates) my vision in my left eye gets blurry like I am wearing dirty gles, but I am not even wearing gles. After the draining, my eye gets better. You may need to go back to your neurologist for the MRI or cat scan. Also migraines are not all hereditary, they can be brought on by certain foods you eat.
