My wife recently had back surgery in Nov of 2010 to remove 2 badly herniated disks and perform a fusion of L4/L5. Her recovery was going very well until 5 weeks post-op when she developed severe headaches and naseau. This continued for several weeks until we found out that she had a CSF leak. She wen't back into surgery mid-Jan 2011 to fix the leak in the dura. The seal seems to be working as the headaches have been gone for the last 2 weeks. During the time before her second surgery, she started to develop blurred and double vision. I have read that this can be a side effect of the CSF and also could be due to medications (even though she didn't have blurred vision from meds after the first surgery, so I doubt its that). Now that the CSF leak is fixed, it seems her eyesight is still verry blurred. We saw an eye doctor and her prescription in both eyes has changed dramatically. If her vision issues are due to the CSF, can we expect them to resolve themselves over time and if so in what timeframe (weeks, months, etc...). I guess I'm concerned that her CSF has caused permanent eye damage. Is this a possibility?
