It's been suggested that vision acuity improvements after CCSVI treatment could be due to a reduction of pressure in the eye.* Continuous intraocular pressure measurement with a contact lens sensor was safe and tolerable with repeated use, although mild adverse effects were common and the measurements were variable.
* Point out that with regard to efficacy, the device successfully delivered the full 24-hour pressure recordings in both sessions for 36 of the 40 patients.
I wonder if this could be captured using a product such as described in this article. 'Triggerfish' is on the market in Europe but not in the US. It would be fascinating to have baseline intraocular pressure measurements prior to CCSVI intervention, and measurements the day of the intervention, and measurements afterwards.
I had lasting vision improvements after my CCSVI procedure, and there are others who have as well.
Reduction of intraocular pressure could be a reason for people without MS to get treated for CCSVI.
