Very good article. But I believe there may be a missing link between Gastroparesis and related malabsorption and its impact on vision. My research has led me to believe that cataract (clouding of the lens) formation is dependent on nutrition and antioxidant levels.
I've already checked my DNA report, and it does not indicate a genetic predispostion to the development of cataracts. But I do have multiple variants on genes involved in the Methylation Cycle, which seems to be the basis of my health problems, including the GI issues.
As a result I've developed a severe amino acid deficiency due to the malabsorption.
A recent visit to my opthalmogist has shown a doubling of cataracts in both eyes in about 9 months. This seems to correlate with my declining amino acid levels. So besides working to correct the malabsorption, I will be increasing my antioxidant levels in hopes of slowing down their formation.
Keep in mind, I'm not a Dr, just a regular person trying to put two and two together. I'd love to hear any feedback if anyone else has noticed a similar correlation.
