Amblyopia - Studies show a supplement helps

I've been hearing a lot lately about alternative treatment for amblyopia including nutritional supplements. So, I did a bit of googling and thought I'd share what I found on the topic. I would love to hear from parents who are using CDP-Choline or vision professionals.

Study: Effect of oral CDP-choline on visual function in young amblyopic patients.

RESULTS: The addition of CDP-choline to patching therapy was not found to be more effective than patching alone after 30-day treatment. The present results showed that adding CDP-choline to patching stabilised the effects obtained during the treatment period. In fact, whereas the participants treated only with patching showed a decrease in visual acuity at 90 days, these receiving CDP-choline and patching combined appeared to maintain the results obtained (two-way ANOVA: P = 0.0042). Similar results were obtained when measuring visual acuity by isolated Snellen's E letters.

CONCLUSIONS: In amblyopic patients, CDP-choline combined with patching contributes to obtaining more stable effects than patching alone.

From Vision International:

Concerning the supplement for amblyopia, CDP-choline has been proved effective in treating conventional amblyopia by two scientific studies. The scientific name of CDP-choline is cytidine-5′-diphosphocholine, which is an important component of cell membranes all over our body and has the role of keep our body form and function well. An Italian study has proved CDP-choline enables people with amblyopia to have shorter time to improve their vision. According to the research, with 500 milligrams of CDP-choline everyday, children at the age of 5 to 9 can improve their vision in 10 days, while it takes 1 month for children to improve their vision by wearing eye patch.

But this does not mean CDP-choline is perfect for everyone with amblyopia. As a matter of fact, CDP-choline is similar to soy lecithin. If children are unluckily allergic to soy, it is often the case that they may be also allergic to CDP-choline. Besides, though it is effective to treat amblyopia, this does not mean people can take as much as possible. Researches show if CDP-choline is taken too much, it will result in gas and diarrhea.
