I’m not an ophthalmologist, but I would suggest that your husband has his blood cholesterol levels checked, if this has not been done already.

Cholesterol deposits can occur anywhere in the body where fluid is present, therefore more common areas are within blood vessels. While most of these deposits are small, larger ones can impead blood flow, or break free and clog up smaller vessels which prevents nutrients getting to tissue and cells. These cells can then die, causing permant damage.

Lowering fat intake and becoming aware of the healthier types of fats (the good oils) can go along way to preventing potential cholesterol damage. Following the dietary advice your husband has been given will also help. Having a lower fat intake can also assist in weight loss and help control blood pressure.

High cholesterol levels are also influenced by genetic predisposition, so it is helpful to be aware of any issues our parents may have had.

Once your husbands cholesterol levels have been checked, his doctor may sugest medication to lower the blood levels, which will inturn lower cholesterol deposits.

There are a variety of OTC herbal compounds that are believed to assist with the regulation of cholesterol, including but not limited to lethicin and plant sterols. A reputable health food shop should be able to assist you, but make sure that you mention any medications or allergies that your husband may have.

I’m based in Australia, and some manufacturers of table margarines are now putting plant sterols in their product so that consumer’s can lower their cholesterol level. They are very effective, so check to see if these products are available in your supermarket.

Hope this helps.
