Try taking flaxoil a tablespoon or so once or twice by mouth daily...I use Barleans flaxoil as it is of great quality. You can find it many stores, but Fred Meyer also carries it in their Nutrition dept. in the refrig. section. Good flax oil needs to stay refrigerated.
This has been proven to help dry eye and is also good for your skin and many other things.
Good luck !
There is no treatment for the pattern dystrophy. The dry eye may also need mild steroids and treatment of minimal belpharitis if present (commonly is).
