Sister diagnosed with FD 6 weeks ago. BG down to about 200, but we're still working on it with vet. Lost weight early on but has regained it. She acts pretty normal now. She tends to squint an eye, one or the other about twice a day. There's no leaking or wetness and the vet has checked the eyes... said that her eyes looked great. But she continues to squint and sometimes wipes her face with paw. My question is... do you think the squinting is connected in any way to the diabetes?
