What's the difference between Horner's Syndrome and Haws Syndrome?

Within the last few days, I have noticed that Belle's 3rd eyelid is showing in both eyes- it will show for a few hours, then go away, then come back. Her eyes also look a little "sunken in". She seems normal otherwise - she acts like she can see fine, she's playing, eating, etc. I have been researching Horner's Syndrome and Haws Syndrome, and it appears to me like this is what she has, but I'm not sure of the difference between the two? One of them says that the 3rd eyelid showing can be due to parasites or intestinal upset, but Belle never leaves the house and her poops look normal. Anyone know anything about Horner's and Haws Syndromes?

    I have only heard about Horner's syndrome and that is usually just one eye and is caused by trauma to the facial nerve or other head trauma. Kira had it briefly after surgery to remove a polyp from the back of her throat. And she was expected to have it after the facial trauma of having a bullae osteotomy but somehow my surgeon managed to avoid injuring her facial nerves even to his own surprise. I was just reading about Haws and it mentions dehydration along with the causes you just mentioned. Either syndrome itself is not a problem, but both are the SIGN that there is a problem so I would give the vet a call.

    Haws syndrome can be caused by parasites bit I think those are rare in the US. When Jester had her 3rd eyelid of her left eye showing and I took her to an opthalmic specialist vet they realised I was originally from England and I told them that I'd brought Jester to the US with me. But she'd been here (Oregon and California) for 10 years so they ruled that out. Horners syndrone is caused by damage/pressure to the sympathetic nerves and usually only affects one side. Unfortunately Jester had a thyroid cancer and it was pressing on the nerve in the left side her neck which was causing the horners syndrone as a side effect. From the symptoms I doubt Belle has Horners syndrone as that usually only affects one side. Haws syndrome may be a possibility but I think its more likely that there is an underlying mild illness that is making her 3rd eyelids show up. Take her into the vets for a check up to see if they can confirm the cause and provide any treatment she needs.
