This is how Cassie's Left Eye looks most of the time. I can tell when the virus is flaring up when her eye turns from a brown haze to a thick blue cloud and looks irritated. I then have to treat her with terramyacin or gentocin 3 times a day untill it looks "normal" again. From what I have learned about the virus it is genetic. Cassie was the runt of the litter but they ALL had eye problems. Hers was actually the most promising. I believe she can see somewhat out of the eye, but she will never have perfect vision out of it.

This is the best she has ever looked. This was taken in the spring of 1997. Unfortunately, upper respiratory infections also are typical of cats who have the feline herpes virus. She is very prone to colds and URIs (Upper Respiratory Infections). Although, it is said that the Feline Herpes Virus is contageous, Neither of my other two cats have caught anything from her.

Upon my searches in the web I have found information about a test for the herpes virus. I have never had the test performed, since my vet felt it was unnecessary and was quite sure Cassie does infact have the disease. In case anyone would be interested in taking the test I will copy the info here:
TEST NAME: FVR/Calici Serology
PURPOSE OF TEST: Detection of antibody to feline herpes virus (feline viral rhinotracheitis virus) and feline calici virus.
DESCRIPTION OF TEST AND PROCEDURES: Serum neutralization (SN). The determination of the antibody titer that will neutralize the virus.
SAMPLES NEEDED AND PROCEDURES FOR SUBMITTAL: Submit 1-2 ml of blood in a sterile red top tube or serum on a cold pack. We prefer the clot be separated off before shipping.
SCHEDULE FOR RUNNING TEST: DAY(S) Tuesday and Friday TIME 12:00
SCHEDULE FOR REPORTING RESULTS: DAY(S) Friday and Monday (3 days) TIME 12:00
INTERPRETATION OF TEST RESULTS: Any titer of greater than or equal to 1:2 means that the animal has been exposed to the virus. NORMAL RANGES: 1:2 to 1:16.
SUPPLIES USED TO PERFORM TESTS: Tissue culture cells; medium with fetal calf serum; culture flasks; dilution of tubes; pipettes; multi-well plates; microscope; laminar flow hood; centrifuge; mechanical diluter; mechanical pipettor.
STAFF TIME REQUIRED TO PERFORM TESTS: The test takes approximately 4 hours of staff time on each of 2 occasions during the week.

I Found this interesting page: UPPER RESPIRATORY INFECTIONS/ FELINE MEDICINE

It has alot of useful information. I would reprint it here but there is too much.

I found this on a Medical Information page:
Feline herpesvirus FHV-1 (previously known as feline rhinotracheitis virus) can cause a variety of different clinical syndromes. The most common symptom is a runny nose and sneezing (rhinitis) which may be combined with reddened, squinting, runny eyes (conjunctivitis). FHV can also cause corneal ulcers, oral ulcers, fever, and diarrhea. In kittens, FHV infection can be severe. FHV is generally transmitted through direct contact or sneezing, and may be transmitted from a mother to her kittens before they are born. A vet will usually prescribe a broad spectrum antibiotic to clear up secondary bacterial infections, but there is no real cure for the viral infection, just management of it. As in human herpes virus infection, cats may develop a latent infection that causes virus shedding or mild recurrent attacks when the cat is stressed. If you know your cat has had herpes virus infection, try to keep your cat from getting stressed (when that's possible). If he is under stress, he can begin to shed the virus again without showing any signs of being sick himself, which means he may infect other cats. Note that FHV affects only cats. Don't worry, you can't get herpes from your cat!

More information I have found on the net on "Josh's Home Page -- the Ultimate Guide to Cats"
Feline Viral Respiratory Disease - All cats are prone to this disease. It represents colds and flus in humans, and therefore has been termed "Cat Flu". This term is incorrect however, because no feline flu virus has ever been found in Australia. Respiratory disease in cats can be caused by a wide variety of germs, but in more than 90% of cases, the cause is one of the two following viruses:- (1) Feline Herpes Virus which causes a disease called Rhinotracheitis that produces symptoms in the cat's nose and windpipe area, and (2) Feline Calicivirus which produces similar symptoms to that of Feline Herpes. Early signs include sneezing, coughing, discharges from the nose and eyes, and ulcers on the tongue and in the mouth. In severe cases loss of appetite accompanies these symptoms. Short-haired cats suffer the disease more severely than other cats. Although very few cats die of this disease, it continues for several weeks. Cats can also be vaccinated against this disease.

This is all the net-based information I have been able to find. But, I would like to say that Cassie is the most affectionate cat and she behaves like nothing is wrong. The only things I have to be cautious about is either her getting stressed and the virus acting up or her getting exposed to other illnesses. For instance, I took her to my vets office to get groomed, thinking if she stressed out and had a re-lapse she would be able to get instant medication. Well, the groomer is also the person who takes care of the kittens they adopt out. I went in to pet the kittens while she was being groomed and didn't know they had ringworm. He came in there and we were talking about the kittens when he mentioned the ringworm. I didn't think much about it at the time. I washed my hands thoroughly and felt that there was nothing to worry about. Well, with-in two weeks she came down with ringworm. She was COVERED with it from head to toe. Apparently, she caught it from either myself or the groomer since her immune system is compromised she was vulnerable. So, I suggest anyone who has a cat with FHV be very careful what she is exposed to.
