My pet was diagnosed with granulomatous marginal blepharitis. What is it?

The picture did not attach, so I do not have that information, but we commonly see eyelid margin tumors in older dogs. These are most commonly benign meibomian gland tumors. I am attaching a link with more information below. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=2463 I would recommend having your vet examine this and determine if it is causing a problem and should be surgically removed. Good luck! I hope that was helpful. Thanks for using PetCoach.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing her allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. This could also be due to something like mites and that can be easily determined with an exam and basic cytology which your veterinarian can perform. There are medications such as Apoquel or prednisone which may help with the itch. 

There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. 

Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). 

If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests.

 Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

Poor Gomez! From the picture, he has bletharitis- inflammation of the eyelid. I would recommend that you take him to a veterinarian. They will do an exam and try to find out the cause. They might do diagnostics such as cytology to see if infected. After that- they will give you meds that are safe for the eye area! Good Luck!

Oh goodness! Poor Gizmo! Often looking under the microscope at a quick smear of the fluid from the lesion can give your veterinarian a good idea if eosinophilic complex is possible. If the cells do not support that diagnosis then a biopsy may be recommended. Often these lesions also have a secondary infection so often I use antibiotics as well as steroids to resolve the lesions. Often a hypoallergenic diet may also be helpful. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

CT, MRI, and spinal tap can sometimes diagnose GME, but not all the time. The prognosis is very poor, even with every treatment available. Steroids are used at very high doses to try to decrease the inflammation, but there is no one cure for every patient.

The most common tumors that we see along eyelid margins are tumors called Meibomian Gland tumors. I am attaching more information about them below. http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=2463 These tumors are generally benign, but as you have seen can bleed and can also irritate the eye. It is generally recommended to remove them when they are small since it can often be done without general anesthesia. If they continue to grow, the surgery will be more invasive. So, I would recommend having your vet examine Moxley and decide what treatment will be best for him. Good luck! I hope that was helpful. Thanks for using PetCoach.

Hi there and thank you for using Pet Coach to address your concern. From the pictures you have provided, I would suspect several possible causes. A skin infection (bacterial or fungal), immune mediated disease such as lupus or pemphigus foliaceous, skin mites such as demodex or allergies. Due to the several possible causes that require testing to rule out, I would suggest having Weber examined by a veterinarian to have certain tests performed to determine what the primary cause is in order for Weber to receive the most appropriate treatment. I hope this helps! Please let me know if you have any other questions or concerns. I am available by phone or text based consultation if needed.
