The third eyelid gland or the third eyelid, also known as the instantaneous membrane, is a semilunar conjunctival fold located in the inner corner of the eye, which is the normal eye structure of dogs. There is a flat T-shaped cartilage supporting the third eyelid, but no muscle tissue, which only makes the eye move passively when it is pulled by the eye muscle. The third eyelid gland is connected with the orbital fibroid tissue, which can restrict the movement of glands and prevent protrusion. Gland secretions reach the conjunctival surface through multiple catheters, producing 25% to 40% of the tear film, which is involved in protecting the cornea, removing foreign bodies on the corneal surface and immune function.
The third eyelid gland prolapse of a dog means that the gland is removed from the surface of the eyeball because the hypertrophy of the gland crosses the edge of the instantaneous membrane. In this picture, there is a red-looking polyp hanging on the corner of the dog’s eye, commonly known as cherry flesh, which is why many people call this disease “cherry eyes”. This “cherry flesh” is formed because of the rich distribution of instantaneous membrane blood vessels, excessive gland secretion will make the gland hypertrophy, but also because of the instantaneous membrane gland tube orifice is blocked by inflammatory products or foreign bodies to make the gland enlarged, across the free edge of the instantaneous membrane and prominent in the inner corner of the eye caused by the mass. The disease is common in small dogs, mostly in juvenile dogs, with no gender difference. However, it is common in American coca, Malchis, British bullfighting, Bakido, Bigger, Beijing Lion Dog, Sapi and Boston Terrier.
Cherry eyes are a common disease in ornamental sandpigs, such as raising sandpigs, etc. This disease has no obvious seasonal characteristics. For sandpigs, it may occur at the age of 2-16. In the inner corner of the lower eyelid of a Shapi dog, a small, fleshy dentate mass, pink (sometimes both eyes), grows in a short period of time and can grow to the size of a pea in three to seven days.
At the beginning of the onset of the disease, a large pink soft tissue mass of soybean appeared in the tear of the dog, one or both inner corners of the eye, and gradually increased. After a few days with eye drops, some may shrink back into the eyes, but in most cases the mass is only slightly smaller, the color becomes dark red, and the tear in the eyes is alleviated. Oral or local medication is ineffective. To recover completely, surgical treatment is needed.
The purpose of surgical treatment includes restoring the exfoliated glands to the anterior edge of the instantaneous membranes, maintaining the flexibility of the instantaneous membranes and preserving the integrity of glandular tissues and ducts. There are two methods of surgical treatment, including the third eyelid gland excision and embedding. The traditional method is excision, which can solve the problem of the third eyelid gland prolapse at one time, but it may cause dry eye after operation. Embedding can reduce the incidence of dry eye in later stage. According to foreign statistics, the incidence of xerophthalmia by embedding is about 14%, while the incidence of xerophthalmia by partial glandectomy is 48%.
Therefore, it is recommended that the third eyelid gland embedding be the first choice. If the recurrence occurs after embedding, excision is recommended. After the third eyelid gland resection, regular eye care and eye drops with tear components should be used, especially in elderly dogs. The best time for embedding surgery is one week after the onset of the disease. Early surgery can easily bleed due to acute inflammatory edema and aggravate inflammation of surrounding tissues. If the gland is not operated or operated too late, it will be exposed for a long time and cause conjunctiva, cornea and instantaneous membrane congestion and edema. Dogs with ocular discomfort also scratch, with the prolongation of the course of disease, often secondary conjunctivitis, keratitis, corneal turbidity or ulcer and affect visual acuity, serious blindness will also be caused. Therefore, in the early stage of the disease, we need to wear Elizabeth Ring and use anti-inflammatory eye drops every day to help alleviate the discomfort of the dog’s eyes and prevent secondary injury. Surgical treatment can be performed one week after the onset of the disease.
The cherry eye disease will also be cured if the sanddog is treated in time. And the best way to treat this disease should be surgery. So far, there has been no recurrence of swelling after surgery. Of course, if you want to treat cherry eyes for a sanddog, you have to choose a professional pet hospital. You can’t just operate on a pet dog.
If the eye problem is not treated in time, it will affect its normal life in the future. Cherry eye disease is not a very dangerous disease, but if it is not treated in time, serious people will threaten the life safety of Shapi dog. The sick Shapi dog is very pitiful. Its body and mind are very sad. We are it. All of life, in order to keep it away from eye diseases, we need to take care of it carefully from now on.
