Third-century protrusion (prolapse, loss, film on the eye) — excessive protrusion of the 3rd century. The causes of the symptom are as follows:
- Soreness (ulcerative keratitis (Fig. 3 and 4), uveitis (Fig. 4), glaucoma (Fig. 5). often accompanied by lacrimation, blepharospasm (squinting), redness of the conjunctiva and other symptoms.
- Changes in the position of the eye in the orbit (enophthalmos, exophthalmos).
- Neurological: (Gorner’s syndrome (Fig. 1), dysautonomia, facial nerve damage, “Haws” syndrome in cats under 1 year).
In some cases, the protrusion of the 3rd century is mistaken for the prolapse of the lacrimal gland of the 3rd century (prolapse), but in this case it turns outwards, and does not “crawl” on the eyeball (Fig. 7).
As you may have noticed, this symptom occurs in various pathologies, respectively, and the treatment will be different. Some of these conditions are quite harmless (“Haws” syndrome, idiopathic Gorner syndrome), others, on the contrary, occur quickly and aggressively and can lead to loss of vision or the eye itself (corneal ulcer, uveitis, glaucoma).
Therefore, if you notice a protrusion of the 3rd century in your pet, you should immediately contact an ophthalmologist to make the correct diagnosis and prescribe the necessary treatment.
