Prevention and treatment of corneal thickening with white spot amniotic keratitis

Amniotic keratitis, also known as liver heat transmission disease, is one of the common eye diseases in sheep, mainly caused by trauma, chemical stimulation and bacterial infection of corneal epithelium of sheep eyes. The symptoms and prevention methods of amniotic keratitis are introduced as follows:

Sheep

First, symptoms: mild keratitis, in oblique light irradiation, can be found that the corneal surface is rough, transparent surface is light blue or blue brown. If caused by trauma, punctate or striped scars can be seen. At the same time, sheep have pain, tears, shyness, blepharospasm, vision loss and other symptoms.

In severe cases, due to the expansion of inflammation, small gray infiltration spots can be seen on the cornea, and even gray-white cloud-like opacity can be seen on the cornea. With the prolongation of the course of the disease, the cornea thickens continuously, showing a gray and clear-edged shell, and the surrounding neovascularization extends to it. When corneal ulcers occur, some or all of the vision is lost.

Do not herd sheep in the downwind where pesticides are sprinkled, so as to prevent the disease from blowing into your eyes. When driving out grazing, prevent whiplash and other mechanical injuries.

In order to prevent iris synechia, pupil dilation with 1 / 2% atropine eye drops can also be used intermittently with satisfactory results. For severe keratitis, a mixture of penicillin, 1% procaine and hydrocortisone can be injected subcutaneously under the bulbar conjunctiva or extraocular horn every other day with good results.
