Very commonly they have undergone a change of figure, most frequently a flattening which reduces them to scales, as in the epidermis and the epithelium. B. Simple, translucent, homogeneous solid, such as is found at the back of the cornea, or forming the intercellular substance of cartilage. C. The white fibrous element, consisting of very delicate, tenacious threads.
In the early stage of this malady there is an unnatural and often terrific brightness of the eye; but the cornea in distemper is from the first rather clouded. In rabies there is frequent strabismus, with the axis of the eye distorted outwards.
But it appears from dissection, that the tympanum is not the immediate organ of hearing, but that like the humours and cornea of the eye, it is only of use to prepare the object for the immediate organ.
The next day nearly 200 of the men were affected with partial or total blindness. Some had merely a sensation like fatigue of the visual organs, with heaviness, watering, and inflammation of the conjunctive membrane. But with others the pain was acute, the eye much inflamed, and the cornea covered with minute ulcerations.
Suddenly her lids, which had been closed, came open with a snap, as if an electric shock had passed through her, and the eyes, wild in their brightness, stared directly at me. And what eyes they were! The membrane grew red and redder until it was of the color of blood, standing out in frightful contrast with the transparency of the cornea.
There was complete anesthesia of the right eyebrow and of both eyelids and of the right cheek for an uncertain distance below the lower eyelid. The conjunctiva of the right eye became congested, and a small ulcer formed on the right cornea, which healed without much trouble.

And what eyes they were! The membrane grew red and redder until it was of the color of blood, standing out in frightful contrast with the transparency of the cornea.
For the winders, however, it is certain that their work seriously affects the eye, and produces, besides the frequent inflammations of the cornea, many cases of amaurosis and cataract.
The third book of the Compendium opens with several chapters on the anatomy and physiology of the eye and the phenomena of vision. The conjunctiva 2. The albuginea or sclerotic 3. The cornea 4. though the definitions are not in all cases quite clear and definite.
This is thought to be a defect in development. The changes that occur in the tissues of the eye appear to be largely due to the stretching consequent on the more or less uniform distentions of the globe as a result of hypertension. Cornea. Fissures occur in Descemet's membrane. Anterior Chamber. This is very deep in the greater number of cases. However, this rule has many exceptions.
