CYCLITIS.
This is described by Möller as occurring in the domestic animals, but he fails to furnish instances of its diagnosis during life, and it is not likely to be often recognized in the living animal. Beside the usual signs of iritis, there is extreme tenderness to pressure around the anterior border of the sclera, increase of intraocular pressure, followed later by its diminution, and a cloudiness of the anterior portion of the vitreous humor. This last condition can only be detected by a full illumination of the vitreous, and its examination with the ophthalmoscope. It is quite liable to be complicated by suppuration and to go on to panophthalmitis.
The treatment does not materially differ from that of iritis, yet atropia must be used with caution as it is liable to increase the suffering. The preparations of mercury have been especially recommended.
