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.
