This disease is chiefly confined to children. The child scarcely can bear the light, the lids are spasmodically closed, and the head constantly turned away from the light. The eye is not very red, but a few of the large vessels are considerable injected. It is very liable to recur, and may prove obstinate, and cause ulceration of the cornea.

TREATMENT. -- In this disease it is very important that the general health should be looked after. The local treatment before advised should be resorted to, and the constitutional treatment should be very active and energetic.
