—Develops slowly; no pain; normal pupil or slightly dilated; little or no injection of vessels and long duration; usually shows punctate deposit on posterior surface of cornea; aqueous humor cloudy; ends without adhesions or serious effects. Treatment expectant, hygienic and constitutional, according to causes found.
—Pain pronounced; onset rapid; pain referred to frontal and other branches of fifth pair, worse at night; circumcorneal injection, photophobia and lachrymation; pupil contracted; iris discolored and engorged, may be nodules upon its surface; exudation of lymph and iritic adhesions follow.
