    rosy zone of fine subconjunctival vessels ap- pears around cornea, radiating in parallel lines from its margin. Iris appears dull, blurred, and discolored (light iris becoming greenish, and dark one brownish-red), and its move- ments are sluggish. This is caused by hy- peremia and plastic effusion. Discoloration partly caused also by turbidity of aqueous humor from admixture with lymph or pus. Pupil contracted and its edges may become glued by exudation to ant. capsule of lens. Such adhesions are called posterior synechia [Gr. aw, together, and e^w, to hold]. They may not be detected until atropine is applied, when pupil dilates irregularly and shows ad- hesions at one or more points. When whole circumference of pupil is thus adherent con- dition is called exclusion of the pupil. When exudation encroaches upon area of pupil, con- dition is called occlusion of the pupil. In syphilitic iritis yellowish-red nodules, analo- gous to gummy tumors, may appear upon surface of iris. Sometimes exudation is chiefly serous; intra-ocular tension is in- creased ; there is less tendency to synechias ; pupil is dilated, and there is often a deposit of lymph-particles on post, surface of cornea. Condition is then called serous iritis, Desceme- titis, or aquo-capsulitis. Pain in iritis varia- ble ; may be very severe, and extend over forehead, temple, and side of nose {ciliary neuralgia), or may be entirely absent. Pho-
