Strumous, or asthenic ulcers ; 3. Serpiginous ulcers ; 4. Ulceration accom- panying disease of the palpebral conjunctiva, such as purulent ophthalmia, or granular lids. ]. A phlyctenule consists of a small yellowish-white elevation orTlhe surface of the cornea or the conjunctiva at or near the sclero-corneal margin. If on the cornea it tends to advance to- wards the centre, and a narrow leash of vessels runs to it from the margin. The phlyctenule consists at first of an accumula- tion of lymphoid cells immediately beneath the raised epithelium, and these may be absorbed without going on to ulceration, although very commonly the latter ensues. Ultimately a small mjbula is left, and the little band of vessels ceases to be per- vious, although its track may be recognised long afterwards by means of direct examination with the ophthalmoscope. Phlyctenular ulcers are usually accompanied by a fair amount of congestion of the eye ; often cause considerable photophobia, and show a marked tendency to relapse. Those occurring around the corneal margin are the most difficult to cure ; usually \—2
