This is shown by a diffuse inflammatory infiltration of the substantia
propria of the cornea. Part or whole of the cornea of one or both eyes
may be involved. Very fine blood vessels may invade the deep structures
of the cornea.
=Cause.=—Syphilis, tuberculosis, rheumatism, diabetes and rachitis are
systemic diseases found back of this trouble.
=Symptoms.=—Irritation, lachrymation, photophobia with ciliary
injection are the chief symptoms.
=Treatment= must be local and constitutional.
Locally atropine should be used. Dark glasses should be worn or the
patient must be kept in a dark room. Treatment to the trigeminal nerve
and tissues of the orbit should be given.
Constitutional treatment should be spinal with the idea of arousing all
the forces of the body to greater activity. Careful dieting should be
followed according to indications.
The infiltration and blood vessels will ultimately disappear. Sometimes
enough may remain to cloud the vision.
