the upper lid, it shows tenderness. The tension
is not as strong; the pupil may be blocked with an exudate.

In the Sympathizing Eye.--There is an inflammation involving the choroid,
ciliary body and iris. There is pain, tenderness, small blocked pupil and
sight is poor.

[EYE AND EAR 355]

Course.--It usually appears between the third week and the sixth month
after the original injury. "The extreme limits are two weeks and twenty
years." The sound eye is likely to be attacked when the exciting eye is in
a state of active inflammation.

Treatment.--The "exciting eye" should be enucleated (taken out) before any
signs of sympathetic inflammation appears in the healthy eye. If it has
appeared, enucleation will be of no value; at all events if there is
vision in the exciting eye, the operation should not be done then.

INFLAMMATION OF THE RETINA FROM BRIGHT'S DISEASE (Albuminuric
Retinitis).--The retina is a very delicate structure and we are often able
to diagnose Bright's disease from the peculiar effect it produces upon the
retina.

Causes.--The cause is usually Bright's disease, (nephritis) and usually
the chronic Interstitial variety. Pregnancy causes it sometimes.
Interference of the vision, sight, is what the patient complains of. This
may be very slight, when you consider the great changes occurring in the
retina. Such patients are subject to attacks of temporary blindness of
uremic origin. The vessels of the retina are swollen and tortuous.
Bleeding and shining white patches are scattered through the back part of
the eye and a peculiar arrangement of glistening white dots around the
yellow spot. This disease shows itself late in Bright's disease and the
patient is not likely to live more than two years after the appearance of
this eye lesion.

Treatment.--It sometimes occurs during pregnancy. Then the question of
inducing premature labor arises. There is no local treatment that can be
of any use when it is caused by Bright's disease.

FITTING GLASSES.--This is done by lenses and prisms, etc.

Lens.--A lens is made of glass and prisms graded in strength, one surface
curved, and has the power of refracting or changing the direction of the
rays of light. A prism is wedge-shaped and bends rays of light towards its
base. A great many people are troubled with their eyes, much more than
years ago. We even see little children wearing glasses. It is unfortunate,
but true, that even more children and grown peop
