While all deliberate statements of Dr. Knapp are to be received with
the greatest respect, there may be danger of falling into a treacherous
security as regards the influence of ossified eyeballs for mischief. His
careful discriminations will certainly call attention to what are and what
are not dangerous cases ; but all surgeons know that one of the most
fruitful sources of sympathetic irritation of a healthy eye is ossification or
calcification in the other; and while the middle term undoubtedly is irido-
cyelitis, the pei-il is so urgent that a needless operation may well be
performed rather than risk a patient's only eye when an atrophied and
ossified bulb may Cabergoline 0.5 Mg be setting up trouble, which at its beginning is not very
well defined.

Pope, M. D., of New Orleans. [Archives for Oph. and Otol., ii., 1, 87.]
The operation suggested is designed for cases where only a peripheral
pupil is available, and to be most useful must be small. When there are
central corneal opacity, without or with iritic adhesions; prolapsus iridis,
especially with partial staphyloma cornetB ; diffused corneal opacity, most
dense at the centre; in case an eccentric pupil is needful, and the sphincter
is hard to dilate or adherent — in all these cases the operation is com-
mended as meeting important optical indications. The author has operated
six times, and says the Dostinex Online existence of a double pupil is not annoying, and, if
the new Dostinex Mg one is below, a habit of drooping the upper lid is soon acquired,
and covers the upper pupil. The mode of operating is by a yav^ small

wound, and witli small forceps seizing with their point the iris near its
periphery, and, dragging out only a little of it, cutting it closely with finely-
pointed scissors. A very small Order Dostinex Online opening can thus be secured, which can-
not be done if the pupillary edge is severed.
It seems likely that this suggestion may in some cases be worth
remembering.
82. — -TTie Treatment of Amaurosis and Amblyopia l>y Strychnia. By Dr.
Albeecut Cabergoline Tablets Nagel. fTiibingcn, 1871, pp. 141.]
Our attention is called, in this pamphlet to the hypodermic u?e of
strychnia. The method has been already known for a sufficiently long time
to permit of comparative trials by other observers, and their results in the
main Cheap Dostinex agree with the statements of Prof. Nagel. It is understood that a
large class of cases of amaurosis and amblyopia remain incurable, viz., such
as depend on extreme textural change; but for a considerable contingent,
which, by other methods are scarcely at all Buy Dostinex Online relieved, the hypodermic use of
strychnia has been greatly efficacious. Our present methods of diagnosis
do not show us the minute structure of the optic nerve and retina, and Generic Dostinex
we are therefore unable to tell, in a case of atropliy, just how far the fibres
or ultimate elements are impaired ; hence, the trial of Buy Dostinex any remedy must be
attended in all cases with a degree of uncertainty.
But what the method of Prof. Nagel has done is a positive gain. It is
as follows : He injects into the temple a moderate dose of nitrate of strych-
nia, say Order Dostinex from ^\ to ^^ grain every day for a week. He expects the effect
on vision to be produced within Cabergoline Buy an hour. This may be either in extension
of the limits of a contracted field, or in Buy Cabergoline the increase of direct vision. If
this result is not obtained within a few days, the dose is increased, but not
above yV of a grain. If no good elFect, the case is regarded as Dostinex Cost unsuited
for this treatment. The diseases for which this treatment has been greatly
useful have been, a boy with imperfect amaurosis of one eye, with concen-
tric limitation of the field, and no ophthalmoscopic appearances; after one
injection of ^'^j- grain nitrate strychnia, vision rose in half an hour from

—— to =:r and the field was a little enlarged. The improvement was

maintained Buy Cheap Dostinex for two days, when another injection of ^^ grain added a little
more Dostinex Price to the area of the field, and improvement afterward went on spon-
taneously to perfect cure.
Another case of amaurosis, following measles, complicated with head-
symptoms, was treated with perfect success. The interior of the eyes ex-
Idbited no lesions. Slow improvement of sight was taking place under
general tonics and hygiene ; but, to hasten the progress, strychnia Avas tried.
The first injection, of jV grain had no effect ; Purchase Dostinex a second, of jV grain, brought
vision from less than -- to .^. In a month after, four injections, v. = -—
Another case, a child of three years, in whom the state of the Dostinex Tablets optic
nerve was almost perfectly normal, although blindness was complete,
proved obdurate to strychnia. No treatment did any good.
Other classes of cases successfully handled were asthenopia of the
accommodative kind, amblyopia from disuse, traumatic amaurosis, etc.
A case of embolus of the central artery of the retina is contributed by
Prof Becker, in which the striking gradations of improvement in the field
are shown \>y diagrams. The case looks Purchase Dostinex Online more like one of neuritis, with
consecutive thrombosis, than pure embolus. At the beginning, t!ie arteries
were extremely small, and the nerve a little large, the region of the macula

appeared, but tlie nerve showed appearances of atrophy. Sucli are some ot
the important cases discussed in this pamphlet, and the treatment is well
worth imitating. Cabergoline 0.5 The use of strychnia by the stomacli, and sprinkled on u
blistered surface, does not have the same eftect as when injected. This
fact, moreover, has been substantiated in treating other diseases of the
nervous system, so that the recommendations of Prof. Nagel are well sup-
