is best seen with the inverted image, bnt it is seen too with Order Oxybutynin the upright
imaji:e in Purchase Ditropan Online some cases, as Dr. Loring asserts, conti-ary to Mauthner's state-
ment, and in this we agree with him.
On the appearance of the reflex from the fovea, Dr. Loring says:
"Even when present, it is not, however, always of a crescentic shape, for it
sometimes has tlie appearance as if it were only tlie segment of a small
circle which Avas ilhiniinated, or as if the fossa Vr^ere a triangular one, and
light were reflected from only one side of it, in which case the reflection
streams out something like the tail of a very inioute comet; again, it has
the appearance of a delicate phantom-like veil, stretched in part or entirely
across the fovea; and then, again, there is no reflex at all, and the fovea
looks like Purchase Oxybutynin a small, yellow dot, varying in size and shape, and has the ap-
pearance as if it had been flecked directly on to the surface of the retina
with a brush.
" May not these differences in effect of the reflection, when present, be
due to variations in anatomical construction of the part, and principally to
differences in shape and depth of the excavation ; Buy Cheap Oxybutynin and, when the reflex is
absent, may not its absence be due to the want of any difference in level?"
28. — Cases of Choroidal MeJano-sarcoma^ with Phthisis Bulbi. By Dr.
Bekthold, [Arehiv fur Ophthal., Jahr. xvii., Abth. 1, S. 185.]
The cases were chiefly remarkable for the age of the subjects, one thir-
teen, tlie other twenty. In both the eyeballs had become atroi)hied in
early childhood, in one even congenitally. It was assumed that the cause
was panophthalmitis from the growtli of the tumor. These cases, with
some published by Knapp, and others by Forster, are presented as an off"-
set to tlie prevailing belief in the great malignancy of choroidal sarcomata.
They are extremely prone to recurrence; and Graefe, in 1864, could recall
no instance in which there had been exemption for more than four years.
To have even a few cases with a less gloomy prognosis is satisfactory. Generic Ditropan On
the other hand, it is shown that the disease may make its inroad at a much
earlier period than is usually assigned to it.
(A case of choroidal sarcoma in my private collection was taken from a Purchase Ditropan
boy twelve years old. I have had no information about its recurrence. —

29. — Tlie Origin of the so-called Glassy Excrescences on the Choroid of
the Human Eye^ and the Nature of Hyaline Degeneration of its Ves-
sels. By Dr. Alex. Eudxew. [Virchow's Arehiv., Band liii,, Heft 4,
pp. 455-4G5.]
The little masses in question were examined by Donders and Mliller
many years ago, and called by the former "colloid globules." Others have
since written upon them. They appear beneath the epithelium on the
glassy lamella of the choroid, and Buy Oxybutynin Online vary from -^-^ to -J- millimetre in diameter.
They are extremely indifferent to chemical reagents.
Dr. Rudnew regards these masses as due to transformation of emigrated
white blood-corpuscles; he finds them at all ages, and tiiinks their more
frequent occurrence in the old is because in Order Oxybutynin Online them vascular obstructions are
the most common. In this opinion Dr. Rudnew differs from Donders, who
thought they came from the nuclei'of the epithelium.
In a case of purulent choroiditis accompanying purulent meningitis. Dr.
Rudnew found extensive hyaline metamorphosis of the walls of the vessels.
Some vessels were thus completely occluded. There was also great abun-
dance Purchase Oxybutynin Online of the above-mentioned hyaline globules. It was possible to see that
the transparent substance in the Cheap Ditropan vessels was made by fusion of small
masses, and Dr. Rudnew concludes that the glassy state of the vessels
originates like the glassy bodies of the hyaline lamella, from changes Oxybutynin Online of the
white blood-corpuscles.
OPHTHALMOLOGY, 321
80. — Formation of Bone in the Eye. By Dr. II. Knapp. [ArcLives for
Oph. and OtoL, vol. ii., No. 1, p. L]
A careful description is given of tlie minute appearances in five globes
iQ which ossific deposit had taken place. It is clearly shown Buy Oxybutynin that there
was actual bony production as distinguished from calcification. Dr. Knapp
attempts to show in what particular structure, and under Avhat Ditropan Online conditions,
osteoid growth occurs. His conclusions arc, that true ossification has only
been found in exudations from the choroid. Calcareous deposits, on the
other hand, have been observed in all the structures of the globe. At its
beginning tiie bony formation appears in the chorio-capillaris in small
plates, which are covered by the hyaline membrane and epithelium.
Where there is more abundant exudation of plastic lymph, the bone-tissoe
becomes correspondingly thicker, and it iriay in some cases extend in a
transverse septum across the anterior part of the vitreous, behind the
ciliary body and lens, without involving those parts.
The diseases leading to Order Ditropan this gi'owth are chronic inflammations of the
iris and choroid. Both ossification and calcification may occur at once.
The diagnosis of either is made by feeling a hard and resisting Buy Ditropan Online mass in the
deeper part of the Buy Cheap Ditropan globe, beginning about two Buy Ditropan lines behind the cornea,
while the anterior parts are soft, or at least impressible.
The paper concludes with these remarks: "As ossification does not
involve the outer choroidal layers, nor the Order Ditropan Online ciliary muscle and iris, it in
itself is not to be dreaded as a cause of sympathetic ophtlialmia. The
latter can only result from irido-cyelitis supervening as a complication to
ossific choroiditis.
"As long as an eye in whicli ossification is diagnosticated remains free
from irritation, and its fellow also, the removal of the former for fear of
sympathetic inflammation is not indicated. To corroborate this, I may-
state that I have not unfrequently observed cases in which eyes bearing
the signs of ossification, and even being tender to the touch, in the ciliary
region, were tolerated witiiout annoyance for twenty, thirty, and fortv
years."
