Choroidal

Temperature modulating action of choroidal blood flow. ❋ Unknown (2006)

The stabilizing effect of the choroidal circulation on the temperature environment of the macula. ❋ Unknown (2006)

After abandoning his ligature of the anterior choroidal artery on account of the variability of the area supplied by this artery, Cooper inserted a cannula directed by a simplified guiding device in order to inject fluids into the pallidum; in other words, he employed a stereotactic technique. ❋ Spiegel, Ernest A. (1982)

She suffered, we afterwards concluded, from choroidal tuberculosis. ❋ Various (N/A)

There was extensive damage to both eyes, hæmorrhage, and probably retinal detachment as well as choroidal changes. ❋ George Henry Makins (N/A)

In cases in which permanent blindness was produced without solution of continuity of the sclerotic coat, the nature of the lesion was probably in most cases vibratory concussion and the development of multiple hæmorrhages from choroidal ruptures of a similar nature to those seen in the brain and spinal cord. ❋ George Henry Makins (N/A)

The spongy nature of this meshwork affords free access of aqueous to the venous sinus of Schlemm, thence by tributaries into the supra-choroidal space and anterior uveal venous system. ❋ Various (N/A)

Whether the action of the eserin on the choroidal circulation, which is maintained by Wahlfours, aids in this favorable action of the myotics remains to be proved. ❋ Various (N/A)

A patient, then aged 21, suffered three years ago from a scotoma almost central; and was first seen six months after that with a macular choroidal atrophy and abnormal pigmentation. ❋ Various (N/A)

The pioneer in this seems to have been Purkinje, who described cells in the choroidal plexus in ❋ Unknown (N/A)

Furthermore, the possibilities of damage by hemorrhage from the choroidal or retinal vessels, delayed formation of the anterior chamber and adhesion of the capsule of the lens to the wound, and the injurious effects of even slight trauma subsequent to the operation, including loss of vitreous, are increased by omitting the conjunctival flap. ❋ Various (N/A)

Passing backward and lateralward between the temporal lobe and the cerebral peduncle, it enters the inferior horn of the lateral ventricle through the choroidal fissure and ends in the choroid plexus. ❋ Unknown (1918)

The anterior choroidal (a. chorioidea; choroid artery) is a small but constant branch, which arises from the internal carotid, near the posterior communicating artery. ❋ Unknown (1918)

Sometimes the choroidal fissure persists, and when this occurs the choroid and iris in the region of the fissure remain undeveloped, giving rise to the condition known as coloboma of the choroid or iris. ❋ Unknown (1918)

The mesoderm which enters the cup through the choroidal fissure and around the equator of the lens becomes intimately united with this reticular tissue, and contributes to form the vitreous body, which is therefore derived partly from the ectoderm and partly from the mesoderm. ❋ Unknown (1918)

The invagination is not limited to the outer wall of the bulb, but involves also its postero-inferior surface and extends in the form of a groove for some distance along the optic stalk, so that, for a time, a gap or fissure, the choroidal fissure, exists in the lower part of the cup (Fig. 865). ❋ Unknown (1918)

The fissures comprise the choroidal and hippocampal already described, and two others, viz., the calcarine and collateral, which produce the swellings known respectively as the calcar avis and the collateral eminence in the ventricular cavity. ❋ Unknown (1918)

Parallel with but above and in front of the choroidal fissure the medial wall of the cerebral vesicle becomes folded outward and gives rise to the hippocampal fissure on the medial surface and to a corresponding elevation, the hippocampus, within the ventricular cavity. ❋ Unknown (1918)

This invagination constitutes the choroidal fissure, and extends from the interventricular foramen to the posterior end of the vesicle. ❋ Unknown (1918)

By the downward and forward growth of the posterior end of the vesicle to form the temporal lobe the choroidal fissure finally reaches from the interventricular foramen to the extremity of the inferior horn of the ventricle. ❋ Unknown (1918)
