On aqueous humour, micro-organisms, and immunity

Erythromycin in the aqueous humour.

Aqueous humour vitamin B12 and intramuscular cobalamins.

Previous work on the vitamin B12 content of the aqueous humour (Phillips, Ainley, van Peborgh, Watson-Williams, and Bottomley, I968) suggests that the levels found in a series of mainly elderly patients (mean: 299 pg./ml.) are of the same order as those found in cerebrospinal fluid (mean: 21 pg./ml.) (Kidd, Gould, and Thomas, I963). As an extension of this study, the response of aqueous vitamin...

Acute choroido-retinitis in secondary syphilis. Presence of spiral organisms in the aqueous humour.

The importance of syphilis as a cause of eye disease has been appreciated since the discovery of the relationship between interstitial keratitis, uveitis, and congenital syphilis by Jonathan Hutchinson in the middle of the 19th century (Hutchinson, 1858). Many years ago Moore (1931) made a plea for a greater awareness of syphilis as a cause of uveitis and reported that 4-6 per cent. of patients...

The Theories on the Formation of the Aqueous Humour.

FOR many years there has been controversy, becoming very bitter at times, regarding the mechanism of formation of the aqueous humour. This fluid has at various times been considered a dialysate, a transudate, an exudate or a secretion, and very strong arguments have been brought forward for and against the various concepts by particular experimentalists partial to one or the other theory. Befor...

'What controls aqueous humour outflow resistance?'.

The bulk of aqueous humour outflow resistance is generated in or near the inner wall endothelium of Schlemm's canal in normal eyes, and probably also in glaucomatous eyes. Fluid flow through this region is controlled by the location of the giant vacuoles and pores found in cells of the endothelium of Schlemm's canal, but the flow resistance itself is more likely generated either in the extracel...
