Serotonin in Human Aqueous Humor
Ophthalmology, 1988Circadian rhythms in serotonin metabolism have been observed in the pineal gland and retina, and there is evidence that the levels of serotonin and melatonin in these tissues may mediate events in the brain's sleep-wake cycle and the retina's cycle of disc shedding.

In a series of papers, Kinsey * developed the technique of posterior chamber taps and has applied this technique both to the study of steady-state relations between plasma and posterior and anterior chamber concentrations of normal constituents3and to the analysis of aqueous humor dynamics as disclosed by the changing concentrations of a test substance

IS THE AQUEOUS HUMOR A DIALYSATE?
Archives of Ophthalmology, 1933Within the last few years there have been a rapid development and change in the ideas of ophthalmologists concerning the formation of aqueous humor. The evidence obtained from laboratory experiment and clinical observation has been gathered together and woven into three distinct theories.

Aqueous Humor Levels of Cytokines in Patients with Age-Related Macular Degeneration
Ophthalmologica, 2018Purpose: To compare aqueous humor levels of various cytokines between patients with age-related macular degeneration (AMD) and cataract patients. Methods: Thirteen eyes with wet-type AMD (AMD group) and 14 eyes with cataract (cataract group) were studied.

Human aqueous humor catecholamines
Current Eye Research, 1985Timolol of 0.5% was applied in 6 eyes prior to cataract extraction, while 7 eyes were not treated. Aqueous humor was drawn after retrobulbar analgesia with 2% lidocaine and analyzed for epinephrine and norepinephrine using a radioenzymatic assay. Epinephrine levels averaged 15.8 +/- 16.2 and 19.3 +/- 27.5 pg/ml in the timolol treated group and controls

Aqueous humor angiography, or aqueous angiography, is an anterior segment imaging technique capable of visualizing the conventional/trabecular aqueous humor outflow pathways. As a translational technique, it is applicable for in vivo imaging in living subjects and ex vivo imaging using whole-globe preparations or anterior segment perfusion setups ...

Aqueous-Humor Concentrations of Amikacin
Archives of Ophthalmology, 1983To the Editor. —Wingfield et al, in the JanuaryArchives(1983;101:117-120), reported on aqueous humor concentrations of amikacin following 7.5-mg/kg doses injected intramuscularly in man. While we found their data to be of interest, we disagree with several of their statements.

Archives of Ophthalmology, 1929
The science of Galen prevailed until Andreas Vesaleus revealed by his dissection of the ocular tissue of man that the anterior humor of the eye did not resemble the white of an egg but was of a watery nature. Jacob Hovius (1702) some years later described the influx and efflux of this watery fluid in the anterior part of the eye.

Journal of the American Medical Association, 1926
In the last sixty years, considerable has been written on the mechanism of production of the intra-ocular fluids. The experimental evidence discloses many discrepancies which must be cleared away before the whole situation can be understood. Those who have studied the subject are still far from an agreement as to the mode of formation of the intra ...

Agar Microelectrophoresis of the Aqueous Humor
Archives of Ophthalmology, 1958Electrophoretic determination of protein values in normal aqueous humor offers considerable difficulties, owing to the following two factors: Proteins are present only in minute quantities, whereas there are considerable quantities of salts as against the low protein concentration.
