Cryosurgery of the Retina

International Ophthalmology Clinics, 1976
In 1931, J. Gonin presented his original concept that retinal detachment is caused by a retinal break and reattachment could be achieved by inducing inflammation around the break with diathermy and by simultaneous draining of subretinal fluid. The primary advantage of cryosurgery is the ability to penetrate the sclera and to create a retinal adhesion ...

Proteoglycans in retina

Progress in Retinal and Eye Research, 2002
In this article, we summarize the roles of proteoglycans in retinal tissue. Chondroitin sulfate and heparan sulfate proteoglycans are the major constituents in proteoglycans expressed in retinal tissue. Soluble heparan sulfate proteoglycans are found in the extracellular matrices of the basement membrane, such as the inner limiting membrane and Bruch's

Acetylcholine in the retina

Neurochemistry International, 1980
Acetylcholine in the retina is synthesized and released by a sparse group of amacrine cells that symmetrically line both margins of the inner plexiform layer. The action of these neurons is at once very selective (they affect ganglion cells of some functional classes, but not others) and rather diffuse (the dependence of the acetylcholine-sensitive ...

Drugs and the retina

Expert Opinion on Drug Safety, 2004
The retina is relatively protected from systemic drug administration because of the blood-retinal barrier, a highly selective mechanism adapted to providing a regulated homeostatic environment for this highly specialised tissue. However, a number of drugs have been associated with retinal toxicity.

The Retina and Hypertension

Postgraduate Medicine, 1969
Examination of the eye in hypertension can give information almost impossible to obtain by other means, such as how long the blood pressure has been elevated. Retinal arteriolar sclerosis reflects the wear and tear of the hypertensive process and should be graded separately from the ophthalmoscopic changes of hypertension. Grading systems are proposed.

Ubiquinone in the retina

Vision Research, 1968
Abstract Microspectrophotometric examination of retinal cells shows an absorbance maximum at 282 nm and a shoulder at 275 nm, the latter possibly due to ubiquinone. Extraction of bovine retinal cell outer segments and retinal cells free of outer segments, however, failed to reveal any ubiquinone; an upper limit of 0.6 n mole ubiquinone per eye being ...

METABOLISM OF THE RETINA

Archives of Ophthalmology, 1946
DURING the past few years the interest in retinal metabolism has been greatly intensified. Many investigations were made on the retina as part of a war emergency program. Because of this practical interest in a narrow but important subdivision of ophthalmology, this survey of the literature was made.

Zinc in the retina

Progress in Neurobiology, 2001
Experimental evidence exists to suggest that zinc can have positive and negative effects on the physiology of cells depending on the "local" concentration, localisation (extracellular vs. intracellular) and/or state (bound vs. free). The retina contains particularly high amounts of zinc suggesting a pivotal role in the tissue.

Nutrition and Retina

2005
The impact of nutrition on manifestation and progression of retinal diseases has become an important, controversial topic within recent years. The awareness of this topic in the general population has increased partially due strong commercial advertisements of supplements and diets.
