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 ...

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.

Indications The retinal examination is part of a complete physical examination. It is particularly important in patients with a history of such systemic diseases as diabetes, hypertension, and atherosclerosis. Patients with the human immunodeficiency virus (HIV) or the acquired immunodeficiency syndrome (AIDS) are also at increased risk for retinal ...

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.

METABOLISM OF THE RETINA [PDF]
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.

During the past 10 years ophthalmologists have altered the point of view of physicians toward minor disorders of gestation by demonstrating that rubella and Toxoplasma may produce severe structural defects in the fetus. Further studies on children who were affected by maternal rubella infections during the first trimester of pregnancy (in the ...

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 ...

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

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 ...

Hydroxychloroquine and the Retina
JAMA, 2015Hydroxychloroquine sulfate is widely prescribed in the treatment of systemic lupuserythematosus (SLE), rheumatoidarthritis, and related autoimmunediseases, and it has largely superseded the use of chloroquinephosphate for these conditions. Furthermore, hydroxychloroquine isnowbeingevaluated forothermedical uses, including controlofbloodglucose ...
