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 ...

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.

Current Hypertension Reports, 2023
This review summarizes key findings relating to the association between preeclampsia and retinal disorders.Preeclampsia is a major cause of maternal morbidity. Pregnant women with preeclampsia frequently describe having visual disturbances. Retinal changes can be identified on fundoscopy in most patients with preeclampsia.

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.

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 ...

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.

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.

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.

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 ...
