Cycloplegia in African-American Children

Optometry and Vision Science, 1999
The selection of a cycloplegic agent depends on the desired outcome, the characteristics of the patient receiving the drug, and the associated risks. The Orinda Longitudinal Study of Myopia (OLSM) has used 1% tropicamide to assess the ocular components and cycloplegic refractions in a large cohort of predominantly Caucasian children.

Traumatic Cycloplegia and Myopic Anisometropia

Journal of Ocular Pharmacology and Therapeutics, 1996
The pathogenesis of myopia and the mechanism of atropine in preventing myopic progression have long been widely discussed. Recent studies with animals have pointed to the possible role of the muscarinic receptor of the retina itself in regulating eye growth.

This is no doubt due in large measure to the increasing use of diphtheria prophylaxis. During the course of World War II there was a flurry of reported cases of diphtheria in the armed forces, with varying ...

Archives of Ophthalmology, 1934
The physiologic action of Hyoscyamus was known to the Greeks. Belladonna, used in a cosmetic during the sixteenth century, probably got its name from the fact that it produced dilatation of the pupil. That stramonium leaves poisoned the early settlers of Virginia, who ate them as greens, gave the plant the popular name of Jamestown (or jimson) weed ...

"HOMATROPINE AND ATROPINE CYCLOPLEGIA"

Archives of Ophthalmology, 1932
To the Editor .—May I express my thanks to Dr. Linn Emerson (Arch. Ophth. 7 :954 [June] 1932) for calling my attention to his article in the Medical Digest of October, 1904, and for the copy of the tabulated results? I am indeed sorry that I did not find any reference to it, though I went back as far as 1880 in my search through the literature.

Evaluation of Drugs in Ointment for Mydriasis and Cycloplegia

Archives of Ophthalmology, 1978
Ointment preparations of cyclopentolate hydrochloride and tropicamide were compared with aqueous drops of these medications for the production of mydriasis and/or cycloplegia in clinic patients. Mydriasis and/or cycloplegia could be accomplished by the single application of a minute volume (around 0.005 ml) of ointment containing these drugs.
