All cycloplegics are also mydriatic (pupil dilating) agents and are used as such during eye examination to better visualize the retina. When cycloplegic drugs are used as a mydriatic to dilate the pupil, the pupil in the normal eye regains its function when the drugs are metabolized or carried away.
Therefore, to achieve the most accurate measure of refractive errors, cycloplegic refraction, which paralyzes the ciliary muscle and prevents accommodation, is often performed. [20] This involves using cycloplegic eye drops, such as cyclopentolate and tropicamide. [13] [20] Often, the effect of the medications could last for several hours to a ...
Pseudomyopia may be either organic, through stimulation of the parasympathetic nervous system, or functional in origin, through eye strain or fatigue of ocular systems. It is common in young adults who have active accommodation , and classically occurs after a change in visual requirements, such as students preparing for an exam, or a change in ...
Spasm of accommodation is frequently resistant to treatment. However, some patients do find relief through the use of daily eye dilation with cycloplegic drops. One side effect of cycloplegic drops is that they often have BAK as a preservative ingredient, which, with daily use, can erode the tear shield:
Astigmatism: Astigmatic eye may also be associated with accommodative excess. ... Optical: Cycloplegic refraction, and correction of Refractive errors if any [3]
Drugs such as tropicamide are used in medicine to permit examination of the retina and other deep structures of the eye. Mydriatics typically also have a cycloplegic effect, reducing or paralyzing the accommodation reflex which may also be used for certain ophthalmic examinations or treatments, such as reducing painful ciliary muscle spasm.
n November 1954, 29-year-old Sammy Davis Jr. was driving to Hollywood when a car crash left his eye mangled beyond repair. Doubting his potential as a one-eyed entertainer, the burgeoning performer sought a solution at the same venerable institution where other misfortunate starlets had gone to fill their vacant sockets: Mager & Gougelman, a family-owned business in New York City that has ...
Refractive changes at high altitude: Changes in refractive power of post RK corneas at high altitude has been well documented. There is a significant increase in the cycloplegic refraction as well as corneal thickness measurements in RK corneas exposed to high altitude. [ 17 ]
