Retinoscopy - EyeWiki
网页Retinoscopy is an exam technique that objectively measures the refractive error of the eye. This is done by looking through an optical instrument called a retinoscope to observe the movement of reflected light in a patient’s pupil.
Retinoscopy - Wikipedia
网页Retinoscopy is a technique to obtain an objective measurement of the refractive error of a patient's eyes. [1] The examiner uses a retinoscope to shine light into the patient's eye and observes the reflection (reflex) off the patient's retina.
Retinoscopy 101 - American Academy of Ophthalmology
网页2015年5月16日 · Reflex motions in retinoscopy. Starting with the right eye, shine the retinoscopy streak into the patient’s eye and move it from side to side. Determine if the light reflex in the patient’s pupil moves “with” or “against” motion (Figure 2). Rotate the axis of the streak and look at the reflex in different meridians.
Retinoscopy Simulator - American Academy of Ophthalmology
网页2020年4月22日 · The interactive Retinoscopy Simulator is designed for students to learn and practice the principles of retinoscopy. Visualize how light reflexes in an eye with various refractive errors and amounts of astigmatism, and from various working distances. The simulator allows adjustment of spherical power, cylinder power, and cylinder axis.

网页2023年10月28日 · Retinoscopy is an exam technique that utilizes an external light source supplied by a retinoscope to project light rays through the transparent ocular media to observe their reflection off the retina.
Retinoscopy from A to Z—with Downloadable Cheat Sheet - Eyes …
网页2022年4月28日 · Retinoscopy (or skiascopy) is a technique that uses light and lenses to determine “where” the far point lands and quantifying that measure. Based on the eye’s light reflex we can get a baseline reading and understanding of the patient’s refractive error. Relevant qualitative input can be seen with the retinoscope as well.
Retinoscopy - American Academy of Ophthalmology
网页2024年10月4日 · A, In retinoscopy, the examiner’s eye is conjugate with the patient’s pupil. B, At the point of neutrality, the patient’s retina is conjugate with the retinoscope peephole. C, With the working distance subtracted, the patient’s retina is conjugate with optical infinity.
Retinoscopy - American Association for Pediatric Ophthalmology …
网页Retinoscopy (also called skiascopy) is a technique to figure out the refractive error of the eye (farsighted, nearsighted, astigmatism) and the need for glasses without having to ask “which is better, one or two.” The test can be quick, easy, reliably accurate and needs little cooperation from the patient. How is it performed?
