Static retinoscopy is performed when the patient has relaxed accommodative status. This can be obtained by the patient viewing a distance target or by the use of cycloplegic drugs (where, for example, a child's lack of reliable fixation of the target can lead to fluctuations in accommodation and thus the results obtained).
The network of blood vessels in the retina is not entirely genetically determined and thus even identical twins do not share a similar pattern. Although retinal patterns may be altered in cases of diabetes, glaucoma or retinal degenerative disorders, the retina typically remains unchanged from birth until death.
In some offices, this process is used to provide the starting point for the ophthalmologist or optometrist in subjective refraction tests. Here, lenses are switched in and out of a phoropter and the patient is asked "which looks better" while looking at a chart.
Retinoscopy is often used in children to measure their refractive errors. [13] This method is a type of objective refraction. It involves the provider shining a narrow beam of light into the eye to see the red reflex of the retina while adjusting differently powered lenses in front of the eye to look for a neutralized point of the reflex.

This may represent a single-vision lens prescription to improve near work, or the reading portion of a bifocal lens. OD is an abbreviation for oculus dexter, Latin for right eye from the patient's point of view. Oculus means eye. OS is an abbreviation for oculus sinister, Latin for left eye from the patient's point of view.

Ophthalmoscopy, also called funduscopy, is a test that allows a health professional to see inside the fundus of the eye and other structures using an ophthalmoscope (or funduscope).
