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 monocular estimate method or monocular estimation method is a form of dynamic retinoscopy widely used to objectively measure accommodative response. [1] [2] Values normally attained when performing MEM are between +0.25 and +0.50 diopters. [2]
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).

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. [13]
The idea for retinal identification was first conceived by Carleton Simon and Isadore Goldstein and was published in the New York State Journal of Medicine in 1935. [5] The idea was ahead of its time, but once technology caught up, the concept for a retinal scanning device emerged in 1975.
Retinotopic maps with explanation. Retinotopy (from Greek τόπος (tópos) 'place') is the mapping of visual input from the retina to neurons, particularly those neurons within the visual stream.
