retinoscopyn.

Brit.

/ˌrɛtᵻˈnɒskəpi/, U.S.

/ˌrɛtnˈɑskəpi/

Origin: Formed within English, by compounding. Etymons: retino- comb. form, -scopy comb. form.

Etymology: < retino- comb. form + -scopy comb. form. In sense 2 after French rétinoscopie (in rétinoscopie phosphénique , 1851 or earlier). In sense 3 probably after French rétinoscopique retinoscopic adj. (1880 in this sense; compare rétinoscopie , used later in 1880 in this sense). Compare retinoscope n., retinoscopic adj.

Ophthalmology.

†1. Visualization of the vascular pattern of the retina (of one's own eye). Cf. retinoscope n. 1. Obsolete. rare.

ΚΠ

1855 Maryland & Virginia Med. Jrnl. 4 413 Professor Burow..advances a step in retinoscopy.

†2. A technique for assessing the functional state of the retina by applying pressure to the eye to produce phosphenes. Obsolete. rare.

ΚΠ

1863 J. Hogg Man. Ophthalmoscopic Surg. (ed. 3) 135 There has recently been introduced from Paris a process for ascertaining the condition of the retina..which its proposer, M. Serres d'Uzès, calls ‘phosphenic retinoscopy’.

1868 Med. & Surg. Reporter 6 June 487/1 M. Serre d'Uzes introduced to the notice of surgeons a mode of subjective retinal exploration, which he designates as phosphenian retinoscopy.

3. A method for determining the refraction of the eye by projecting a beam of light into it and observing the movements of the illuminated area of the retina and the light reflected back through the pupil. Also: ophthalmoscopic examination of the retina (rare).An earlier name for this method was keratoscopy; it was also called skiascopy.

1880 London Med. Rec. 15 Apr. 158/1 ‘Retinoscopy’, or some such term, would be more correct than keratoscopy, seeing that really the cornea plays no part whatever in the appearances described.

1884 Encycl. Brit. XVII. 787/1 Retinoscopy..is useful in determining and correcting the refraction where the patients are..too stupid to assist with their answers.

1904 Science 17 June 920/1 Retinoscopy is..a necessary part of the modern oculist's equipment.

1961 Lancet 12 Aug. 356/2 Retinoscopy reveals a peculiar brown or grey streaking resembling vessels in distribution but not in colour; hence the term angioid streaking.

1996 Jrnl. Compar. Physiol. A. 179 185 Refractive state and corneal curvatures were measured in vivo by retinoscopy and ophthalmometry respectively.
