The dynamic retinoscopy technique that has undergone the most quantitative study is the Monocular estimate method (MEM). For reasons of examiner preference, patient cooperation, or equipment availability it may be useful for the practitioner to have alternative methods available to assess accommodative status. The purpose of this study was to compare data obtained by two experienced examiners using Bell, Cross, and Nott retinoscopies, MEM and Binocular cross cylinder (BCC) to evaluate accommodative lags of 10 young adult subjects. Statistical analysis revealed no significant differences between the results of the two examiners (p less than 0.2672). Results obtained by the MEM, Cross, and Nott techniques were not significantly different, but those obtained by Bell and BCC were significantly different from the other three techniques. The results of this study suggest that an examiner may use MEM, Cross retinoscopy, or Nott retinoscopy interchangeably to evaluate accommodative lag of the young adult subject.

UI MeSH Term Description Entries
D008297 Male Males
D012160 Retina The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent. Ora Serrata
D005260 Female Females
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000065 Accommodation, Ocular The dioptric adjustment of the EYE (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. Ocular accommodation is the effecting of refractive changes by changes in the shape of the CRYSTALLINE LENS. Loosely, it refers to ocular adjustments for VISION, OCULAR at various distances.

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D014787 Vision Tests A series of tests used to assess various functions of the eyes. Test, Vision,Tests, Vision,Vision Test
D014792 Visual Acuity Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast. Acuities, Visual,Acuity, Visual,Visual Acuities
