“…RAM technology has been shown to measure retinal acuity at statistically significant levels in eyes with maculopathy, glaucoma, opaque posterior capsule, and cataract associated with vision loss to the 20/200 level. 16,[18][19][20][21] The difference between standard lighting acuity and retinal acuity is vision loss attributable to ocular conditions [16][17][18][19][20][21] such as uncorrected refractive error, corneal conditions, cataract, and other opacities in the ocular media and is termed the ''ocular component of visual reserve.'' For measurement of standard lighting acuity and retinal acuity, each eye was tested separately.…”
