WebChildren were excluded due to the inability to perform accurate visual acuity testing. The Snellen visual acuity was converted to its logarithm of minimal angle of resolution (logMAR) equivalent as previously described; count-fingers was assigned a logMAR value of 1.9, hand motion 2.3, light perception 2.7, and no light perception 3.0. 7 WebAug 22, 2016 · In this paper, the authors describe an online tool with which to convert and thus quantify count finger measurements of visual acuity into Snellen equivalents. It is hoped that this tool allows...

HM - Hand Motion (ophthalmological test of visual acuity)
WebVisual acuity calculations were made using the logMAR scale with the following values assigned to the lowest visual acuities: anophthalmic or NLP (no light perception) − 3, LP (light perception) − 2.8, HM (hand motion) − 2.3, CF (count fingers) − 1.85. 17–19. The ZOI was defined based on the anatomic location of the rupture or laceration. WebMedian presenting visual acuity was Hand Motion in both groups. Median visual acuity at last followup measured 20/40 in the IVD group and 20/50 in the No-IVD group (p = 0.75). Seventy-three percent of patients in the IVD group and 82% of patients in the No-IVD group achieved a ≥3-line improvement in visual acuity (p = 0.42). WebMar 1, 2004 · The logMAR-visual acuity (LVA) levels were considered as 2.0 at cases only counting ngers, 2.3 at children detecting hand motion, 2.7 at cases with only light perception and 3.0 at children with ... hypnosis clinic
