    ABSTRACT: There are many theories surrounding the etiology of ingrown toenails (IGTN). Few factors have been formally assessed, but it is widely accepted that a poor nail cutting technique has a causative role. To investigate the hypothesis that decreased visual acuity may lead to inadequate nail cutting and the formation of IGTN. A prospective case-control study was performed. Near and distance visual acuity were tested on a population with IGTN (n = 19) and compared with that of an age- and sex-matched control cohort (n = 24) who underwent epidermal cyst excision in the same tertiary referral center. Comparisons of visual acuity were made between groups by Mann-Whitney U-test. Differences were taken to be significant if P < 0.05. Institutional Review Board approval was sought and granted. No significant difference in visual acuity (near or distance) was demonstrated between patients with IGTN and the control group (P = 0.33). Visual acuity does not appear to play a significant role in the development of IGTN.
