title: Measured visual acuity of fellow eyes as a prognostic factor in macular hole surgery.
abstract: OBJECTIVE
  To investigate the effect of the vision of the fellow eye on the visual acuity of eyes after successful macular hole surgery.
  
  
  METHODS
  Prospective consecutive series.
  
  
  METHODS
  A consecutive series of eyes with successful macular hole closure were studied and assigned to one of two groups according to the visual acuity of the fellow eye; a group with visual acuity less than 20/200 and a group with visual acuity of 20/200 or better. Preoperative and postoperative visual acuity in the two groups was measured based on the logarithm of the minimal angle of resolution (LogMAR), and postoperative visual acuity was also determined by using the multiple-letter visual acuity chart, which permitted measurement of visual acuity at an extrafoveal point.
  
  
  RESULTS
  Group 1 (<20/200) consisted of 19 eyes and group 2 (>20/200) consisted of 51 eyes. LogMAR visual acuity at 6 months postoperatively was significantly better in group 1 than in group 2 (0.21 vs 0.41, P <.01). The logMAR change 6 months after surgery was significantly greater in group 1 than in group 2 (0.49 vs 0.23, P <.01). There was no significant difference between two groups in logMAR visual acuity at 6 months postoperatively determined with the multiple-letter visual acuity chart (0.20 vs 0.29, P >.05).
  
  
  CONCLUSIONS
  Visual recovery after successful macular hole surgery is inversely correlated with vision in the fellow eye. Learning to use eccentric fixation may contribute to visual improvement after macular hole surgery.
