title: Fixation stability and location in patients with unilateral idiopathic epiretinal membrane.
abstract: OBJECTIVE
  To explore fixation stability of patients with decreased vision due to idiopathic epiretinal membrane.
  
  
  METHODS
  Fourteen consecutive patients with unilateral idiopathic epiretinal membrane participated. Visual acuity was measured with ETDRS, and fixation stability was recorded with the MP-1 microperimeter (Nidek Technologies Srl., Vigonza, Italy) for both eyes. Informed consent was obtained from all participants.
  
  
  RESULTS
  Visual acuity of the affected eye (mean = .45 ± .23 LogMAR) was significantly worse than that of the contralateral eye (mean = .11 ± .16 Log-MAR), P < .0001. Fixation stability of the affected eye was not significantly different from that of the contralateral eye. There was a high correlation between fixation stability of the affected and contralateral eyes, r(12) = .67, P = .0087. Moreover, fixation was central or within 3 degrees from the fovea.
  
  
  CONCLUSIONS
  Despite lower visual acuity, untreated eyes with idiopathic epiretinal membrane have unimpaired central fixation.
