title: Tomographic features of early macular hole closure after vitreous surgery.
abstract: OBJECTIVE
  To report the optical coherence tomographic features of macular hole closure in the first months after vitreous surgery.
  
  
  METHODS
  We studied prospectively the tomographic features of 28 eyes (28 patients) with idiopathic macular holes before and after vitreous surgery by optical coherence tomography. We compared the best-corrected visual acuity levels with the postoperative tomographic features.
  
  
  RESULTS
  The 25 eyes with successfully sealed macular holes had one of two tomographic features within 1 month postoperatively: simple closure (normal foveal configuration) in 14 eyes (56%) or a bridge formation at the fovea that mimicked a foveal retinal detachment in 11 eyes (44%). It took an average of 2.0 months (range, 0.8 to 3.5 months) for the bridge tissue to attach to the retinal pigment epithelium. Best-corrected visual acuity quickly improved in the former group; visual improvement began 1 month after attachment of the bridge tissue in the latter group. A closed hole reopened 4 months postoperatively in one eye with a bridge formation.
  
  
  CONCLUSIONS
  Idiopathic macular holes have one of two patterns early after surgical closure, simple closure or a bridge formation. Visual improvement starts after the fovea assumes a normal configuration. The bridge formation appears to reflect an early phase and fragile condition in the anatomic closure of macular holes.
