The OCT images described herein provide additional information for understanding
the repair process of idiopathic macular holes. We found 2 anatomical changes
occurring in the fovea. First, the roof of the cyst gradually increased in
thickness and its separation from the underlying layer diminished (vertical
change). The second was reapproximation of the edge of the disrupted outer
retinal layers (horizontal change). We measured the thickness of the roof
and vertical and horizontal diameter of the cyst in case 1 to see how the
fovea changes. The thickness of the roof before the surgery and at postoperative
days 1 and 4 measured 60 µm, 88 µm, and 108 µm, respectively.
The horizontal diameter of the cyst measured 250 µm, 240 µm, and
180 µm, respectively. These facts indicate that disrupted outer retinal
layers begin to reapproach as well as the gradual depression of the roof of
the cyst, increasing its thickness following the release of vitreous traction.
