**Table 1:**
Baseline central macular thickness (CMT) and changes 3 months postoperatively classified into three categories according to optical coherence tomography findings (n = 24).

Base line/^{*}Change in CMT |
Improved |
Unchanged |
Worsened |

CMT ≤ 300 μm (n = 6) | 1 | 4 | 1 |

300 μm < CMT ≤ 400 μm (n = 10) | 5 | 2 | 3 |

400 μm < CMT ≤ 600 μm (n = 5) | 3 | 2 | 0 |

CMT > 600 μm (n = 3) | 1 | 1 | 1 |

^{*}A change in CMT was defined as a change of 20% or more. Improved = a 20% or greater decrease in CMT, unchanged = a CMT

change from 0%-20%, worsened = a CMT decrease of 20% or greater. CMT: Central Macular Thickness.
