Purpose:
To report spontaneous resolution of diabetic cystoid macular edema (CME) associated with spontaneous vitreofoveal separation.
Design:
Interventional case series.
Methods:
Optical coherence tomography (OCT) was performed on three eyes of three diabetic patients with CME before and after vitreofoveal separation.
Results:
In all three eyes, OCT showed cystic changes at the fovea with a slightly detached posterior hyaloid, which remained attached to the optic disk and the fovea. After spontaneous separation of the hyaloid at the fovea, there was resolution of the cystic cavities and restoration of the foveal depression.
Conclusions:
In some eyes of diabetic patients, CME is caused by a vitreous traction. Resolution of CME may occur after spontaneous vitreofoveal separation.
