Vitreomacular traction syndrome confused with pseudophakic cystoid macular edema.

Vitreomacular traction syndrome causes visual loss as a consequence of persistent traction on the fovea from an attached posterior hyaloid. The diagnosis can be challenging because the attachment may be subtle. Cystoid macular edema secondary to cataract extraction is well known and can occur in the absence of any surgical complication. Herein, a patient is described who had vitreomacular traction syndrome diagnosed after uneventful cataract surgery. Pars plana vitrectomy with detachment of the posterior hyaloid restored vision to an acceptable level. Careful examination and clinical suspicion are important because recognition and surgical intervention will benefit the majority of these patients.
