Purpose:

To classify the changes of macula with optical coherence tomography (OCT) and to analyze the visual prognosis according to the macular appearance in OCT after diabetic vitrectomy.

Methods:

We reviewed medical records of 60 eyes (56 patients) who had diabetic vitrectomy and had gradable OCT examination before and after surgery. We categorized OCT findings into several groups and analyzed visual prognosis after surgery according to macular appearance in OCT.

Results:

Preoperative macular appearance in OCT were normal fovea with or without macular traction (20 eyes), normal fovea with preretinal hemorrhage (17 eyes), tractional retinal detachment involving fovea (8 eyes), epiretinal retinal membrane (ERM) with cystoid macular edema (8 eyes) and vitreomacular traction (7 eyes). The most common macular appearance after surgery was normal fovea (28.3%). ERM and diffuse macular thickening were found in 21.7% and 15%, respectively. Good visual outcomes (best corrected visual acuity > 20/50) after surgery were found in normal fovea, ERM and edema outside fovea. Moderate visual outcomes (20/80 < best corrected visual acuity ≤ 20/50) were found in subfoveal hard exudate, diffuse macular thickening and cystic macular change. Poor visual outcomes (best corrected visual acuity ≤ 20/125) were found in subfoveal fibrosis, macular hole, loss of foveal depression and subfoveal serous detachment.

Conclusions:

Good visual outcomes after diabetic vitrectomy were found when macular appearance in OCT showed normal fovea, ERM and edema outside fovea. Visual prognosis after diabetic vitrectomy correlated with OCT findings of macula after surgery.
