Abstract
PURPOSE:
To study the visualization of the vitreoretinal interface in diabetic macular edema patients using three-dimensional optical coherence tomography (3 D-OCT) and to compare it to surgical findings.
METHODS:
We prospectively examined the medical records of 25 patients (30 eyes) with diabetic macular edema measured by 3 D-OCT (optic disc and macular lesions) who received vitrectomy between August 2006 and February 2007. We compared the findings of 3 D-OCT to the findings during surgery using triamcinolone acetonide.
RESULTS:
Posterior vitreous membrane was found in 18 eyes using 3 D-OCT. The findings in all cases corresponded to operative findings. Six cases were characterized by posterior vitreous membrane attached to the optic disc and macular area. Twelve cases were characterized by posterior vitreous membrane diffusely attached to the posterior pole.
CONCLUSIONS:
Vitreoretinal interfaces were visualized using 3D-OCT and confirmed by operative findings. 3 D-OCT is an effective tool to determine the pathogenesis of diabetic macular edema.
