Abstract

Purpose: : To describe various morphologic patterns of diabetic macular edema demonstrated by optical coherence tomography (OCT) and propose a new classification of this clinical entity based on OCT findings.

Methods: : We carried out a prospective study including 314 eyes of 174 patients with diabetic retinopathy at different stages. In addition to the routine ophthalmic examination, patients were examined with OCT. minimum of six radial B-scans and a macular mapping were performed for all patients. The patterns on OCT were correlated with visual acuity.

Results: : Of 314 eyes, 297 (94.6%) had increased macular thickening on OCT. Five morphologic patterns of diabetic macular edema were observed.Type 1. Focal macular thickening (29.6%)Type 2. Diffuse noncystoid macular thickening (19.5%)Type 3. Diffuse cystoid macular thickening (31.3%)Type 4. Tractional macular edema due to:4a. Posterior hyaloid traction (5.7%)4b. Epiretinal membrane (4.7%)Type 5. Serous retinal detachement (9.1%)Increasing retinal thickness in all patterns was significantly correlated with worse visual acuity. Types 3 to 5 were also significantly associated with worse vision.

Conclusions: : Diabetic macular edema exhibits at least five different morphologic patterns on OCT. There is a significant correlation between retinal thickness and visual acuity. This new classification is useful to better diagnose, catalogue, and follow diabetic macular edema.
