Purpose: To describe the various morphologic patterns of diabetic macular edema demonstrated by optical coherence tomography (OCT). Methods: Retrospective chart review of 144 patients with clinically evident, diabetic macular edema. A total of 199 OCT scans (99 right eyes, 100 left eyes) were reviewed for the study. In addition to OCT evaluation, all patients underwent comprehensive ophthalmic history and examination. Results: All patients had diabetic retinopathy and diabetic macular edema. OCT demonstrated five distinct morphologic subgroups of diabetic macular edema: diffuse retinal thickening (192 [96%] of 199 scans), cystoid macular edema (114 [57%]), subretinal fluid without posterior hyaloidal traction (21 [11%]), posterior hyaloidal traction without traction retinal detachment (28 [14%]), and posterior hyaloidal traction with traction retinal detachment (4 [2%]). Including all morphologic subgroups, mean retinal thickness measured at the central fovea was 411 microns. Conclusions: Diabetic macular edema exhibits at least five different morphologic patterns. These include diffuse retinal thickening (96%), cystoid macular edema (57%), posterior hyaloidal traction without traction retinal detachment (14%), subretinal fluid without posterior hyaloidal traction (11%), and posterior hyaloidal traction with traction retinal detachment (2%).
