Abstract

Purpose:

To study the relationship between retinal vessel diameter and qualitative and quantitative evaluations on spectral-domain optical coherence tomography in patients with diabetic macular edema.

Methods:

One hundred and eight consecutive eyes of 80 patients, with clinically significant macular edema underwent optical coherence tomography and color fundus photography. The authors evaluated the retinal thickness of the Early Treatment Diabetic Retinopathy Study grid and foveal pathomorphologies including cystoid macular edema and serous retinal detachment on the optical coherence tomography images. The diameters of the superotemporal or inferotemporal retinal vessels originating from the optic disk were measured using a computer-assisted technique.

Results:

The mean diameters of the superotemporal and inferotemporal venules were larger in eyes with diabetic macular edema than in healthy eyes. The mean diameter of the temporal venules but not the arterioles was associated with perifoveal thickening in the inferior subfield in eyes with diabetic macular edema (P = 0.014). Although the retinal thickening in the central subfield was not correlated with the diameters of the retinal vessels, eyes with foveal serous retinal detachment had larger mean diameters of superotemporal and inferotemporal venules than those without serous retinal detachment (P < 0.001).

Conclusion:

The mean diameters of the superotemporal and inferotemporal venules were significantly associated with foveal serous retinal detachment in diabetic macular edema.
