Subfoveal choroidal thickness in eyes with diabetic macular oedema using swept source optical coherence tomography.

Purpose: To compare subfoveal choroidal thickness (GCSF) in patients with diabetic macular oedema (DMO) and healthy subjects using swept source optical coherence tomography (SS-OCT).

Method: Cross-sectional study including 50 eyes of 36 patients with DMO, and 47 eyes of 34 patients as a control group. GCSF was measured in both groups, analysing between the eyes with DMO according to the type of oedema (predominantly cystic or diffuse).
