Mathis T, Mendes M, Dot C, et al. - This study was undertaken to determine if choroidal thickness (CT) increases at the time of exudative recurrence in diabetic patients with unilateral diabetic macular oedema (DME) treated with intravitreal injections of anti‐VEGF or dexamethasone. A real‐life, prospective, two‐centre study was performed over a 9‐month period examining diabetic individuals presenting with unilateral DME treated with anti‐VEGF or dexamethasone intravitreal injections, and CT was measured manually, utilizing the enhanced depth imaging module of the spectral domain optical coherence tomography. In total, 51 patients with unilateral DME were involved. The authors discovered that at the time of recurrence of DME treated with anti‐VEGF or dexamethasone injections, CT increased significantly in the affected eye. The CT may be an interesting new predictor for monitoring DME patients.
