Anterior chamber angle shape of patients with diabetic retinopathy at different stages

Abstract

AIM: To observe the anterior chamber angle shape of patients with diabetic retinopathy(DR)at different stages using OCT, and to explore a more sensitive and accurate glaucoma preventing measure. METHODS: A total of 613 cases of DR patients were divided into proliferation phase group(353 cases)and background phase group(260 cases), another 100 cases of patients with only diabetes were selected as control group. OCT was used to detect the anterior chamber angle related parameters, including angle opening distance(AOD), trabecular-iris space area(TISA), angle recess area(ARA), anterior chamber depth(ACD)and anterior chamber angle(ACA).RESULTS: There were significant difference among AOD500, AOD750, TISA500, TISA750, ARA500 and ARA750 of control group, proliferation phase group and background phase group(P2, 0.45±0.19mm2, 0.29±0.18mm and 0.46±0.15mm, respectively. There were significant difference among ACA500, ACA750, ACD500 and ACD750 of control group, proliferation phase group and background phase group(PCONCLUSION: Anterior chamber angle shape detected using OCT can reflect the change of retinopathy. OCT is an accurate and simple technique for detecting DR staging.
