Ocular hemodynamics study on acute angle-closure glaucoma with color Doppler flow imaging
Mai D; Wei ZChinese Ophthalmic Research 2002; 20: 457-458
OBJECTIVE: To observe ocular hemodynamic changes in cases with acute and subclinical stages of acute angleclosure glaucoma (AACG). METHODS: Thirty-three eyes with the acute stage and 19 with the clinical previous stage of acute angle-closure glaucoma, and 66 normal eyes used for control, were tested with color Doppler flow imaging. RESULTS: The end diastolic velocity (EDV) of the central retinal artery (CRA), posterior ciliary artery (PCA), and ocular artery (OA) was decreased (p < 0.01). The resistance indexes (RI) of PCA and OA were significantly higher in the acute stage group (p < 0.01). The EDVs of PCA, OA were decreased, and RI remarkably higher, in the clinical previous stage group (p < 0.01). CONCLUSIONS: AACG in the acute stage may result in the deterioration of visual function, due to ocular circulatory disturbance. There is a circulatory disturbance of PCA and OA in the clinical previous stage of AACG. LA: Chinese
