Short-term effects of intravitreal triamcinolone acetonide injection on ocular blood flow evaluated with color Doppler ultrasonography.

摘要: AIM To evaluate the changes in ocular blood flow with color Doppler ultrasonography (CDU) after intravitreal triamcinolone acetonide (IVTA) injection. METHODS A total of 46 patients who underwent IVTA (4 mg/0.1 mL) injection for diabetic macular edema (DME) (n=22), central retinal vein occlusion (CRVO) (n=12) and choroidal neovascular membrane (CNVM) were included study. Peak systolic velocity (PSV), end diastolic (EDV) resistivity index (RI) measured from ophthalmic artery (OA), (CRA) posterior ciliary (PCA) each patient CDU before, at first week month following RESULTS In DME group, PSV OA (mean±SD) (37.48±10.87 cm/s) increased compared to pre-injection value (31.39±10.84 (P=0.048). There was a statistically significant decrease (P=0.049) CRA (7.97±2.67 (9.47±3.37 cm/s). not any difference on other parameters group. Also, there values CRVO CNVM groups. CONCLUSION We observed that 4 mL decreased did have effect patients.
