[The effect of retrobulbar injection with anisodamine on ocular blood velocity in anterior ischemic optic neuropathy].

Objective: To study the effect of retrobulbar injection with anisodamine on ocular blood velocity in anterior ischemic optic neuropathy (AION).

Methods: 15 minutes before injection, 15 minutes and 1 hour after injection, the blood flow velocity in 39 cases (39 eyes) diagnosed as AION was measured and analyzed by CDI, timed average maximum velocity, peak systolic velocity, end diastolic velocity, resistance index and pulsatility index of OA, CRA and PCA were recorded.

Results: Compared with the normal eyes, each parameter of SPCA was statistically significant.

[Color Doppler flow imaging in the diagnosis of complex vitreoretinal diseases].

Objective: To investigate the advantages of Color Doppler flow imaging (CDFI) in the diagnosis of complex vitreoretinal diseases.

Methods: Both CDFI and B-mode ultrasonographic studies were performed on 518 cases (678 eyes) vitreoretinal diseases, such as vitreous hemorrhage, posterior vitreous detachment, vitreoschisis, retinal detachment; choroidal detachment and diabetic vitreoretinopathy. The accuracy of diagnosis by B-mode and CDFI on the same case was compared with results of surgery.
