Using high-resolution duplex scanning it is possible to evaluate the blood flow velocity in the central retinal artery of the eye. Four different patient groups were studied with this technique: normals, diabetics with a decreased flow, diabetics with an increased flow and vascular patients with a decreased flow. The eyes of these patients were then treated with topical timolol and the flow measured again. An increase in the flow was found in three of the four groups. This increased flow velocity may be due to a vasodilatory effect of timolol. The results are presented and discussed.
使用高分辨率双功扫描可以评估眼部视网膜中央动脉的血流速度。用该技术对四组不同的患者进行了研究：正常人、血流减少的糖尿病患者、血流增加的糖尿病患者以及血流减少的血管疾病患者。然后对这些患者的眼睛局部应用噻吗洛尔进行治疗，并再次测量血流。在四组中的三组中发现血流增加。这种血流速度的增加可能是由于噻吗洛尔的血管舒张作用。现将结果呈现并进行讨论。
