摘要
目的 探讨视网膜色素变性 (RP)患者视网膜血流的改变情况。方法 用共焦激光扫描多普勒血流仪 (CSLDF)对 3 3例RP患者和 2 6例正常个体视乳头筛板区、颞侧盘沿和颞侧、鼻侧距盘缘约 1 50 μm处 (各两点 )的血管容量、血液流量及红细胞平均移动速率分别进行了测定。结果 RP患者组视乳头筛板区、颞侧盘沿和颞侧、鼻侧近盘周视网膜的血管容量、血液流量、红细胞平均移动速率均较正常对照组下降 ,且差异具有显著性意义 (P <0 0 5)。结论 RP患者视乳头筛板区、颞侧盘沿和近盘周视网膜血流明显降低。
OBJECTIVE To study the retinal blood flow changes in patients with retinitis pigmentosa(RP).METHODS Blood vessel volume, quantity of blood flow, and mean velocity of erythrocyte were determined in 33 patients with RP and 26 control subjects by confocal scanning laser Doppler flowmeter (CSLDF) in the lamina cribrosa, temporal disc rim, and the retina approximately 150μm from the edge of the optic disc (two points at temporal, and two points at nasal ). RESULTS Compared to control subjects , blood vessel volume, quantity of blood flow, and mean velocity of erythrocyte in the lamina cribrosa, temporal disc rim, and the retina of the patients with RP were reduced significantly ( P <0 05). CONCLUSIONS Blood flow in the lamina cribrosa, temporal disc rim, and the retina of the patients with RP were reduced significantly.
