The detection of the bulbar conjunctival microcirculation (BCM) of 73 cases (146 eyes) with retinitis pigmentosa (RP) showed that there were some abnormal changes of BCM in the pathologic progress of RP. The older the patient, the longer the disease history and the more the loss of visual field, the more serious the abnormal changes of BCM. The disease in male patients was in general more serious than in female patients. Its characteristics were the followings: increase in the number of tortuous vessels; the different widths of vessels in a few cases; obvious increase of microangioma; abnormal proportion of artery to vein; decelerated blood flow and aggregated erythrocytes. Some abnormal changes in the nailfold microcirculation (left ring finger) were observed in the meantime, and compared with those in the BCM of 56 cases. It was found that they were positively interrelated (gamma's = 0.9965, P < 0.001).
对73例（146只眼）视网膜色素变性（RP）患者的球结膜微循环（BCM）检测显示，在RP的病理进程中BCM存在一些异常变化。患者年龄越大、病程越长、视野缺损越多，BCM的异常变化就越严重。男性患者的病情总体上比女性患者更严重。其特征如下：迂曲血管数量增加；少数病例中血管宽度不同；微血管瘤明显增多；动静脉比例异常；血流速度减慢和红细胞聚集。同时观察了甲襞微循环（左手无名指）的一些异常变化，并与56例BCM的变化进行了比较。发现它们呈正相关（γ = 0.9965，P < 0.001）。
