[The observation of the bulbar conjunctival microcirculation in patients with retinitis pigmentosa].
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).
