For many years now Doppler's ultrasonography has been broadly applied in ophthalmology. Recently it has been communicated, that there is a possibility of assessing the disorders of retinal circulation in the process of retinal detachment.
Our research had to establish, whether after the scleral buckling treatments executed due to the retinal detachment, there is a change in the blood flow in the vessels of the eyeballs.
The observations were conducted in 30 eyes of 15 people, who were diagnosed with opening-related retinal detachment. The colour Doppler's ultrasonography was performed by using ATL Ultramark 9HDI apparatus with a linear sound of the frequency range from 7.5 to 10 MHz. The anatomic structures of the eye socket in the transverse and arrow plane were assessed. The flow spectrum was measured according to the PD method (pulsating Doppler) in the central artery of the retina at the distance of approximately 2-4 mm from the optic disc and in the ophthalmic artery. The analysis of the spectrum allowed one to determine the values of the pulsation indexes-PI, and resistance indexes-RI, in the ophthalmic artery and in the central artery of the retina of the healthy eye, and of the eye with detached retina 2-3 days before and in 5-7 days after the operative procedure.
After radial and circumferential buckling treatments, the conducted research found no increased resistance of the flow in the arteries, namely: the central artery of the retina and the ophthalmic artery. The condition for the maintenance of the correct parameters of the blood flow was the intraocular pressure. At the same time, in the eyes with detached retina, the decrease in the resistance of the flow in the ophthalmic artery was observed, which was being brought back to normal after the operative treatment.
多年来，多普勒超声检查已在眼科广泛应用。最近有消息称，在视网膜脱离过程中有可能评估视网膜循环障碍。
我们的研究旨在确定因视网膜脱离进行巩膜扣带治疗后，眼球血管中的血流是否发生变化。
对15名被诊断为开放性视网膜脱离患者的30只眼睛进行观察。使用频率范围为7.5至10MHz的线性探头的ATL Ultramark 9HDI设备进行彩色多普勒超声检查。评估眼眶在横向和矢状面的解剖结构。根据PD方法（脉冲多普勒）在距视盘约2 - 4mm处的视网膜中央动脉和眼动脉中测量血流频谱。通过对频谱的分析，可以确定健康眼、视网膜脱离眼在手术前2 - 3天和手术后5 - 7天的眼动脉和视网膜中央动脉的搏动指数（PI）和阻力指数（RI）值。
在进行径向和环向扣带治疗后，研究发现视网膜中央动脉和眼动脉的血流阻力没有增加。维持正确血流参数的条件是眼压。同时，观察到视网膜脱离眼的眼动脉血流阻力降低，手术治疗后恢复正常。
