Ocular Blood Flow in Patients with Complicated Proliferative Diabetic Retinopathy
Abstract
Objective: to study the data of ocular blood flow in patients with different clinical variants of the complications proliferative diabetic retinopathy, and regarding to intraoperative hemorrhagic complications. Material and methods. Through Duplex ultrasonography 62 persons were investigated: 42 (68%) patients (42 eyes) with complicated forms of proliferative diabetic retinopathy and 20 (32%) healthy individuals (20 eyes). Results. The results showed deficiency of retinal blood flow, correlating with the severity of proliferative diabetic retinopathy. The most severe cases of the disease, intraoperative hemorrhagic complications were associated with peak systolic velocity (PSV) reducing (32.14 ± 4.2 cm/s), end-diastolic velocity (EDV) increasing (9.24 ± 2.35 cm/s), resistive index (RI) decreasing (0.71 ± 0.07 cm/s) in ophthalmic artery. Conclusion. The Duplex ultrasonography with the color Doppler imaging and pulced-wave Doppler model can be used for predicting of intraoperative hemorrhagic complications in patients with proliferative diabetic retinopathy.
