[A new method of duplex ultrasonic examination of the state of blood supply to the ciliary body].
Duplex ultrasonic scanning was used to examine blood supply to the ciliary body. The study helped quantitatively assess the ciliary body hemodynamics. The hemodynamic parameters in diseases of the anterior segment of the eye (cataracts, glaucoma, corneal dystrophy, etc.) significantly differed from the norm: pulsative index 2.32 vs. the normal value of 1.57, systolic/diastolic ratio 7.29 vs. 6.23, the peak systolic rate 12.59 cm/sec vs. 34.36 cm/sec, maximal rate 6.56 cm/sec vs. 14.36 cm/sec, mean rate 4.0 cm/sec vs. 8.76 cm/ces, volumic rate 1.47 ml/min vs. 3.66 ml/min. The examinations helped detect early disorders in the blood supply to the ciliary body. New ultrasonic equipment: Quantascope (Vital Science, England) and DRF-1000 (Piasonics, USA) was used, that proved highly informative and reliable.
