| Summary: |
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.
Purpose: 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.
Material and methods: 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.
Results: 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. |
