Investigation of hemodynamic changes in the ophthalmic artery using color Doppler imaging after strabismus surgery
1Department of Ophthalmology, Chungnam National University College of Medicine, Daejeon, Korea.
Purpose:
We investigated hemodynamic changes in the ophthalmic artery (OA) using color Doppler imaging (CDI) after two horizontal rectus muscles surgery.
Methods:
Eyes of the surgical group (n=18) underwent surgery on two horizontal rectus muscles, and the control group was the contralateral eyes. CDI of the OA was performed before operation and on postoperative days (POD) 1, 7 and 30. Peak systolic (Vmax), end diastolic (Vmin), and mean (Vmean) blood flow velocities were measured, and resistivity index (RI) and pulsatility index (PI) were calculated.
Results:
Vmax, Vmin and Vmean were significantly higher, and RI and PI were significantly lower in the surgical group than in the control group on POD 1 (p<0.05). In the surgical group, Vmax, Vmin and Vmean were significantly higher, and RI and PI were significantly lower, on POD 1 than those measured on other days (p<0.05).
Conclusions:
We showed that surgery on the two horizontal rectus muscles increased OA blood flow during the early postoperative period.
