摘要：The aim of the present study is to evaluate the potential statistically significant differences in the ocular blood flow parameters in eyes with rhegmatogenous retinal detachment (RD). Eleven patients, 5 females and 6 males, mean age 46 years (range 22–70), with the unilateral rhegmatogenous RD were enrolled in the study. Colour Doppler Ultrasound was used to measure ocular blood flow velocities in the ophthalmic artery (OA), posterior ciliary’s arteries (PCA) and ophthalmic vein (OV). The contralateral eye served as a control. All Doppler examinations were performed 1 day before and exactly 3 days after the retinal detachment surgery. The measurements of the peak systolic velocity (Vmax), diastolic velocity (Vd), minimum velocity (Vmin), time-averaged velocity (TAV), resistive index (RI) and pulsatility index (PI) showed no statistically significant difference (by paired Student's t-test, p>0.05) between the OA, PCA and OV in healthy eyes and eyes with RD before operation, as well as between the eyes with RD before and after the operation. Only was increased RI in OV of eyes with RD after the surgery (p more quadrants of RD, but the difference in duration of retinal detachment in days is statistically significant (by Wilcoxon t-test p>0.05). Pearson correlation method gave statistically significant correlation between RI and PI of the OA in healthy eyes (r =0.826, p (r=0.856, p three cases. Scleral buckling surgery leaves the ocular blood parameters in OA unchanged. The correlation between RD and logarithm of duration of RD in days is statistically significant.
