Wstęp
To assess the macular microcirculation blood flow with Doppler laser scanning (HRF – Heidelberg Retinal Flowmeter), in patients with complicated rhegmatogenous retinal detachment (RRD), after pars plana vitrectomy (PPV), with silicone oil tamponade.

Materiał i metody
Eleven patients (6 males and 5 females), aged 38-64 years, mean age: 52.4 years, with unilateral macula-on complicated RRD were included in a study. In all cases conventional (20-gauge) pars plana vitectomy with silicone oil tamponade was performed. Control group consists of the fellow eyes.

Wyniki
In the early postoperative period (1-3 days after surgery), in all operated eyes the mean values of macular microcirculation blood flow were significantly reduced in the comparison with those of the control eyes (p = 0.01). The reduction of mean values of macular microcirculation blood flow was still observed in all silicone-oil-filled eyes one month after surgery as compared to the contralateral eyes (p = 0.01). There was no correlation between the values of macular microcirculation blood flow and the duration of RRD, baseline BCVA, refractive error, number of retinal tears, and the patient age.

Wnioski
The preliminary results of this study suggest that PPV with silicone oil tamponade influences over the retinal blood flow. We have observed that silicone oil may have a negative long-term effect on the retinal microcirculation as it was noted one month after surgery.
