Purpose: Macular translocation requires extensive retinal manipulation and each step of the surgery may have a potential effect on retinal blood flow status. We investigated whether macular translocation perturbs retinal macrocirculation in long term. Methods: In 9 patients undergoing macular translocation with 360-degree retinotomy, arm-retina time and arteriovenous passage time were quantified from pre- and postoperative scanning laser fluorescein angiogram. The time elapsed between injection into the antecubital vein, and the appearance of the fluorescein at selected two points on superotemporal and inferotemporal arteries near disc provided the arm-retina time. For arteriovenous passage time, 50% of the maximal fluorescence time difference was assessed from the intensity curves of arteries and corresponding veins at the same points for arm-retina time. The data obtained from the superior and inferior temporal quadrant were averaged as a representative macrocirculatory value of the posterior pole. Results: No significant difference was noted between pre- and postoperative values of the arm-retina time (mean ± SD; 14.41 ± 2.73 s vs. 14.70 ± 3.95 s, P = 0.86) or that of the arteriovenous passage time (2.66 ± 0.74 s vs. 2.46 ± 0.65 s, P = 0.55). Degree of retinal rotation around optic disc did not correlate with arm-retina time (r = -0.19, P = 0.62) or arteriovenous time (r = -0.25, P = 0.49). Conclusion: Macular translocation surgery does not have a negative effect on retinal macrocirculation in long term.
