Abstract

Purpose: To evaluate retinal blood velocity by laser speckle flowgraphy (LSFG) after rhegmatogenous retinal detachment (RRD) surgery, and compare the results obtained from patients who had either primary vitrectomy or scleral buckling.

Methods: Subjects included 57 patients (57 eyes) who had undergone surgery for unilateral RRD from May 2010 to August 2012. Preoperative and 1-and 3-month postoperative retinal blood velocities were measured as Mean Blur Rate (MBR) at the optic disc by LSFG. The ratio (%) of MBR in the affected eye to the fellow eye was compared.

Results: 23-gauge pars plana vitrectomy without buckling was performed in 36 patients, local buckling without vitrectomy was performed in 13 patients, encircling buckling without vitrectomy was performed in 8 patients. The average MBR in vitrectomy group significantly increased 1-month after operation (121.42% ± 39.03% P<0.05), 3-month after operation (130.43% ± 36.18%; P<0.01). However the average MBR in scleral buckling group not changed 1-month after operation (101.80% ± 41.82%), 3-month after operation(106.99% ± 37.08%).

Conclusions: Vitrectomy and scleral buckling may have different effects on retinal circulation. LSFG may be useful to evaluate hemodynamics after successful treatment in RRD.
