Change in Choroidal Blood Flow and Choroidal Morphology Due to Segmental Scleral Buckling in Eyes With Rhegmatogenous Retinal Detachment

摘要: Although scleral buckling is a well-established surgical treatment for rhegmatogenous retinal detachment (RRD), the procedure can reportedly cause problems in ocular circulation. Segmental bucking without concomitant encircling was performed on 46 eyes with successfully reattached macula-on RRD. Choroidal blood flow assessed using laser speckle flowgraphy. Spectral-domain optical coherence tomography used to image macular regions, measure subfoveal choroidal thickness (SFCT), and calculate luminal stromal areas by binarization method preoperatively 1, 4, 8 12 weeks postoperatively. mean blur rate at macula did not significantly change, while that buckle unbuckle side reduced postoperatively operated eye (P = 0.007 P = 0.017, respectively). The SFCT area increased temporarily 1 week following surgery (P < 0.001). trend of time coincided Venous drainage obstruction induced compression force leads thickening acute postoperative phase. might be less susceptible because macula, contrast other areas, does change segmental buckling.
