Abstract
Purpose: :
Blood flow in central retinal artery is reported to decrease in rhegmatogenous retinal detachment (RRD). Laser speckle flowgraphy (LSFG) (LSFG-Navi, Softcare, Fukuoka, Japan) is a new instrument for visualizing and measuring blood flow in ocular fundus, make it easy to evaluate retinal blood flow and is very suitable for clinical application. We evaluated retinal blood flow with LSFG in RRD patients before and after surgical treatments.
Methods: :
Sixteen male and Nineteen female patients (mean age 53 years, ranging from 11 to 80) with RRD were included in this study. Preoperative and postoperative (1 month later, 3 months later) retinal blood flow were measured using LSFG at Nagasaki University Hospital. Mean blood velocity expressed as mean blur rate (MBR) of large vessels at optic disc was evaluated. Cases of poor measurement (cataract with sever cortex opacity, vitreous hemorrhage, poor mydriasis, etc) were excluded.
Results: :
Sixteen male and Nineteen female patients (mean age 53 years, ranging from 11 to 80) with RRD were included in this study. Preoperative and postoperative (1 month later, 3 months later) retinal blood flow were measured using LSFG at Nagasaki University Hospital. Mean blood velocity expressed as mean blur rate (MBR) of large vessels at optic disc was evaluated. Cases of poor measurement (cataract with sever cortex opacity, vitreous hemorrhage, poor mydriasis, etc) were excluded.
Conclusions: :
Mean blood flow measured by LSFG at optic disc significantly decreased in RRD patients and recovered after successful surgical treatment. MBR at optic disc may be useful to evaluate inretinal circulation RRD.
