Purpose: The effects of the blood flow of choroid and macular which plays an important role in the pathogenesis of a central serous chorioretinopathy are unclear. We mearsure and evaluate the blood flow of the the sieve plate and macular in central serous chorioretinopathy with Heidelberg Retinal Flowmetry. Methods: Heidelberg Retinal Flowmetry, which is a system incorporating a noninvasive confocal scanning laser Doppler flow meter, was used to measure the blood flow of of the sieve plate and macular. The study included 39 eyes of 39 patients with central serous chorioretinopathy (mean age: 37.7 +/– 7.8 years), and 48 eyes of 24 age–adjusted normal controls. Results:The blood flow of the sieve plate and macular was significantly decreased (P=0.01) by 41.6% and 39.5%, respectively in the early stage of central serous chorioretinopathy compared to the control group. The blood flow of the sieve plate and macular was not significantly changed in the late stage of central serous chorioretinopathy compared to the control group. There was significant correlation between the sieve plate and macular blood flow(P=0.01).Conclusions:The correlation between the blood flow of the sieve plate and macular is statistically significant in central serous chorioretinopathy.The blood flow of the the sieve plate is correlated with that of choroids.This reveals that the less blood flow of choroids and macular plays an important role in the pathogenesis of a central serous chorioretinopathy.
