Abstract: Abstract Objective: To discuss morphological character of central serous chori-oretinopathy under 3D-Optical coherence tomography(OCT),and correlation with visual acui-ty.Methods: 46 patients(50 eyes)were checked with 3D-OCT, heights、ranges and values of detachment in macular areas were measured ,and correlation analysisof statistical software SPSS 13.0 was used to calculate correlation between the results abo-ve and visual acuity.Results: There was negative correlation between height of detach-ment in macular areas and visual acuity(r=-0.78,P=0.00),but no correlation between ranges、values and visual acuity(r=-0.39,P=0.26),(r=-0.09,P=0.80).Conclusio-ns: Heights of detachment in macular areas were the main factor infl-uenced visual acuity,high resolution 3D-OCT can get images approaching to hi-stopathology of ophthalmology in CSC affected eyes ,so as to get clinical implications in analyzing diagnosis、Differential Diagnosis 、degrees of disease and were most valuable in supervison after the therapy.
