Abstract

Objective

To investigate the features of multicolor imaging in the macular region of central serous chorioretinopathy (CSC) patients.

Methods

A cross-sectional study was conducted.Thirty-four acute CSC patients (34 eyes) treated in Renmin Hospital of Wuhan University from August 2017 to January 2018 were enrolled.Among the 34 subjects, there were 21 males (21 eyes) and 13 females (13 eyes). The subjects were 26 to 61 years old, with an average age of (37.41±9.35) years.The course of the disease was 5 to 45 days, with an average course of (12.00±2.29) days.All the subjects were examined by color fundus photography, fluorescein angiography (FFA), indocyanine green angiography (ICGA), multicolor imaging, spectral-domain optical coherence tomography (SD-OCT). The image features of each patient were compared and analyzed.The diagnostic accordance rate for leakage point and serous retinal neuroepithelial detachment of multicolor imaging and color fundus photography was calculated according to FFA/ICGA and OCT.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2019-K037).

Results

The serous retinal detachment region showed green light reflection area with clear boundary in 33 eyes (97.06%) in the standard as well as blue and green enhanced multicolor image, with not clear boundary in 1 eye (2.94%). The serous retinal detachment region showed weakly reflective area in 17 eyes (50%) in blue reflectance image, showed weak reflection with clear boundary in 32 eyes (94.11%) in green reflectance image, showed weakly reflection with clear boundary in 33 eyes (97.06%) in infrared reflectance image.The fluorescein leakage point in FFA image was found micro retinal pigment epithelium detachment (PED) in 19 eyes (55.88%), rough light band of retinal pigment epithelium (RPE) in 12 eyes (35.29%), and large PED in 3 eyes (8.82%) in SD-OCT image.The RPE leakage showed red mottled changes in the area of neuroepithelial detachment in 29 eyes (85.29%) in the standard as well as blue and green enhanced multicolor images, presented strong reflection spots in blue reflectance images in 2 eyes (5.88%), showed strong reflective spots in green reflectance in 5 eyes (14.70%), showed strong reflection spot in the weakly reflective area in 33 eyes (97.06%) in infrared reflectance images.Taking FFA/ICGA and OCT as the gold standard, the diagnostic accordance rate of standard multicolor, blue and green enhanced multicolor and infrared reflectance images for serous retinal neuroepithelial detachment and leakage points was higher than that of color fundus photography, and the differences were statistically significant (all at P<0.05).

Conclusions

Standard multicolor, blue and green enhanced multicolor and infrared reflectance images can reflect the leakage point and retinal neuroepithelial detachment of acute CSC.Green reflectance image can show serous retinal neuroepithelial detachment of acute CSC.Multicolor imaging can be used as the auxiliary diagnosis method of acute CSC.
