Abstract

Objective

To explore the application of multispectral fundus imaging (MSI) in central serous chorioretinopathy (CSC).

Methods

A diagnostic test study was conducted.Eighty-five eyes from 69 patients with macular diseases were enrolled in Renmin Hospital of Wuhan University from September 2017 to May 2018.There were 62 males (77 eyes) and 7 females (8 eyes) among the 69 patients with an average age of (48.0±11.2) years.The patients were divided into CSC group (45 cases, 61 eyes) and non-CSC group (24 cases, 24 eyes) according to whether suffering from CSC or not.Color fundus photography, fundus fluorescein angiography (FFA), indocyanine green angiography, spectral domain-optical coherence tomography and MSI were performed in the two groups and the images were collected.With FFA as the gold standard, the sensitivity, specificity, false positive rate, false negative rate, positive predictive value and negative predictive value of MSI in the diagnosis of CSC were calculated.Kappa consistency test was used to evaluate the consistency of MSI and FFA in diagnosing CSC, and to evaluate the diagnostic value of MSI in CSC.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). Written informed consent was obtained from each subject prior to any medical examination.

Results

The sensitivity, specicity, false positive rate, false negative rate, positive predictive value and negative predictive value of MSI for identifying CSC were 88.5%, 91.7%, 8.3%, 11.5%, 96.4% and 75.9%, respectively.The Kappa coefficient of agreement was 0.754.There was no significant difference in the identification of CSC between MSI and FFA (χ2=1.780, P=0.180). Hyper-reflective signals corresponding to the leakage points were better detected with MSI images at 620-850 nm wavelength.The clear boundary of serous neuroepithelial detachment area was better detected with MSI images at 590-810 nm wavelength.The retinal pigment epithelium damage was better detected with MSI images at 660-850 nm wavelength.

Conclusions

There is a good consistency between MSI and FFA.MSI can be an effective noninvasive inspection method for CSC.
