Abstract
PURPOSE:To quantitatively evaluate the relationship between retinal microstructure and prognosis in patients with central serous chorioretinopathy(CSC) using optical coherence tomography(OCT).METHODS:Three hundred and ninty-eight affected eyes of patients with central serous chorioretinopathy were included in this retrospective study. The OCT images of all patients were analyzed in baseline, and logistic regression analysis were performed with 11 independent variables, and subretinal fluid absorption in 3 months after therapy as dependent variable. The correlation between shortage of ellipsoid baseline and height of foveal subretinal fluid, width of foveal subretinal fluid were analyzed respectively. The difference of duration and baseline logMAR visual acuity in eyes with and without double layer sign or subretinal hyper-reflective materials were analyzed respectively. The difference of therapeutic outcome among different therapeutic methods was also analyzed in eyes with double-layer sign and subretinal hyper-reflective materials respectively.RESULTS:In the regression analysis with subretinal fluid absorption in 3 months after therapy as dependent variable, disintegrity of ellipsoid zone was statistically significant(P<0.0001,B=1.288). There is no correlation between disintegrity of the ellipsoid zone and the width or height of subretinal fluid. The duration of disease in eyes with double layer sign or subretinal hyper-reflective materials was longer than those without these features(P<0.001, P<0.0001). In the eyes with the double-layer sign or subretinal hyper-reflective material, the difference of logMAR visual acuity 3 months after treatment between 2 therapeutic methods was not statistically significant.CONCLUSIONS:Using optical coherence tomography to evaluate microstructure changes in eyes with central serous chorioretinopathy quantitatively, we found that subretinal fluid was easier to absorb completely in eyes with less disintegrity of ellipsoid zone. Double layer sign and subretinal hyper-reflective materials are more common in eyes with longer duration of disease.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
