AIM： To compare the peripapillary retinal nerve fiber layer（RNFL） thickness measured via optical coherence tomography（OCT） between different groups of myopia severity and controls. METHODS： This was a prospective cross-sectional study. All subjects underwent a full ophthalmic examination, refraction, visual field analysis and A-scan biometry. Myopic patients were classified as low myopia（LM） [spherical equivalent（SE） from greater than-0.5 D, up to-3.0 D], moderate myopia（MM; SE greater than-3.0 D, up to-6.0 D） and high myopia（HM; SE greater than-6.0 D）. The control group consisted of emmetropic（EM） patients（SE from ＋0.5 D to-0.5 D）. A Zeiss Cirrus HD-OCT machine was used to measure the peripapillary RNFL thickness of both eyes of each subject. The mean peripapillary RNFL thickness between groups was compared using both analysis of variance and analysis of ***： A total of 403 eyes of 403 subjects were included in this study. The mean age was 31.48±10.23 y. There were 180（44.7%） eyes with EM, 124（30.8%） with LM, 73（18.1%） with MM and 26（6.5%） with HM. All groups of myopia severity had a thinner average RNFL than the EM group, but after controlling for gender, age, and axial eye length, only the HM group differed significantly from the EM group（P=0.017）. Likewise, the superior, inferior and nasal RNFL was thinner in all myopia groups compared to controls, but after controlling for confounders, only the inferior quadrant RNFL was significantly thinner in the HM group, when compared to the EM group（P=0.017）. CONCLUSION： The average and inferior quadrant RNFL is thinner in highly myopic eyes compared to emmetropic eyes. Refractive status must be taken into consideration when interpreting the OCT of myopic patients, as RNFL thickness varies with the degree of myopia.

Separable nonlinear models are widely used in various fields such as time series analysis, system modeling, and machine learning, due to their flexible structures and ability to capture nonlinear behavior of data. However, identifying the parameters of these models is challenging, especially when sparse models with better interpretability are desired by practitioners. Previous theoretical and practical studies have shown that variable projection (VP) is an efficient method for identifying separable nonlinear models, but these are based on \(L_2\) penalty of model parameters, which cannot be directly extended to deal with sparse constraint. Based on the exploration of the structural characteristics of separable models, this paper proposes gradient-based and trust-region-based variable projection algorithms, which mainly solve two key problems: how to eliminate linear parameters under sparse constraint;and how to deal with the coupling relationship between linear and nonlinear parameters in the model. Finally, numerical experiments on synthetic data and real time series data are conducted to verify the effectiveness of the proposed algorithms.
