Background: As COVID-19 occurs suddenly and is highly contagious, this will inevitably cause people anxiety, depression, etc. The study on the public psychological states and its related factors during the COVID-19 outbreak is of practical significance. Methods: 600 valid questionnaires were received. The Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS) were used. Results: Females’ anxiety risk was 3.01 times compared to males (95% CI 1.39–6.52). Compared with people below 40 years old, the anxiety risk of people above 40 years old was 0.40 times (95% CI 0.16–0.99). SDS results indicated that the difference between education level and occupation was statistically significant (p = 0.024, 0.005). Compared to people with a master’s degree or above, those with a bachelor’s degree group had a depression risk of 0.39 times (95% CI 0.17–0.87). Compared with professionals, industrial service workers and other staff had a depression risk of 0.31 times (95% CI 0.15–0.65) and 0.38 times (95% CI 0.15–0.93). Conclusions: 600 questionnaire participants were psychologically stable. Non-anxiety and non-depression rates were 93.67% and 82.83%, respectively. There were anxiety in 6.33% and depression in 17.17%. Therefore, we should pay attention to the psychological states of the public.

Retinal and optic nerve diseases have become the most common causes for irreversible vision loss globally.¹ Their diagnosis relies on the availability of experienced ophthalmologists, however, the density of ophthalmologists varies within countries and regions. For example, there are approximately 40 000 registered ophthalmologists in China with a higher density in east China than in west China.² In addition, the clinical experience of ophthalmologists varies, which further increases the unbalanced distribution of personal resources in ophthalmology.³ These regional differences limit the possibility of people living in underdeveloped regions to have regular screening for retinal diseases.

Purpose: To examine the relationships between axial length and foveal and peripheral retinal thickness. Methods: Using optical coherence tomography, foveal retinal thickness was measured in participants of the population-based Beijing Eye Study without optic nerve or macula diseases. Inner and outer nuclear layer thickness as surrogate for retinal thickness was assessed in the fundus periphery in human globes enucleated due to malignant uveal melanoma or painful glaucoma. Results: The study included 1117 individuals with a mean age of 64.2 ± 9.7 years (range: 50–93 years) and mean axial length of 23.4 ± 1.04 mm (range: 20.29–28.68 mm). In multivariate analysis, thicker central foveal thickness was associated with male sex (P < 0.001; standardized regression coefficient beta: −0.13; nonstandardized regression coefficient B: −5.84; 95% confidence interval (CI): −8.56, −3.13); urban region of habitation (P = 0.02; beta: 0.07; B: 3.56; 95% CI: 0.55, 6.57); thinner lens thickness (P = 0.01; beta: −0.08; B: −5.11; 95% CI: −9.01, −1.21); thinner subfoveal choroidal thickness (P = 0.04; beta: −0.07; B: −0.01; 95% CI: −0.03, −0.001); and longer axial length (P < 0.001; beta: 0.18; B: 3.79; 95% CI: 2.41, 5.17). In the same multivariate model, superior, inferior, and temporal foveal thickness was not significantly associated with axial length (P = 0.26, P = 0.19, P = 0.08, respectively), while thicker nasal foveal thickness was associated with longer axial length (P = 0.009; beta: 0.09; B: 1.50; 95% CI: 0.37, 2.62). In the histomorphometric part of the study including 32 eyes (sagittal diameter: 27.0 ± 4.2 mm; range: 22–37 mm), mean thickness of the inner and outer nuclear layers at the equator and at the midpoint equator/posterior pole decreased with longer axial length (P = 0.004; beta: −0.48; and P = 0.02; beta: −0.44, respectively). Conclusions: Myopic axial globe elongation was associated with retinal thinning in the equatorial and pre-equatorial region, while foveal retinal thickness was mostly unaffected by axial length. It suggests that axial elongation takes place predominantly in the equatorial and pre-equatorial region of the eye.
