Methods In this randomised, single-blind, parallel controlled trial, children aged 8–12 years with −1.00 to −4.00 D of myopia were recruited. Retinal function was evaluated using global-flash multifocal electroretinography at baseline before OK or SV treatment. Axial length was evaluated at 6-month intervals up to 24 months. The main outcome measures were axial elongation (AE) between groups and the interactive effect of baseline retinal function. Results A total of 70 children (43 OK, 9.8±1.3 years; 27 SV, 9.5±1.4 years) completed the 2-year study and were included in the analysis. The 2-year normalised AE was 0.37±0.37 mm in the OK group and 0.60±0.41 mm in the SV group, respectively. For children in the SV group, the amplitude of the central inner retinal response was negatively correlated with axial length elongation (p=0.03). In contrast, this relationship between retinal electrophysiology and AE was not observed in OK group, indicating that they were independent of each other in children treated with OK (p=0.33). Conclusion A weak retinal electrophysiological response was a risk factor for rapid AE in SV controls. However, OK treatment can lower this risk factor and significantly reduce AE in school-aged children. Data are available upon reasonable request.

Methods Out of the cohort of the population-based Beijing Eye Study (n=3468 participants), the study included all eyes with an axial length of ≥25 mm and a randomised sample of eyes with an axial length of <25 mm. Using optical coherence tomographic (OCT) images and fundus photographs, we examined the presence and height of PSRs, defined as a ridge-like structure located on the OCT scans in the parapapillary region. Results The study cohort consisted of 366 eyes (314 individuals; mean age: 63.7±9.7 years). PSR prevalence increased from 0% in the non-myopic group to 3.8% (95% CI 0.3%, 7.3%) in moderately myopic group and 29.2% (95% CI 15.7%, 42.5%) in the highly myopic group. All PSRs were located in the temporal parapapillary gamma zone and corresponded to an ophthalmoscopically visible demarcation line running almost parallel to the optic disc border. Higher PRS prevalence correlated with longer axial length (OR 2.98; 95% CI 1.99, 4.46; p<0.001), female sex (OR 6.48; 95% CI 1.56, 27.0; p=0.01) and older age (OR 1.09; 95% CI 1.01, 1.18; p=0.02). Axial length had the strongest influence (beta: 0.48), followed by sex (beta: 0.20) and age (beta: 0.14). If age was dropped from the multivariable model, myopic maculopathy prevalence (OR 10.0; 95% CI 1.41,70.9; p=0.02) and stage (OR 3.57; 95% CI 1.21, 10.6; p=0.02) became significantly correlated with higher PSR prevalence. Conclusions With a PSR prevalence of >60% in eyes with an axial length of >28 mm, PSRs are a common morphological feature of high myopia, with age and female sex as additional associated factors. PSRs may be due to a biomechanical interplay between the optic nerve and the posterior ocular segment of markedly axially elongated eyes.
