Summary: The role of accommodation in myopia development has been debated for decades, with recent studies focusing on the mechanisms involved in accommodation and the variations in ocular parameters. It has been found that convergence is synergistically linked with accommodation and may impact myopia development. Factors like retinal blur, spatial frequency, and near working distance are implicated in myopia progression, while further research is needed to explore the relationship between the ciliary body and changes in the choroid.

Summary: The study found that children experienced exophoric shifts in distance and near vision after switching to ortho-k lenses, along with improvements in accommodative function, stereopsis, and ocular motility, as well as a decrease in the binocular horizontal vergence range.

Summary: Increased higher-order aberrations and improved accommodative accuracy were observed during orthokeratology treatment, but began to regress after the cessation of orthokeratology. A significant positive correlation between improved accommodative accuracy and slowed axial elongation was only observed during the first 6 months of treatment.

Summary: This study evaluated the effects of multifocal soft contact lenses on visual quality, accommodation, and vergence in young adult myopes. The results showed that the two aspheric designs had a greater impact on visual acuity, contrast sensitivity, and accommodation response compared to the concentric design.

Summary: This study characterizes the optical and visual changes in the short-term wear of a hydrophilic contact lens based on extended focus technology. It finds that the lens improves visual acuity and quality but also leads to increased ocular aberrations and a trend of reduced accommodation lag.

Summary: The study aimed to investigate the effectiveness of orthokeratology (ortho-k) lenses for myopia control and the corneal changes with increased compression factor. The findings showed that ortho-k lenses with increased compression factor can effectively slow down the progression of myopia without compromising corneal health. Further research is needed to confirm the potential mechanism of an increased compression factor for improved myopia control effectiveness.

Summary: This study aims to compare the binocular visual functions and balance among monocular myopic adolescents and adults and binocular low myopic adolescents and explore whether monocular myopia requires glasses. The results showed that monocular myopia could lead to accommodative dysfunction and unbalanced input of binocular visual signals, resulting in myopia progression. Furthermore, monocular myopia may also be accompanied by stereopsis dysfunction, and long-term uncorrected monocular myopia may worsen stereopsis acuity in adulthood. Therefore, children with monocular myopia must wear glasses to restore binocular balance and visual functions, thereby delaying myopia progression.

Summary: This study compared the efficacy and safety of corneal refractive therapy (CRT) lenses and vision shaping treatment (VST) lenses for myopia control in children. The results showed that compared with VST lenses, CRT lenses had a weaker effect on myopia control but were safer. Different types of VST lenses had similar efficacy and safety in controlling myopia progression.

Summary: NSAVA was found to be a common cause of vision problems in children attending a paediatric ophthalmology clinic. Children who self-reported reading problems were more likely to have accommodative infacility.

Summary: This study retrospectively investigated the axial length changes in myopic children wearing orthokeratology lenses and found that after initial shortening, the axial length rapidly rebounded during the washout period and shortened again when lenses were re-worn. The changes in axial length were significantly correlated with the initial axial length. Therefore, measuring axial length after the washout period can provide a more objective and accurate evaluation of orthokeratology, and the existence and degree of axial shortening can predict long-term myopia development.

Summary: This study aimed to characterize the changes in corneal refractive power (CRP) during orthokeratology (OK) along the principal corneal meridians. Results showed significant reductions in CRP at the central 4 mm of the cornea, while an increase in CRP was observed in the paracentral zone. The study suggests that peripheral defocus changes after OK may be greater than central corneal power reduction, and CPC power ratios could be used as an alternative method to estimate peripheral defocus.

Summary: This study investigated the effects of an orthokeratology lens on tear film and tarsal glands, as well as myopia control in children with unilateral myopia, using an intelligent analysis model. The study found that tear film break-up times differed significantly in the treatment group, and there were also significant differences in the deformation coefficients of the meibomian glands. In contrast, the control group showed no significant differences.

Summary: Surveys in 2015 and 2019 showed that there was a high level of concern and activity about myopia among eye care practitioners, but most of them still prescribed single vision interventions for young myopes. This research aimed to provide updated information on this topic. The results showed that practitioners in Asia had a significantly higher level of concern about pediatric myopia compared to other continents. Combination therapy was perceived as the most effective method of myopia control, followed by orthokeratology and pharmaceutical approaches, while single vision interventions were seen as the least effective.

Summary: This study found that combining 0.01% atropine with orthokeratology (AOK) has a better effect in retarding axial elongation compared to orthokeratology alone (OK). The study included 96 Chinese children aged 6 to 11 years with myopia and showed that the AOK group had significantly slower axial elongation compared to the OK group. The AOK group also exhibited larger pupil dilation and choroidal thickening.

Summary: Adenoviral conjunctivitis, a common ocular viral infection, lacks approved therapeutic treatments. Povidone-iodine has been used off-label, but evidence supporting its effectiveness is limited. Studies on its use vary widely, making direct comparisons challenging. Investigating optimal concentration, dosing regimen and combination therapy with laboratory techniques could improve treatment outcomes.

Summary: Contact lenses are widely used in clinical practice with various applications and advantages, but they can also lead to complications ranging from innocuous to severe. Clinicians need to prescribe appropriate contact lenses for individual patients and be able to recognize and manage associated complications effectively.

Summary: Myopia is a global epidemic with significant public health impacts. This paper reviews publications that have identified ocular characteristics of children at risk of myopia development and explores risk factors and strategies to prevent myopia onset, such as education exposure and reduced outdoor time. Lifestyle modifications based on the strong causal role of education and outdoor time on myopia development may significantly impact the myopia epidemic by preventing or delaying myopia onset and its associated ocular health consequences.

Summary: This study assessed the impact of patient age on measurement variability for axial length measurements taken with different instruments. The results showed that axial length measurements with the IOLMaster 700 were significantly longer and less variable compared to the IOLMaster 500. However, patient age had no effect on the variability of axial length measurements.
