Cases of myopia have recently increased, and high myopia has become a concern because it can cause various eye disorders and eventually lead to blindness. Myopia has been reported to be associated with environmental and genetic factors, and therefore, early intervention is critically important for prevention of progression to high myopia. Optical, pharmacological, and environmental approaches have been tried as preventive measures against myopia progression, and each has demonstrated a certain effect in several studies. In this review, the most updated information on the methods for myopia control is introduced with details of each approach.

Purpose: To quantitatively compare the visual field (VF) results measured by orthoptists and students on simulated patients using a training system for the Goldmann perimeter, and to clarify the differences between them.

Methods: Eight orthoptic students and five orthoptists with >5 years of clinical experience in ophthalmology participated in this study. The participants performed VF tests on a simulated patient with glaucomatous changes using the system. The isopter of V/4e, I/4e, I/3e, I/2e and I/1e was calculated using plot points recorded by the participant. The union area (UA), intersection area (IA), symmetric difference area (SDA) and intersection percentage were analyzed by superimposing the VF data detected by the study participants and the simulated patient’s data.

Results: IA was significantly narrower, and SDA was significantly wider in orthoptic students than in orthoptists.

Conclusions: Orthoptists more accurately measured the VF than orthoptic students.

[Purpose] To examine the relationship between body height development and refractive error (RE) change in school-age children.

[Subjects and Methods] In 1261 eyes of 642 children who “detailed visual acuity test” between elementary-school Grade 1 to junior-high-school Grade 2 from 2016 to 2019, changes in RE was examined by binocular open-field autoref keratometer under non-accommodated paralysis and spherical equivalence was calculated. Body height data was obtained from questionnaire responses. Grade and gender was classified into 14 groups. The relationship between RE change and body-height change in each group was examined.

[Results] A significant correlation was found between RE change and body-height change in Grade 6 elementary to Grade 1 junior high school boys (r = −0.27, p = 0.005) and Grade 4–5 elementary school girls (r = −0.32, p = 0.003).

[Conclusion] Correlation between RE change and body height was found in upper-grade-elementary to junior-high boys and middle to upper-grade-elementary girls.
