Summary: This study investigated the refractive profile in individuals with ocular albinism (OA) and oculocutaneous albinism (OCA) based on a large dataset. The results showed that individuals with albinism commonly had hyperopia and myopia, with very few having emmetropia. The frequency of hyperopia and myopia was significantly higher than emmetropia across all age groups. Additionally, with-the-rule astigmatism and nystagmus may contribute to impaired normal refractive development in individuals with albinism.

Summary: This study investigated the relationship between myopia progression and axial length elongation in orthokeratology patients. The results showed that myopia significantly progressed and axial length increased after ortho-k treatment, and this progression was related to changes in corneal curvature, baseline age, and duration of treatment.

Summary: There is a negative correlation between ocular refraction and axial length in Chinese university students, with a stronger correlation coefficient observed in individuals with moderate to high myopia compared to those with low hyperopia to emmetropia. Additionally, men have longer axial lengths compared to women.

Summary: The study evaluated the prevalence of myopia and the light environment in Aracati, Brazil, finding the mean spherical equivalent and axial length, as well as the prevalence of myopia and high myopia among schoolchildren in the region. Lifestyle factors were not associated with myopia, but the light environment may have an impact on axial length and refractive errors.

Summary: In this study of elementary school-aged children in Singapore, various sleep factors such as quality, duration, timing, and consistency were not independently associated with myopia, spherical equivalent, and axial length. Large longitudinal studies are needed to verify these results.

Summary: The study demonstrates that chronic ocular hypertension can accelerate the development of slowly progressive myopia in Long-Evans rat eyes, accompanied by an initial increase in eye structure and function that later reverses.

Summary: The purpose of this study was to investigate choroidal and ocular biological variables that influence axial length elongation in myopic children wearing defocused incorporated multiple segments spectacle lenses. The results showed that the area of choriocapillaris flow voids and age were significantly associated with axial length elongation. Further analysis indicated that larger choriocapillaris flow voids area, age, and average K reading were associated with axial length elongation. These findings help predict axial elongation in myopic eyes.

Summary: This study compared axial and peripheral eye elongation during myopia therapy with multifocal soft contact lenses. The findings suggest that wearing +2.50 D addition multifocal contact lenses can neutralize or reverse the increase in retinal steepness caused by single vision lenses.

Summary: Unilateral orthokeratology lenses effectively reduced axial elongation in the more myopic eyes and reduced interocular AL differences in children with myopic anisometropia. The refractive state of the untreated eyes did not affect the axial elongation of the more myopic eye wearing the orthokeratology lens. In the untreated eyes, AL increased faster in the low myopia subgroup than in the emmetropia subgroup.

Summary: This study investigated the distribution of visual acuity, refractive error, and axial length in 8-year-old children participating in the Japan Environmental Children's Study. The results showed that males had significantly longer axial length compared to females, and there was a significant correlation between axial length, spherical refractive error, and uncorrected visual acuity. Additionally, children with a parental history of eyeglasses or contact lens wear had significantly more myopic refractive error.

Summary: This study investigates the impact of the refractive error gene GJD2 on human myopia, finding that it affects ocular biometry, particularly axial length and anterior chamber depth. Children carrying two risk alleles show larger axial length/corneal radius ratio at ages 6 and 9. Education and environmental factors negatively influence myopia and biometric outcomes, though gene-environment interactions do not reach statistical significance.

Summary: This study described the distribution of ocular biometry and refraction in Japanese adults using data from a large cohort study. The prevalence of myopia and high myopia was higher during the study period compared to earlier studies, indicating recent environmental changes. However, the prevalence of extreme myopia remained stable across all ages, suggesting a strong genetic predisposition to this phenotype.

Summary: The International Myopia Institute (IMI) is focused on advancing research, education, and management in the field of myopia to reduce the incidence of future vision impairment and blindness associated with increasing myopia. By promoting collaboration and knowledge sharing, IMI addresses issues such as pathologic myopia, the impact of myopia, risk factors, accommodation, binocular vision, and myopia prevention.

Summary: Optic disc crescents are one of the first clinically observed changes in the retina with progressing myopia. This study investigated the type, dimension, and appearance of crescents and their relationship with the level of myopia. The results showed a significant correlation between crescent width and age, and eyes with inferior temporal crescents were more myopic.

Summary: The purpose of this study was to investigate whether axial growth and refractive error can be modulated in anisohyperopic children by using multifocal soft contact lenses. The results showed that imposing relative peripheral hyperopic defocus did not accelerate axial growth nor reduce refractive error in anisohyperopic children.

Summary: This study utilized 3D magnetic resonance imaging to investigate the regional variations in surface area and bulbosity of four anterior segment regions of the human eye, and their association with refractive status, axial length, and total ocular volume. The results showed significant regional differences in surface area, with myopic individuals having smaller surface areas in certain quadrants.
