Article Abstract
Anisometropia is a unique condition of both eyes and it is associated with vision problems such as amblyopia and reduced stereoacuity. Previous studies have not reported its change pattern by age and its correlation with the refractive condition of both eyes. This study aims to compare the changes in anisometropia by age in children with hyperopia, myopia, and antimetropia. In total, 156 children were included. Children aged 3-11 years with anisometropia ≥ 1.00 D were followed up for ≥ 1 year with ≥ 2 visits at two medical centers in Taiwan. Refractive errors by cycloplegic autorefractometry, best-corrected visual acuity, eye position, and atropine use were recorded. The children were divided into hyperopic, myopic, and antimetropic groups. The results showed that anisometropia decreased in children aged < 6 years (3.34-2.96 D; P = 0.038) and increased in older children (2.16-2.55 D; P = 0.005). In children aged 3, 4, 5, and 6 years, the mean anisometropia was higher in children with myopia and antimetropia than in those with hyperopia (P = 0.005, 0.002, 0.001, and 0.011, respectively). The differences were not significant in children aged > 6 years (all P > 0.05). The factors associated with changes in anisometropia were age, refractive group, amblyopia, and strabismus. Anisometropia decreased with age in children younger than 6 years, and the changes in anisometropia was found in children with myopia and antimetropia.

: To study and evaluate the change in retinal nerve fiber layer (RNFL) and macular thickness and its clinical correlation with visual outcome following amblyopia therapy. : In this prospective interventional study, children with moderate to severe amblyopia were given optical correction and part-time occlusion therapy. Visual assessment and optical coherence tomography (OCT) were performed at days 0 and 3, 6 months of follow-up.

Nonsyndromic unicoronal synostosis is associated with variability of severity in orbital morphology and ophthalmological manifestations. The relation between the two is not fully understood, nor how surgical treatment with fronto-orbital advancement and remodelling (FOAR) changes the relation. The aim of this study was to elucidate associations between ophthalmological manifestations and variations in orbital morphology and globe:orbit volume ratios preoperatively and at long-term follow-up after surgery.

Amblyopia is a neurodevelopmental disorder of vision, commonly caused by strabismus or anisometropia during early childhood. While studies demonstrated that perceptual learning improves visual acuity and stereopsis in adults with amblyopia, accompanying changes in visual cortical function remain unclear. We measured functional magnetic resonance imaging (fMRI) responses before and after perceptual learning in seven adults with amblyopia.

Article Synopsis
- The study investigated factors linked to myopia progression and axial elongation in children with myopia.
- It analyzed data from a trial comparing atropine treatment with a placebo, focusing on children aged 5 to <13 with specific refractive errors and other characteristics.
- Results showed that younger children and those with higher initial myopia experienced more significant changes in refractive error and axial length, highlighting the need for treatments to slow progression in this at-risk group.

Article Synopsis
- The study aimed to assess how effective and safe the RLRL treatment is in slowing the progression of high myopia in children aged 7 to 12 years with significant nearsightedness (≥ -6.00 D).
- Conducted as a multicenter, randomized, and single-blind clinical trial, 202 children were divided into two groups: one receiving RLRL treatment plus standard spectacles, and the other receiving only standard spectacles over a 12-month period.
- Results showed that the group receiving RLRL experienced a reduction in both axial length and spherical equivalent refraction, indicating less progression of myopia compared to the control group, along with some positive changes in choroidal and retinal thickness.
