Abnormal zinc and copper metabolism have been described in several retinal disorders affecting the retinal pigment epithelium. An infrequent presentation of senile macular degeneration in high myopia is well known. We examined the blood for zinc and copper and the urine for copper of three groups of patients, one consisting of high myopia, another with high myopia and primary retinal detachment and the other a group of patients with senile macular degeneration. When comparing the above groups of patients, we found statistically elevated values of serum zinc (p = less than 0.005) in the group of patients with senile macular degeneration. The significance of these findings, and a correlation with the pathogeneses of high myopia and senile macular degeneration is discussed.

Importance: For myopia control to be beneficial, it would be important that the benefit of treatment (slowed eye growth) is not lost because of faster than normal growth (rebound) after discontinuing treatment.
Objective: To determine whether there is a loss of treatment effect (rebound) after discontinuing soft multifocal contact lenses in children with myopia.
Design, Setting, And Participants: The Bifocal Lenses in Nearsighted Kids 2 (BLINK2) cohort study involved children with myopia (aged 11-17 years at BLINK2 baseline) who completed the BLINK Study randomized clinical trial.

Purpose: The purpose of this study was to evaluate the correlation between axial length (AL) and retinal oxygen dynamic parameters in adult patients.
Methods: This was an observational cross-sectional study with 79 Chinese adults with myopia aged 18 to 37 years. All participants underwent AL measurements, cycloplegic refraction, and other ophthalmic examinations.
Influence of Lens Power on IOL/Posterior Lens Capsule Interactions and IOL's PCO Potential.

Purpose: Severely myopic eyes have been associated with high posterior capsule opacification (PCO) incidence. Although it has been reported that myopic eyes have weaker or more delayed capsule adhesion than emmetropic eyes, it is unclear whether/how dioptric power and posterior curvature of IOLs affect IOLs' affinity for the posterior lens capsule (PLC) and their PCO potential.
Methods: To investigate this, acrylic foldable IOLs with increasing dioptric power of 6.
Biochemical components of corneal stroma: a study on myopia classification based on Raman spectroscopy and deep learning methods.
Biomed Opt Express

Center for Biomedical-photonics and Molecular Imaging, Advanced Diagnostic-Therapy Technology and Equipment Key Laboratory of Higher Education Institutions in Shaanxi Province, School of Life Science and Technology, Xidian University, Xi'an, Shaanxi 710126, China.
The study aimed to identify differences in the biochemical composition of corneal stroma lenses across varying degrees of myopia using Raman spectrum characteristics. Corneal stroma lens samples from 38 patients who underwent small incision lens extraction (SMILE) surgery, were categorized into low (n = 9, spherical power -3.00D), moderate (n = 23, spherical power < -3.

Introduction And Primary Objective: Pediatric rhegmatogenous retinal detachment (RRD) presents unique challenges in diagnosis and management. A thorough evaluation of family, medical, and ocular history is helpful, as systemic and genetic conditions can predispose children to RRD. Trauma, high myopia, and history of prematurity are also common risk factors.
