Summary: This study revealed that less than one-third of adults with normal binocular vision were able to successfully free-fuse random-dot image pairs and identify the embedded stereoscopic shapes. The successful participants showed a dissociation of vergence and accommodative responses, while the unsuccessful ones either exhibited strong vergence and accommodation or weak vergence and strong accommodation. Task performance of the unsuccessful cluster improved significantly with pharmacological paralysis of accommodation. A minority of participants also learned to dissociate one direction of their vergence and accommodation crosslinks with repeated free-fusion trials, optimizing their task performance.

Summary: This study aimed to characterize changes in subfoveal choroidal thickness in preterm infants. The results showed that choroidal thickness experienced rapid linear growth from 30 to 38 weeks' postmenstrual age, followed by cessation of growth. Infants with extremely low birth weight and extremely preterm infants had slower growth rates.

Summary: Visual stimuli presented around the time of a saccade can be perceived differently by the visual system, including a reduction in the harmful impact of flankers. This study investigated the effects of microsaccades on crowded stimuli placed 20 arc minutes from the center of gaze. The findings suggest two separate pre-saccadic benefits, one that regularizes the crowding zone and another that specifically benefits microsaccade targets surrounded by tangential flankers.

Summary: Aniridia is a panocular condition characterized by the loss of iris, caused mainly by mutations in the PAX6 gene. This study assessed the effects of Pax6-haploinsufficiency on retinal morphology and vision in Pax6Sey mice. The results showed elevated intraocular pressure and declining visual acuity in Pax6Sey mice, along with local retinal damage and a possible neuroinflammatory response.

Summary: Retinal drusen are uncommon in IgA nephropathy, but they resemble drusen found in age-related macular degeneration. The IgA-staining deposits in the drusen are likely related to systemic deposition of IgA. The nature of cystic spaces in the drusen is still unknown. Further research on the retinas of people with glomerulonephritis is recommended.

Summary: This study examines sociodemographic predictors of poor vision in children and adolescents in the US. The findings suggest that factors such as affordability of medical care, public health insurance, age, and parental education level are associated with vision difficulty. Addressing these disparities through public health policies is crucial for achieving equity in vision health.

Summary: The objective of this study was to investigate the pathogenesis of ocular surface disease associated with the use of dupilumab in patients with atopic dermatitis. The study cohort included 20 patients with moderate-to-severe atopic dermatitis who received dupilumab treatment and 10 healthy controls. The ocular surface microbiome and serum cytokine levels were analyzed. The results showed that some patients developed ocular surface disease after dupilumab initiation, characterized by increased levels of proinflammatory cytokines and a unique microbial landscape on the ocular surface. These findings suggest a potential role of the microbiome in the development of ocular surface disease in patients receiving dupilumab treatment.

Summary: This study investigates the representation of various gender, racial, and ethnic groups in ophthalmology clinical trials conducted in the United States between 1997 and 2022. The findings highlight the need for increased efforts to promote diversity and inclusivity in ophthalmology clinical trials, as there exist disparities in reporting demographic information and enrollment of minorities. Ensuring equitable inclusion of different gender, racial, and ethnic groups in the trials is crucial for minimizing disparities and producing unbiased scientific findings generalizable to the entire population.

Summary: The study aimed to validate or refute the hypothesis that infants with birthweight over 750 g and gestational age over 27 weeks, who did not have retinopathy of prematurity (ROP) at 37 weeks, would not develop treatable ROP. The findings of the study supported the termination of examination at 37 weeks in infants meeting these criteria, as the value of continued screening was minimal.

Summary: This review aimed to estimate the prevalence of computer vision syndrome (CVS) in the general population and subgroups. A meta-analysis of 103 cross-sectional studies with 66 577 participants showed that the prevalence of CVS was 69.0%. Higher prevalence was found in women, university students, Africa and Asia, contact lens wearers, studies conducted before the COVID-19 pandemic, and those that did not use the CVS-Q questionnaire. Standardizing a definition of CVS and implementing preventive strategies and interventions are important for decreasing the prevalence of this condition.

Summary: This study found that a high-fat diet induces endothelial dysfunction in the ophthalmic artery, leading to impaired vascular function in the eye. The high-fat diet triggers oxidative stress and involves RAGE and NOX2.

Summary: This study investigates whether diabetes affects the daily rhythm of gene expression in the retina. The results show that diabetic mice exhibited phase advancement in the expression of certain genes compared to non-diabetic mice. The study also identified oxygen-sensing mechanisms and HIF1alpha as potential upstream regulators. These findings provide important insights into the development of diabetic retinopathy.

Summary: This study aims to evaluate the research productivity of ophthalmology residency applicants and identify differences in productivity based on gender and race. The findings reveal that women have similar or higher research outputs compared to men, while self-identified underrepresented in medicine (URiM) students have lower research outputs in ophthalmology. Therefore, greater mentorship and support for URiM students are needed to promote the recruitment of diverse trainees in ophthalmology programs.

Summary: This study aimed to examine the intraocular tolerability of cetuximab when applied intravitreally, and its effect on axial elongation. The results showed that intravitreal injections of cetuximab could reduce axial elongation in a dose-dependent and number of treatment-dependent manner, without causing intraocular toxic effects.

Summary: We present a new experimental model for inducing retinal ganglion cell (RGC) dysfunction and degeneration in mice. This model allows for the reliable induction of RGC dysfunction and loss, with the resilience of the optic nerve being dependent on the age of the animal. The time-defined nature of the functional and structural changes observed in this model will facilitate the study of glial responses and the evaluation of neuroprotective treatments after intraocular pressure (IOP) injury.

Summary: This study compared the effectiveness of active vision therapy (AVT) and conventional patching therapy in improving visual acuity (VA) and stereoacuity in children with amblyopia. The results showed that AVT had a greater impact on improving stereoacuity compared to patching therapy, but there was no significant difference in terms of VA improvement.
