Summary: In this study, associations between different OCT metrics of the choroid in healthy subjects were assessed. The analysis revealed a quadratic relationship between choroidal luminal and stromal areas and choriocapillaris flow deficits, indicating an initial increase in perfusion with changes in these areas. Non-linear associations were not found between choriocapillaris flow deficits and the choroidal vascularity index.

Summary: This study investigated the topographical and within-day changes in choroidal vascularity index (CVI) and its association with choroidal thickness parameters among young adults. The results showed significant regional variations in choroidal thickness parameters, with thicker choroid in the superior region. Myopia was associated with thinner choroidal thickness, and high myopes exhibited reduced within-day change amplitudes in stromal choroidal thickness. The findings highlight the importance of considering choroidal vascularity and thickness in understanding the ocular characteristics of young adults.

Summary: The study investigated the reflectivity of the inner choroid and found that the reflectivity changes with age, with increasing compaction of collagen fibers in the choroidal stroma. This suggests that the optical coherence tomography reflectance from the inner choroid is related to the packing density of collagen fibers present there.

Summary: This study evaluated the choroidal vascularity index (CVI) in central serous chorioretinopathy (CSC) and found that CVI is increased in acute CSC eyes and fellow eyes. There was no significant difference in CVI between acute and chronic CSC eyes. The area selected for CVI calculation may influence the outcomes of the study and requires further research.

Summary: Optical coherence tomography (OCT) imaging is a crucial tool in the field of retina, providing non-invasive, high-quality cross-sectional analysis of the retina and revolutionizing the diagnosis and treatment of retinal and choroidal diseases. Recent advances in OCT technology and techniques, including wide-field OCT, adaptive optics OCT, polarization sensitive OCT, and more, offer closer monitoring of chorioretinal diseases, robust analysis in research, and insights into surgical management. These innovations also hold promise for advancing our understanding of the pathophysiology of chorioretinal diseases.

Summary: This study found that the enlargement rate of macular hole (MH) in patients during the one-month preoperative period is influenced by the stage of MH and the initial diameter of the hole. Patients with Stage 2 MH, especially those with a smaller hole diameter, should be considered for early surgical treatment.

Summary: This study examines the rates and trends of faculty promotions within the field of ophthalmology, with a focus on the rates of promotion among underrepresented in medicine (URiM) faculty. The results show that Black faculty had lower promotion rates and were more likely to leave academic medicine, highlighting the need for strategies and policies to address equity in promotion rates and retention of URiM faculty in academic ophthalmology.

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 study investigated the phenotype, variability, and penetrance of IMPG2-related maculopathy. The results showed that mono-allelic IMPG2 variants could result in haploinsufficiency manifesting as a maculopathy with variable penetrance and expressivity. Family members of patients with IMPG2-related retinitis pigmentosa may also present with vitelliform lesions. The maculopathy is usually limited to the fovea and is associated with moderate visual impairment.

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 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.
