Social determinants of health (SDH) play a crucial role in shaping health outcomes. Few studies have explored the impact of SDH in ocular oncology, looking at differences in disease presentation, treatment choices, and outcomes based on race, ethnicity, socioeconomic status (SES), and insurance status. Retinoblastoma exhibits disparities in survival, with lower-income countries experiencing substantially lower rates compared to high-income countries.

Purpose: Ultra-widefield (UWF) imaging is commonly used in ophthalmology in tandem with scleral depressed examinations (SDE) to evaluate peripheral retinal disease. Because of the increased reliance on this technology in tele-ophthalmology, it is critical to evaluate its efficacy for detecting the peripheral retina when performed in isolation. Therefore, we sought to evaluate UWF imaging sensitivity in detecting retinal horseshoe tears (HSTs).

Diffuse unilateral subacute neuroretinitis (DUSN) is a rare ocular infectious disease caused by migrating larvae of a nematode. DUSN is often a diagnostic challenge as it is difficult to identify the pathogenic nematode on funduscopic examination because it moves frequently and often resides within the subretinal space. Herein, the authors present a patient with unilateral, chronic visual loss who was noted to have a live, motile worm within the vitreous cavity.

Purpose: The hallmark of proliferative diabetic retinopathy (PDR) is retinal neovascularization. Tortuous intraretinal vascular segments known as intraretinal microvascular abnormalities (IRMAs) are a known risk factor for neovascularization (NV), but whether IRMA represents a biomarker or a vascular precursor lesion to NV has not been demonstrated. The purpose of this study was to determine whether IRMA may evolve directly into NV.

Article Synopsis
  • The study investigated antibiotic resistance patterns in Staphylococcus epidermidis isolates related to endophthalmitis, focusing on resistance genes and phenotypic resistance comparisons.
  • It analyzed 75 isolates from a retrospective case series, finding over 60% resistant to methicillin and erythromycin, with strong agreement between genetic and phenotypic resistance.
  • The results suggest that antibiotic resistance may involve multiple genes, some of which could be inactive, while none of the isolates showed resistance to vancomycin.
