Purpose: Optic nerve avulsion (ONA) is a rare but serious presentation of ocular trauma. This study investigates the presenting characteristics and etiologies of all cases of ONA over an 8-year-period at a tertiary eye care center in the Middle East.Methods: The medical records of patients diagnosed with ONA at an Ophthalmic Emergency Department between November 2014 and November 2022 were analyzed in this retrospective cohort study. Data were collected on patient age, sex, affected eye, cause of injury and imaging studies. The best-corrected visual acuity (BCVA) at presentation and at the last follow-up visit, and the duration of follow-up were documented.Results: The study sample was comprised of 44 eyes of 43 patients with ONA with median age of 16.5 (9.3– 26.8) years ranging from 2 years old to 70 years old. There were (35;79.5%) males and (9; 20.5%) females. Most cases presented with an affected left eye (27; 61.4%) followed by the right eye (16; 36.4%) and only one patient (2.3%) had bilateral ONA. The most common cause of trauma resulting in ONA was a metallic object (8;18.2%). This study demonstrates the value of multi-sequence Magnetic resonance imaging (MRI) in the setting of unexplained vision loss when other modalities are inadequate or inconclusive.Conclusion: Ophthalmic morbidity resulting from ONA can be devastating. Metallic object injuries were the most prevalent cause of ONA. The presence of associated media opacities challenges the initial diagnosis of ONA. In the vast majority of cases, the vision ended as no light perception (NLP), indicating permanent vision impairment. [ABSTRACT FROM AUTHOR]

Purpose: Clinical research brings the potential of improved diagnostics, sight-saving treatments, and more accessible services to those suffering with severe sight impairment (SSI). This report investigates whether registered ophthalmology clinical studies address the leading causes of SSI in the general and working populations of the United Kingdom (UK).Methods: The latest statistics on the leading causes of SSI in the UK general and working populations were identified by searching PubMed, Cochrane Library, and TRIP databases. Clinical study registries were searched to identify registered clinical studies (on or prior to 1st December 2022) on the leading causes of SSI. The relationship between the number of clinical studies on leading causes of SSI and the percentage of SSI certifications they account for was analyzed.Results: In the UK general population, the number of registered clinical studies on the leading causes of SSI is statistically significantly correlated (Spearman's rho = 0.86, p < 0.01) with the percentage of SSI certifications they account for. However, there is no correlation between the two in the UK working population (aged 16– 64) (Spearman's rho = 0.15, p = 0.70). Eye conditions accounting for the most SSI certifications in individuals of working age have significantly less clinical research activity than those that cause the most SSI certifications in the general population. Out of the leading causes of SSI certifications studied, disorders of the visual cortex and congenital anomalies of the eye have the least clinical research activity.Conclusion: Clinical research into the leading causes of SSI in the general population is essential. However, it is important to consider eye conditions that cause the most severe visual impairment in individuals of working age due to the significant health and socioeconomic implications of sight loss in this population.

Purpose: The purpose of this study was to understand individual-, social-, and system-level factors that affect compliance with recommended diabetic retinopathy (DR)-evaluations, and how these factors vary between English and Spanish speakers. Patients and Methods: We conducted a qualitative study using semi-structured interviews. Study subjects included Kaiser Permanente Southern California members with type II diabetes mellitus at least aged 26 years who spoke English or Spanish. Patients were divided into groups based on their adherence with DR evaluations. Our main outcome measure was the major themes expressed by patients that explained their compliance with DR evaluation. Results: Fifty-one participants were enrolled: 30 English speakers (11 nonadherent, 19 adherent) and 21 Spanish speakers (8 nonadherent, 13 adherent). Adherent patients were more likely to have had experience with diabetes and identify as being responsible for their own care. Substantially more non-adherent patients suggested that beliefs and attitudes were the reasons people missed retinopathy appointments. More English-speaking participants tended to be self-directed in managing their healthcare, whereas more Spanish speakers relied on others for help. English speakers also noted better relationships with their physicians. Spanish speakers outlined problems with insurance coverage and costs as barriers. Conclusion: These data suggest two specific intervention strategies that eye care providers could implement to improve adherence with diabetic retinopathy screening and follow up: incorporating a person with DR-related visual loss into the team of staff delivering diabetes support programs and communication campaigns including specific messaging to address fears related to vision loss.
