Addressing Technical Failures in a Diabetic Retinopathy Screening Program.

Purpose: Diabetic retinopathy (DR) is a preventable cause of blindness detectable through screening using retinal digital photography. The Irish National Diabetic Retina Screening (DRS) programme, Diabetic RetinaScreen, provides free screening services to patients with diabetes from aged 12 years and older. A technical failure (TF) occurs when digital retinal imaging is ungradable, resulting in delays in the diagnosis and treatment of sight-threatening disease.

The Role of the Ophthalmic Genetics Multidisciplinary Team in the Management of Inherited Retinal Degenerations-A Case-Based Review.

(1) Background: Inherited retinal degenertions are rare conditions which may have a dramatic impact on the daily life of those affected and how they interact with their environment. Coordination of clinical services via an ophthalmic genetics multidisciplinary team (OG-MDT) allows better efficiency of time and resources to reach diagnoses and facilitate patient needs. (2) Methods: This clinical case series was conducted by a retrospective review of patient records for patients enrolled in the Target 5000 programme and managed by the OG-MDT, at the Mater Hospital Dublin, Ireland ( = 865) (3) Results: Herein we describe clinical cases and how the use of the OG-MDT optimizes care for isolated and syndromic IRD pedigrees.

Additional measures of macular function beyond visual acuity.

Purpose: Visual function is a complex process in which external visual stimuli are interpreted. Patients with retinal diseases and prolonged follow-up times may experience changes in their visual function that are not detected by the standard visual acuity measure, as they are a result of other alterations in visual function. With the advancement of different methods to evaluate visual function, additional measurements have become available, and further standardization suggests that some methods may be promising for use in clinical trials or routine clinical practice.

Evaluating transformative health leadership education for Indigenous health: a mixed methods study.

Background: There is an urgent need to improve structural competency and anti-racism education across health systems. Many leaders in health systems have the ability and responsibility to play a significant role in policy change and transforming healthcare delivery to address health inequities and injustices. The aim of this project was to evaluate a new health leadership Indigenous health course: PLUS4I.

Adherence of patients with age-related macular degeneration to AREDS 2-recommended nutritional supplements.

Background: The Age-Related Eye Disease Study 2 (AREDS 2) proved the benefit of vitamin and mineral supplementation in preventing advanced age-related macular degeneration (AMD). AREDS 2 supplements are indicated for patients with either bilateral intermediate AMD (AREDS category 3) or unilateral neovascular AMD (AREDS category 4).

Aims: The aims of this telephone survey were to identify the rate of adherence of patients to AREDS 2 supplements and the factors associated with non-compliance in these patient groups.

The Effect on Patients' Visual Acuity and Grade, Secondary to Non-Attendance at Treatment Centers, Post Referral from Diabetic RetinaScreen Ireland.

Background: Patient non-attendance following referral to hospital is a significant challenge, in particular, for persons with diabetes.

Aim: We sought to determine the impact on both visual acuity and the subsequent follow-up retinopathy grade of patients when they fail to attend Diabetic Retinopathy Treatment (DRT) Centers following referral from Diabetic RetinaScreen (DRS).

Methods: A retrospective analysis of patients discharged from DRT due to multiple consecutive missed appointments between January 2016 and June 2021.

Intolerance of uncertainty, posttraumatic stress, depression, and fears for the future among displaced refugees.

Introduction: The vast majority of the 100 million forcibly displaced persons worldwide live in a state of prolonged uncertainty with limited resettlement prospects and access to resources. Little is known, however, regarding how refugees and asylum-seekers cope with this uncertainty.

Methods: In this study, we investigated the longitudinal association between a measure of how people cope with uncertainty (intolerance of uncertainty (IU)), fears for the future, posttraumatic stress disorder (PTSD) symptoms and depression symptoms.

The impact of COVID-19 stressors on refugee mental health and well-being in the context of sustained displacement.

Refugees and asylum seekers in contexts of sustained displacement represent particularly vulnerable communities during the COVID-19 pandemic. The aim of this study was to identify profiles of COVID-19 stressors in refugees in a transit context (i.e.

-Associated Retinopathy and Nanophthalmos in Two Irish Probands: A Case Report.

The conjunction of nanophthalmos (NO) and retinitis pigmentosa (RP) provides challenges to effective clinical management while narrowing the genetic spectrum for targeted molecular diagnostics. This case study describes two not knowingly related adult cases of -associated retinopathy and nanophthalmos (MARN). Structural features including short axial lengths (mean 16.

Subretinal fluid may protect against macular atrophy in neovascular age-related macular degeneration: 5 years of follow-up from Fight Retinal Blindness registry.

Purpose: The purpose of the study was to assess the association of macular atrophy (MA) according to the activity of macular neovascularization (MNV) (inactive, only subretinal fluid [SRFL], or active, i.e. including intraretinal fluid [IRFL]) using optical coherence tomography (OCT) in patients with neovascular age-related macular degeneration (nAMD).

Serum MicroRNAs Profiling in Age-Related Macular Degeneration.

Age-related macular degeneration (AMD) is a progressive, degenerative disease of the retina which ultimately results in the irreversible loss of central vision. AMD is one of the foremost causes of blindness in people over the age of 50. Although the precise pathogenesis of AMD has not yet been elucidated, AMD results from a complex interaction between genetic predisposition and environmental provoking factors.

Context, coping, and mental health in refugees living in protracted displacement.

There is currently an unprecedented number of forcibly displaced people worldwide. Little is known, however, about how external stressors and internal coping strategies intersect to influence mental health in displaced refugees, particularly whether specific types of coping strategies are more or less effective across different levels of external stress. This study aimed to understand whether positive and negative internal coping strategies were differentially associated with mental health across high and low levels of external stressors in displaced refugees.

Impact of displacement context on psychological distress in refugees resettled in Australia: a longitudinal population-based study.

Aims: Refugees typically spend years in a state of protracted displacement prior to permanent resettlement. Little is known about how various prior displacement contexts influence long-term mental health in resettled refugees. In this study, we aimed to determine whether having lived in refugee camps community settings prior to resettlement impacted the course of refugees' psychological distress over the 4 years following arrival in Australia.

Electrophysiology-Guided Genetic Characterisation Maximises Molecular Diagnosis in an Irish Paediatric Inherited Retinal Degeneration Population.

Inherited retinal degenerations (IRDs) account for over one third of the underlying causes of blindness in the paediatric population. Patients with IRDs often experience long delays prior to reaching a definitive diagnosis. Children attending a tertiary care paediatric ophthalmology department with phenotypic (i.

Usher syndrome type IV: clinically and molecularly confirmed by novel ARSG variants.

Usher syndrome (USH) is an autosomal recessively inherited disease characterized by sensorineural hearing loss (SNHL) and retinitis pigmentosa (RP) with or without vestibular dysfunction. It is highly heterogeneous both clinically and genetically. Recently, variants in the arylsulfatase G (ARSG) gene have been reported to underlie USH type IV.

Clinical and Genetic Re-Evaluation of Inherited Retinal Degeneration Pedigrees following Initial Negative Findings on Panel-Based Next Generation Sequencing.

Although rare, inherited retinal degenerations (IRDs) are the most common reason for blind registration in the working age population. They are highly genetically heterogeneous (>300 known genetic loci), and confirmation of a molecular diagnosis is a prerequisite for many therapeutic clinical trials and approved treatments. First-tier genetic testing of IRDs with panel-based next-generation sequencing (pNGS) has a diagnostic yield of ≈70-80%, leaving the remaining more challenging cases to be resolved by second-tier testing methods.

Differential Circulating MicroRNA Expression in Age-Related Macular Degeneration.

This study explored the expression of several miRNAs reported to be deregulated in age-related macular degeneration (AMD). Total RNA was isolated from sera from patients with dry AMD ( = 12), wet AMD ( = 14), and controls ( = 10). Forty-two previously investigated miRNAs were selected based on published data and their role in AMD pathogenesis, such as angiogenic and inflammatory effects, and were co-analysed using a miRCURY LNA miRNA SYBR Green PCR kit via quantitative real-time polymerase chain reaction (qRT-PCR) to validate their presence.
