ResultsBaseline characteristics including age, sex, preoperative IOP and medication use were comparable ...

Age related macular degeneration is known to be one of the major causes of irreversible blindness among the older generation. We present a mathematical model of partial differential equations for the therapy of this disease, which is based on the intravitreal injection of a drug into the vitreous body. For the treatment to work, the drug has to travel past the inner-limiting membrane into the retina and reduce the free vascular endothelial growth factor (VEGF) concentration by binding to at leas...

MethodsWe conducted a diagnostic concordance study of 150 eyes with microbial keratitis at a tertiary eye hospital in India. Two masked graders independently evaluated ASOCT scans for perforation, with disagreements resolved by consensus. We calculate...

PurposeTo investigate whether the geometric shape of the globe, sagittal length (SL) and Posterior Radius of curvature (rPC), differ between patients with rhegmatogenous retinal detachment (RD) and macular hole (MH), and to determine if these parameters offer better diagnostic differentiation than axial length (AL) alone. MethodsThis retrospective study included 20 MH and 20 RD patients. Groups were axial-length matched. Ocular biometry was performed with ultrasound to measure AL and SL. The PR...

PurposeTo evaluate the efficacy and safety of Gene III L-ergothioneine (EGT) Eye Care Solution for alleviating ocular discomfort in patients with dry eye syndrome (DES). MethodsIn this single-center, randomized, open-label, self-controlled trial, 40 DES patients were randomly assigned in a 1:1 ratio to one of two treatment groups: Group 1 received the Gene III EGT Eye Care Wash Solution via an eye wash cup (5 mL/vial), and Group 2 received the same formulation as Gene III EGT Eye Care Drops Sol...

There are many alternative methods to joystick control for control of Electric Powered Wheelchairs for users with neuromuscular disabilities, such as muscular dystrophy, and spinal cord injuries, such as tetraplegia. However, these methods- which include the sip-and-puff method, head and neck movement, blinking, or tongue movement- hinder social interaction, and are therefore detrimental to user independence. In recent years, research has explored the use of Electromyography (EMG) signals from a...

PurposeTo investigate the epidemiology of post-injection endophthalmitis (PIE) and evaluate the association of sociodemographic and clinical factors with incidence, timing of onset, and presenting visual acuity (VA) using the IRIS(R) Registry (Intelligent Research in Sight). DesignRetrospective cohort study. ParticipantsPatients with endophthalmitis after an intravitreal anti-VEGF injection in the IRIS(R) Registry from 2016-2023. MethodsOnly the first anti-VEGF injection per eye was included....

PurposeTimely detection of disease activity in chronic retinal diseases improves visual outcomes but is limited by the lack of validated systems for continuous monitoring and care management. We evaluated the real-world performance of an integrated remote physiologic monitoring and principal care management program (RemoniHealth(R)) using a self-administered multimodal retinal function test (Macustat(R)) for home monitoring. MethodsThis single-arm real-world intervention study was conducted acr...

IntroductionThe adoption of biologic therapies imposes a substantial financial burden on the Jordanian healthcare system. Ranibizumab is prescribed for various retinal disorders, and its associated costs are considerable. The introduction of biosimilars is beneficial in retaining desired clinical parameters while providing cost relief and enhanced access to patients. ObjectiveTo examine the budget impact and expanded access of switching to ranibizumabs biosimilar for the management of retinal d...

BackgroundThe sodium-restricted rice diet (RD) was once the only effective treatment for malignant hypertension (MH); however, a modern, comprehensive data analysis is lacking. We determined patient survival and ocular improvements in 544 MH patients treated between 1942-1982. MethodsAt entry, systolic blood pressure (SBP) was [≥]170 mmHg and retinal hemorrhage (n = 312), hemorrhage with papilledema (n= 211) or papilledema alone (n = 21) were present. Dates of death were available for 454 pa...

PurposeMuller cell (MC) morphology and markers were investigated using histology and immunohistochemistry in an eye with clinically documented multifocal geographic atrophy (GA) and correlated with clinical images. MethodsThe donor was followed clinically for five years and last examined six years before death. The superior posterior pole retina was dissected and immunolabeled with antibodies against glial fibrillary acidic protein (GFAP; activated MCs and astrocytes) and glutamine synthetase (...

BackgroundDespite recommendations in clinical guidelines, clinical experience indicates that engagement with splints and orthotics varies amongst people after stroke. ObjectivesThe aim of the study was to understand the factors that influence engagement with splints and orthotics in people after stroke. MethodsPeople after stroke who had been wearing a splint or orthotic (also known as devices) for at least 2 months under the care of one Community Neurosciences Team in the UKs National Health ...

IntroductionAnti-vascular endothelial growth factor (anti-VEGF) therapies are standards of care for vision-threatening retinal diseases. This retrospective observational study describes demographics, utilization, best recorded visual acuity (BRVA), and safety among eyes with neovascular age-related macular degeneration (nAMD), diabetic retinopathy (DR), diabetic macular edema (DME), or retinal vein occlusion (RVO) treated with the biosimilar aflibercept-ayyh (PAVBLU(R)) in routine clinical pract...

Centre of mass (COM) is a key measurement used to assess balance and mobility. Marker-based motion capture systems have traditionally been used to measure COM, but they are time-consuming and prone to marker error. Markerless motion capture systems offer a potential alternative, reducing setup time while maintaining accuracy. The ease of collecting markerless data may be particularly beneficial when study participants have limited mobility, such as those with stroke. This study aimed to determin...

PurposeAqueous humor drains fluid from the eye not only via the conventional pathway through the trabecular meshwork and Schlemms canal, but also within the eye is known to occur via pathways through the posterior chamber and optic nerve to the cerebrospinal fluid (CSF) surrounding the optic nerve. The mechanism is poorly understood, and non-invasive method for evaluation in living humans has not been established. We previously showed that eye drops containing O-17-labeled water (H217O) distribu...

AimTo assess the relationship between pointwise visual field (VF) sensitivity fluctuation and localised glaucoma progression. MethodsRetrospective observational analysis of prospective cohort data from 399 participants (641 eyes) in the African Descent and Glaucoma Evaluation Study (ADAGES). Glaucoma, glaucoma suspect, and control participants underwent annual examinations including VF testing. VF fluctuation was evaluated using the pointwise standard deviation (SD) of total deviation (TD) resi...

Frequent blood testing is a routine but burdensome reality for many children, particularly those with chronic, rare, or medically complex conditions. Repeated clinic, hospital, and laboratory visits can disrupt family life, increase stress for children and caregivers, and limit access to timely monitoring and research participation. Despite advances in pediatric care, blood collection has remained largely tethered to in-person clinical settings. This study validates a new model: safe, effective,...

Colour vision deficiency (CVD) affects up to 8% of males and 0.5% of females and currently lacks effective treatments. Individuals with CVD require visually accessible environments to flourish, the absence of which can cause unacceptable disparities in academic achievement and career progression. For current and aspiring clinician-scientists with CVD, inaccessible colour figures in scientific publications can hinder understanding of key information and potentially cause patient harm. Therefore, ...

Emergency department (ED) triage decisions critically impact patient care and are standardized, yet ethnoracial disparities in triage assignment are well documented. We analyzed ethnoracial differences in triage assignments across four U.S. EDs (two adult, two pediatric), comprising 1.4 million encounters from 2011-2025. To better characterize these disparities, we developed an automated triage algorithm that replicates the Emergency Severity Index (ESI) criteria, the standard triage protocol us...
