Optic Nerve Head Measurements Across Optical Coherence Tomography Platforms and Incidental Optic Nerve Head Drusen in Community Screenings

open access: yesEye &ENT Research, EarlyView.
ABSTRACT Background Automated vertical cup‐to‐disc ratio (VCDR) measurements are commonly used in optic nerve assessment, but measurements may vary across optical coherence tomography (OCT) platforms, particularly in eyes with atypical optic nerve anatomy such as optic nerve head drusen (ONHD).

Regional growth kinetics of geographic atrophy in age‐related macular degeneration with and without fovea‐sparing

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Fovea‐sparing geographic atrophy (GA) patients retain near‐normal central vision. To better understand GA progression in relation to the fovea, we performed a semi‐automated image analysis of regional atrophy growth in a long‐term GA natural‐history cohort. Methods Prospective‐observational, single‐centre‐study (02/2013–07/2025) at the

Recognizing Signs of Abusive Head Trauma

open access: yesJournal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background Abusive head trauma (AHT) remains the leading cause of fatal traumatic brain injury in infants and young children. Diagnosis is frequently delayed or missed due to nonspecific clinical presentation and unreliable histories, making neuroimaging a critical component of the diagnostic process. Objective This review synthesises computed

Accessible digital ophthalmoscopy based on liquid-lens technology [PDF]

open access: yes, 2015
Ophthalmoscopes have yet to capitalise on novel low-cost miniature optomechatronics, which could disrupt ophthalmic monitoring in rural areas. This paper demonstrates a new design integrating modern components for ophthalmoscopy.
