Imaging of adult ocular and orbital pathology - a pictorial review [PDF]

open access: yes, 2014
Orbital pathology often presents a diagnostic challenge to the reporting radiologist. The aetiology is protean, and clinical input is therefore often necessary to narrow the differential diagnosis.

Volumetric Measurement of Peripapillary Hyperreflective Ovoid Masslike Structures in Patients with Optic Disc Drusen

open access: yesOphthalmology Science, 2022
Purpose: To develop a method to determine the volume of peripapillary hyperreflective ovoid masslike structures (PHOMS) and to examine the correlation between PHOMS and anatomic optic nerve head characteristics in a large cohort of patients with optic ...

Differential monocular vs. binocular pupil responses from melanopsin-based photoreception in patients with anterior ischemic optic neuropathy. [PDF]

open access: yes, 2015
We examined the effect of anterior ischemic optic neuropathy (AION) on the activity of intrinsically photosensitive retinal ganglion cells (ipRGCs) using the pupil as proxy.

Optical coherence tomography demonstrating macular retinal nerve fiber thinning in advanced optic disc drusen

open access: yesOman Journal of Ophthalmology, 2014
Optic disc drusen (ODD) are extracellular proteinaceous excrescences in the optic nerve head. They enlarge over time and can cause damage to nerve fibers with resulting loss of visual field.

Characterization of retinal pigment epithelium layer in healthy and diseased retinas with high‐resolution adaptive optics transscleral flood illumination imaging

open access: yesActa Ophthalmologica, Volume 104, Issue 3, Page e277-e291, May 2026.
Abstract Purpose The retinal pigment epithelium (RPE) is critical in the pathophysiology of retinal diseases, such as age‐related macular degeneration. Adaptive optics transscleral flood illumination (AO‐TFI) offers rapid, detailed morphometric characterization of the RPE layer.

Evaluation of retinal nerve fiber layer thickness in a patient with bilateral optic disc drusen

open access: yesRevista Brasileira de Oftalmologia, 2015
Optic disc drusen (ODD) is the accumulations of calcified hyaline-like material within the substance of the optic nerve head. Optic disc drusen, especially if it is bilateral, may mimic the clinical presentation of papilledema.
