Relationship between intraocular pressure and optic nerve damage in optic nerve drusen
The authors present a retrospective study exploring the relationship between intraocular pressure (IOP) and optic nerve damage in patients with optic nerve drusen. The aim was to evaluate if patients with normal ocular pressure at the time of optic nerve...
Use of RAPDx device with optic nerve disease
The authors have previously reported on use of the RAPDx device for evaluating relative afferent pupillary defects (RAPD). RAPDx objectively determines the magnitude of RAPD by presenting light stimuli alternately to pairs of eyes with laterality. The parameters of amplitude...
Gender and ethnicity related differences in optic nerve head
The authors investigated the effect of ethnicity and gender on optic nerve head morphology comparing Indian and Caucasian males and females. The optic nerve head was investigated using spectral-domain optic coherence tomography (SD-OCT). Results showed that disc and rim areas...
Using a tumour registry to investigate optic nerve gliomas
This study is a retrospective comparative analysis. Patients with optic nerve glioma and pilocytic astrocytoma were identified through the Surveillance, Epidemiology and End Results (SEER) cancer registry covering a 42-year period using standardised codes. The following data was extracted: basic...
Retinoblastoma mortality associations with choroidal and optic nerve invasion
The authors present a retrospective cohort study. Data was extracted from the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) database, based in the US and founded in 1973. Cases of retinoblastoma were extracted using the inclusion criteria of...
Ground control to optic nerve – the space oddity to be studied
The authors explore the clinical entity that is known as Spaceflight Associated Neuro-ocular Syndrome (SANS). Its clinical characteristics include optic disc oedema, hyperopic refractive shifts, globe flattening, and chorioretinal folds, may pose a health risk for future space exploration. Understanding...
Understanding optic nerve head pericytes and glaucoma
The authors provide a comprehensive review of the current understanding of pericytes in the optic nerve head (ONH). Key points include: (1) Pericytes are contractile mural cells that play crucial roles in regulating blood flow, maintaining the blood-brain / blood-retinal...Optic nerve swelling – your survival guide (part 2)
In this second article we will discuss bilateral optic nerve swelling, its aetiology, various investigations and possible treatments. We will also discuss various protocols used in the management of suspected optic nerve swelling cases. (Part one of this topic available...
Use of the RAPDx device to evaluate efficacy of treatment in patients with optic nerve disease
The RAPDx objectively determines the RAPD magnitude by alternately presenting light stimuli to each eye and deriving amplitude and latency scores. The authors of this paper evaluated the amplitude and latency scores from the RAPDx together with other ophthalmic investigations...
Differences in elastometry of cornea and optic nerve head in both eyes of patients with NAION
Non-arteritic anterior ischaemic optic neuropathy (NAION) is an important cause of visual loss in the middle aged and elderly population. This prospective cross-sectional study investigates the biomechanical properties of optic nerve head (ONH) and cornea in both eyes of patients...
Natural history of optic nerve head drusen in a paediatric population
A retrospective case notes review is presented focusing on children diagnosed with optic nerve head drusen over an eight-year period. Inclusion criteria included cases coded for optic nerve head drusen and / or pseudopapilledema. The aim of the study was...
