Choroidal vascularity in NAION

The authors present a cross-sectional, non-interventional study of healthy volunteers and those with non-arteritic anterior ischaemic optic neuropathy (NAION) recruited over a six-month period at a single site. NAION is the most common cause of acute optic neuropathy over the...

G-CSF intravitreal injections for NAION: a pilot study

In rodent models with anterior ischemic optic neuropathy (AION), granulocyte colony-stimulating factor (G-CSF) confers a neuroprotective effect on retinal ganglion cells (RGCs) via anti-apoptotic and anti-inflammatory processes. This prospective study investigated the efficacy of intravitreal injection of G-CSF for the...

A retrospective medical notes review in patients with poor vision due to NAION

Very severe visual loss (hand movements or less) is typical of arteritic anterior ischaemic optic neuropathy (AION) and relatively rare in non-arteritic AION (NAION). This study aimed to report the frequency of very poor visual acuity (VA) in NAION. The...

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...

How common is optic disc drusen in young patients with NAION?

A retrospective notes review at two tertiary care centres was completed between 2009 and 2019. The inclusion criteria for the study was a diagnosis of nonarteritic anterior ischaemic optic neuropathy (NAION) in at least one eye, aged between 18 and...

Unique case of steroid-induced intraocular pressure spike causing NAION

The literature describes previous cases of nonarteritic anterior ischaemic optic neuropathy (NAION) following rapid rises in intraocular pressure (IOP) leading to reduced optic nerve head perfusion and disruption. This is commonly following ophthalmic procedures, acute glaucoma or steroid eye drops....

Investigation of blood platelet parameters in anterior ischaemic optic neuropathy

The aim of this clinical retrospective comparative study was to assess the possible relationship between arteritic anterior ischaemic optic neuropathy (AAION) and non-arteritic anterior ischaemic optic neuropathy (NAION) with blood platelet parameters and neutrophil-to-lymphocyte ratio (NLR). The medical records of...

A review of the risk of nonarteritic anterior ischaemic optic neuropathy post-cataract surgery

A systematic review and meta-analysis are presented with the aim of assessing whether cataract surgery increases the risk of non-arteritic anterior ischaemic optic neuropathy (NAION) and identify potential predictors of risk. The search strategy components are outlined in detail. A...

Do occult neuroretinitis and non-arteritic anterior ischaemic optic neuropathy differ in presentation?

This study evaluates differences between neuroretinitis and non-arteritic anterior ischaemic optic neuropathy (NAAION) in terms of patient demographics, clinical presentation, and optical coherence tomography (OCT) findings. Medical records of patients with a final diagnosis of occult neuroretinitis or NAAION were...
