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....

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...

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...

Nonarteritic anterior ischaemic optic neuropathy

This review article describes nonarteritic anterior ischaemic optic neuropathy (NAION). This condition is one of the common causes of visual loss in adults. The article uses a good range of references and is divided under the headings of; demographics, clinical...

Choroidal and macular thickness in nonarteritic anterior ischaemic optic neuropathy

This study evaluates the choroidal and macular thickness in patients with chronic nonarteritic anterior ischaemic optic neuropathy (NA-AION). Two groups of subjects were compared, group one included 20 eyes with chronic NA-AION and group two, 31 healthy control eyes. The...

Inflammation and microvascular changes in diabetic retinopathy

Studies have shown that neurodegeneration and inflammation in the retina start early in diabetic retinopathy (DR) and can be present before the latter is clinically evident. The aim of this retrospective review of 99 diabetic patients was to evaluate retinal...

OCT angiography in PAMM secondary to CRVO

Paracentral acute middle maculopathy (PAMM) is a recently described manifestation presenting with hyperreflective bands within mid retina on spectral domain optical coherence tomography (SD OCT). The current view is that these findings are markers of ischaemia of deep retinal circulation....

It’s not always GCA

Giant cell arteritis (GCA) is an immune mediated granulomatous inflammatory disease that affects muscular middle or large sized arteries. It is considered as a continuation of polymyalgia rheumatica (PMR) when the severity of the disease has increased. It is the...

A near miss

A 55-year-old gentleman presented with a ‘blurry patch’ to his left eye which he had noticed for the past two months. The visual acuity with correction was 6/5 in the right eye and 6/6 in the left eye on the...

Predicting ischemic lesion location using perimetry

The authors present a retrospective records review, using the search terms homonymous hemianopia, visual field loss and MRI. Only posterior circulation artery territory ischemic strokes were included. Demographics, stroke details and initial and follow-up with 24-2 SITA Standard perimetry results...

Non-arteritic anterior ischaemic optic neuropathy in the Asian population

This article provides an evaluation of changes in visual function associated with non-arteritic anterior ischaemic optic neuropathy (NAION) among Korean patients. Visual changes were identified as a reduction in visual acuity by three Snellen lines or a deterioration of visual...

Review of non-arteritic anterior ischaemic optic neuropathy

This article reviews the risk factors, clinical presentation and therapies that have been investigated for non-arteritic anterior ischaemic optic neuropathy (NAAION). Additionally, it provides an update from recent rodent and primate models, offering a new insight into the pathophysiology of...
