Herpes zoster, Intraocular pressure, Ischemic optic neuropathy, 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....

Optic nerve, idiopathic intracranial hypertension, papilloedema
The authors review the latest evidence regarding how the optic nerves are affected by idiopathic intracranial hypertension (IIH), possible pathophysiology and methods of assessment. IIH is described as a clinical syndrome of raised intracranial pressure of unknown aetiology. A systematic...

Optic nerve head drusen, intraocular pressure, retinal nerve fibre layer, visual field
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...

Anterior ischaemic optic neuropathy, inflammation, monocyte to high-density lipoprotein ratio
The authors evaluate the monocyte to high-density lipoprotein (HDL) ratio (MHR) in patients with arteritic and non arteritic anterior ischaemic optic neuropathy (A-AION / NA-AION). A distinction between the two types of AION is essential to begin appropriate treatment, which...

EYE - Neuro-ophthalmology
This prospective clinical study compared retinal and peripapillary blood flow parameters in migraine patients during an attack with healthy controls using optical coherence tomography angiography (OCTA). OCTAs were performed on 52 eyes from 26 migraine sufferers and 48 eyes from...
Quality of life after oculoplastic surgery
This is a literature review of published quality of life surveys in patients who have undergone a variety of oculoplastic procedures. The authors emphasise the importance of patient reported outcomes, noting that clinician and patient perceptions may differ, and that...
Topical steroids and ptosis surgery
This is a retrospective review examining the effect of prior topical steroid use on patients undergoing ptosis surgery. Out of a total of 406 eyelids undergoing ptosis repairs, 44 had received topical steroids for an average of 3.7 years prior...
Early refractive correction promotes esotropia control
This study sought to determine the incidence and characteristics of esotropia in a Northern Ireland population of children <7 years old in a one-year period. The authors report a 2013 cohort in which the area catchment had 29,365 children under...
Measurement considerations in OCT results with suspected glaucoma
The purpose of this study was to determine retinal nerve fibre (RNFL) thickness parameters and assess the relationship between the cup-to-disc (CD) ratio and RNFL measurements of paediatric patients who had optic nerve appearance suspicious for glaucoma based on enlarged...
Prevalence of visual function impairment in congenital ptosis
This study sought to evaluate the prevalence of visual function loss in the setting of congenital ptosis. This was a retrospective study of 155 eyes of 134 patients; 72 males and 62 females. Mean age at diagnosis was 7.8 ±5.8...
Prism adaptation vs. augmented surgery for esotropia
Prism adaptation and the augmented surgery formula are different tools of surgical augmentation. The purpose of this study was to compare these two methods in the management of acquired concomitant esotropia. This was a prospective study of 40 patients with...
