Orbital sphenoid sinus trauma: a rare trauma case

With a high complication and mortality rate, intra-sphenoidal and transorbital trauma poses a high complication rate and remains challenging to manage. Numerous key structures run nearby such as: the optic nerve, internal carotid arteries and ophthalmic arteries. The authors present...

Herpes zoster ophthalmicus: the essentials

Herpes zoster, also referred to as shingles, is a common infection most typically caused by the reactivation of varicella zoster virus that lies dormant (sometime for decades) in the dorsal root nerve ganglion following primary chickenpox infection [1]. In 10-20%...

Covid-19 ophthalmopathy

Ocular involvement is not uncommon in patients with Covid-19. However, the incidence of Covid-19 ophthalmopathy is unclear. The authors present a prospective case series including 2445 consecutive cases presenting at a neuro-ophthalmology clinic during the last resurgence of SARS-CoV-2 infection....

Four key questions and answers for glaucoma practitioners

In this discussion paper the authors pose four questions for the clinician diagnosing and monitoring glaucoma, and supply evidence-based answers. Worldwide, the most common functional test used to diagnose and monitor glaucoma is static automated perimetry, most typically with a...

Paediatric optic disc anomalies

Anomalies of the optic nerve are relatively rare, but account for a significant proportion of sight impairment in children and adults. The recognition of these anomalies by eye health professionals is important not only due to their potential impact on...

Emerging developments in dry eye

An estimated 344 million people worldwide suffer from dry eye [1]. This chronic syndrome is characterised by a vicious cycle of tear film hyperosmolarity, tear instability and corneal stress, leading to increased friction, inflammation, ocular surface damage and decreased visual...

Providing primary eyecare services during a global pandemic: the new normal

It would be fair to say that 2020 hasn’t quite turned out to be the year that anyone predicted. Living with a global pandemic has become our reality and we are having to get used to many aspects of our...

Ophthalmology Lecture Notes (Twelfth Edition)

During medical school, our seniors often told us that the easiest way to remember something is to understand it. And rightly so, when I came across the Ophthalmology Lecture Notes textbook as a student I realised that the key to...

A novel test for unilateral functional visual loss

The authors report results of three cases of functional visual loss, where regular ophthalmic testing was not sufficient to confirm the diagnosis. In these cases, bilateral concurrent eye examination was performed using a head-mounted perimeter (imo), to facilitate the diagnosis....

Risk factors for NTG in a young Korean population

Previously known ocular and systemic risk factors for normal tension glaucoma (NTG) include myopia, peripapillary atrophy, disc haemorrhage, migraine, obstructive sleep apnoea, thyroid disease and cerebral infarction. However, most NTG risk factor studies have examined patients aged 40 years and...

Stroke-vision symptoms

The purpose of this study was to investigate the frequency and type of visual symptoms following stroke and evaluate what certain factors were associated with the absence of visual symptoms. This was a prospective, multi-centre, observation cohort study with 915...

Disc margin delineation using spectral domain OCT

Observing progressive anatomical changes of the optic nerve head is essential in the detection of progression in glaucoma. Imaging devices continue to evolve and are useful in detecting change in established glaucoma, although probably less useful in an initial diagnosis....
