Macular thickness and visual fields

1 April 2014 | | Glaucoma
The authors describe a comparison of spectral domain OCT with Humphrey visual fields (HVF) mean deviation (MD) and pattern standard deviation (PSD), examining the retinal thickness of the macula and circumpapillary retinal nerve fibre layer (RNFL) defects. Seventy-three subjects who...

Combined anti-VEGF and PDT for wet AMD

1 February 2014 | | Retina / Uvea / Vitreous
The authors report on a retrospective case series of combined anti-VEGF and photodynamic therapy (PDT) in the treatment of wet age-related macular degeneration (AMD) refractory to anti-VEGF monotherapy alone. The criteria for treatment failure of anti-VEGF monotherapy were persistent subretinal...

Disc margin delineation using spectral domain OCT

1 December 2013 | | Glaucoma
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....

The science of glaucoma management: highlights of the 2020 Moorfields International Glaucoma Symposium

5 October 2020 | | Ophthalmology, Glaucoma
Held earlier this year, the 12th annual Moorfields International Glaucoma Symposium provided a forum for advanced clinical and scientific exchange in glaucoma management. The authors describe the key presentation themes and debates, highlighting specific topics of interest to glaucoma specialists....

History A 65-year-old lady presented with a ten year history of nonspecific visual disturbance and mild symptoms of dry eyes. Questioning revealed progressive nyctalopia. Previous medical history of note included Crohn’s disease requiring two bowel resections including small intestine. Figure...

Possible COVID-19 related maculopathy

5 April 2022 | | Ophthalmology, Imaging, Retina / Uvea / Vitreous, COVID-19
COVID-19 is being investigated as a potential cause for various ocular diseases, with growing evidence of related retinal vascular changes, that vary from isolated cotton wool spots and retinal haemorrhages to retinal vascular occlusions [1.2]. COVID-related macular affection has also...

Hydroxychloroquine toxicity

1 August 2017 | Ophthalmology, Retina / Uvea / Vitreous
Being the subject of litigation is stressful and upsetting. Having to look back over your previous decisions and justify the care you delivered in good faith can be difficult. Sadly, we all live with the Sword of Damocles above us...

Retinal sequelae of high voltage electric current injury

5 June 2023 | | Retina / Uvea / Vitreous
Introduction High-voltage electrical currents may result in significant ocular complications, ranging from mild cataracts to vision-threatening retinal and optic nerve problems [1]. The severity of damage depends on various factors, including intensity and type of current, duration of exposure, entry...

Headaches in ophthalmology (part 2)

1 December 2018 | | Ophthalmology, Neuro-Ophthalmology
Ophthalmologists see a large number of patients with headaches or facial pain in the ophthalmic outpatient clinics or in emergency clinics. Over two articles, I will discuss several causes of headaches, ocular manifestations and proposed management and referral options. It...

Idiopathic intracranial hypertension (IIH)

3 June 2021 | | Ophthalmology, Neuro-Ophthalmology, Emergency Ophthalmology
IIH is a medical condition where the intracranial pressure (ICP) is raised without an obvious cause. The cerebrospinal fluid (CSF) is produced in by the choroid plexus in the lateral ventricles and the roof of the third and fourth ventricles,...

Adaptive optics imaging: resolving single cells in the living eye

1 June 2014 | | Cornea / External Eye Disease
The human retina is unique in the central nervous system (CNS) in that it can be directly visualised non-invasively. Technological advances of several imaging modalities, including optical coherence tomography (OCT), multichannel scanning laser ophthalmoscopy (SLO) and fundus photography, have afforded...

Diabetic Macular Oedema

1 December 2013 |
Diabetes mellitus is a metabolic disorder that affects the metabolism of all three categories of carbohydrates, lipids and proteins. This condition is characterised by chronic hyperglycaemia [1]. This can cause end organ damage. The estimated worldwide diabetes prevalence for 2010...
