Variability between handheld fundus cameras

3 January 2025 | | EYE - Glaucoma
Handheld fundus cameras offer the potential of enhancing opportunities for telemedicine diagnosis of glaucoma, especially in underserved settings, as they are less bulky, inexpensive and don’t require skilled personnel compared to traditional table-mounted retinal cameras. This study aimed to compare...

Refraction planning in cataract: avoid creating an unhappy patient

1 June 2017 | | EYE - Cataract, EYE - Refractive
“It is much more important to know what sort of a patient has a disease than what sort of a disease a patient has.” William Osler The focus of this paper is the prevention of an unhappy patient following cataract...

Effect of oxygen levels on binocular summation of dark vision

1 December 2014 | | EYE - Neuro-ophthalmology | Binocular summation, dark adaptation, monocular vision, neural summation, probability summation
Previous studies have reported conflicting results on the existence of binocular enhancement of dark vision. This study compares monocular and binocular absolute thresholds of dark adaptation in two different populations (healthy individuals and those with chronic respiratory insufficiency). The study...

Enzymatic clearance of anterior chamber infiltrate in uveitis

1 February 2014 | | EYE - Vitreo-Retinal
Aqueous humour (AH) which fills the anterior chamber (AC) of the eye provides nutrients to the cornea and the lens. Clearance of cellular and particular matter from AH is necessary for good visual acuity. In part this is achieved by...

How are pigment dispersion syndrome and pigmentary glaucoma inherited?

1 August 2019 | | EYE - Glaucoma
This single centre prospective, cross-sectional study assessed the relatives of patients with pigment dispersion syndrome (PDS) and pigmentary glaucoma (PG) to determine the heritability of these conditions over an 11 month period. One hundred and one unrelated patients with PDS...

A pulsatile pump in the TM, a new concept in trabecular outflow research

1 October 2021 | | EYE - Glaucoma | Aqueous outflow pump, Elastance, Glaucoma, Intraocular pressure regulation, Pulsatile aqueous outflow, Schlemm's canal valves
This is a research article where the authors propose a new model in conceptualising the mechanisms involved in the aqueous outflow at the trabecular meshwork (TM). The authors demonstrated evidence of a pump within the Schlemm’s canal. A pulse generated...

Optical coherence tomography – reinventing the eye examination

1 October 2016 | | EYE - Vitreo-Retinal, EYE - Imaging
It has been 25 years since Huang et al. presented the first optical coherence tomography (OCT) images in Science [1]. With vast improvements in OCT technology over the years, it is now possible to acquire high-resolution cross-sectional images of the...

The interpretation and use of ultrasound biomicroscopy (part 1)

1 October 2016 | | EYE - Cornea, EYE - Imaging, EYE - Vitreo-Retinal
Ultrasound Biomicroscopy (UBM) has become increasingly important for the diagnosis of a variety of anterior segment pathologies. Most ophthalmologists are familiar with conventional B-scan ultrasonography techniques, which operate at lower sound frequencies (7.5 to 20MHz). UBM is an ultrasound technique...

Glaucoma-NET: a novel way of improving glaucoma management in sub-Saharan Africa

1 June 2022 | | EYE - Cornea, EYE - General
Background Glaucoma is the second most common cause of blindness worldwide [1]. People with untreated glaucoma suffer from irreversible, progressive loss of sight. The disease is characterised by progressive loss of visual field, with pathological cupping of the optic disc...

Understanding vasoproliferative retinal tumours

4 February 2021 | | EYE - Vitreo-Retinal, EYE - General
Syed Irtiza Ali Shah explores this rare and unusual condition through a fascinating case presentation. Vasoproliferative tumours of the retina (VPTR) are a vascular mass with an associated exudative retinopathy alongside the presence of minimally dilated feeder vessels. This is...

The structure function relationship in glaucoma

1 April 2017 | | EYE - Glaucoma
Chronic open angle glaucoma (COAG) is the second most common cause of blindness worldwide. It is diagnosed on the basis of three clinical signs, raised intraocular pressure (IOP), visual field (VF) defects and structural changes to the optic nerve head...

Congenital and paediatric cataract: Advances in diagnosis and management

4 December 2025 | | EYE - Paediatrics, EYE - Cataract
Congenital and paediatric cataracts are relatively rare, although prevalence varies significantly between countries, influenced by factors such as nutrition, immunisation policy and population genetics [1]. In the UK, around 3–4 of every 10,000 babies are born with cataracts. It’s a...
