Comparison of structural and functional features in primary angle closure and open-angle glaucoma

In this large cross-sectional study, differences in structural and functional damage were assessed among patients with primary open-angle glaucoma (POAG) and primary angle closure glaucoma (PACG) with optical coherence tomography and reliable visual field testing. Two-hundred and eighty-three patients with...

Tumour characteristics influencing visual field outcomes

This retrospective study aimed to explore correlations between pituitary tumour characteristics which influenced visual field changes. Cases of transsphenoidal surgery from a six-year period resulting in a pathologic diagnosis of pituitary adenoma from a single centre were identified. Individuals were...

Acromegaly associated with enlargement of extraocular recti muscles

This retrospective case review aimed to evaluate the frequency and extent of extraocular muscle enlargement in cases of acromegaly at presentation. All new presentations of acromegaly diagnosis at a single tertiary centre over a five-year period were screened for inclusion....

Corneal and astigmatic changes after medial rectus recession surgery of 6mm

This study prospectively compared changes in astigmatism before and two months after unilateral recession of medial rectus muscles using Pentacam. The fellow unoperated eye was used as the control eye. The study included 66 eyes and 33 patients; 21 males,...

Comparing retinal thickness in Parkinson’s disease, essential tremor and healthy controls

This study aimed to compare retinal findings in chronic essential tremor (ET), early Parkinson’s disease (PD) and healthy controls. Those recruited with ET had to have received a diagnosis a minimum of three years previous and those with PD had...

Early structural and functional retinal changes in intermittent exotropia

This study aimed to evaluate and compare spectral domain optical coherence tomography (SD OCT) and electrophysiological measures in patients with intermittent exotropia and healthy controls, to outline changes in retinal and optic nerve structure and function. This was a cross-sectional...

Changes, with increasing age of children, in optic nerve head parameters and retinal thickness

In this study, the authors aimed to compare stereometric parameters of the optic disc and inner retinal layer thickness (peripapillary retinal nerve fibre layer (pRNFL) and ganglion cell inner plexiform layer (GCIPL)) at two time points in the same children...

Findings in an orthoptic-led clinic for children with epilepsy

This retrospective study aimed to determine the prevalence of ophthalmic abnormalities in children referred to the children’s epilepsy surgery service (CESS) in a single-UK centre and determine associations with epilepsy type and aetiology. This was a review of the CESS...

Normative database of OCT measurements in children

This study aimed to establish a normative database of optical coherence tomography (OCT) (Cirrus SD-OCT) parameters and to investigate if gender, ethnicity and axial length affect these measures by evaluating the effects of age and spherical equivalent refraction (SER) in...

Moorfields International refractive symposium

The Moorfields International refractive symposium covers contemporary vision correction surgery to surgeons in the UK and around the world. Taking place on Thursday 24 April at the Royal College of Physicians in London (08:30 - 17:45), the symposium aims to...

Early biomarker for paraneoplastic retinopathy

This informative case series evaluates 4 eyes of 2 patients presenting with rapidly progressive vision loss secondary to cancer-associated retinopathy. The authors identified a distinct spectral-domain optical coherence tomography structural feature termed the angular sign of Henle fibre layer hyperreflectivity...
