Visual fields and OCT in hydroxychloroquine retinopathy

It has been recommended that patients on hydroxychloroquine be monitored regularly for retinopathy. However, there has not been an agreement as to the best screening test for hydroxychloroquine toxicity, which may include visual fields (VF), fundus autofluorescence, spectral domain optical...

Two bifocals and a trifocal

The authors compare the optical outcomes of two bifocal intraocular lenses (AcrySof ReSTOR +2.50 Diopter [D] add +3.0D add) with a trifocal lens (AT LISA tri 839MP). The optical qualities of the lenses were quantified by measuring the modulation transfer...

Biometry measure after cycloplegia

The authors investigated optical biometry in an Indian paediatric population on normal and cataract paediatric eyes and studied the effect of cycloplegia on different parameters measured in these eyes. This was a prospective study of 76 eyes aged five to...

Endothelial cell loss using different graft injectors in DMEK

This study aimed to investigate endothelial cell loss between two injector systems in descemet membrane endothelial keratoplasty (DMEK) grafts; a glass injector – modified Jones tube and a plastic injector – closed system IOL injector, the Viscoject 2.2 system. DMEK...

OCT-A imaging in Grave’s orbitopathy and orbital decompression

In this case series of 12 patients and 24 orbits, the authors describe the changes in the optic nerve and peripapillary blood vessel density in patients with moderate to severe Grave’s Orbitopathy (GO) undergoing orbital decompression. The patients undergoing orbital...

Demyelinating optic neuropathy

Introduction Optic neuritis (ON) is an inflammatory process affecting the optic nerve. After glaucoma, it is the most common optic neuropathy affecting patients under the age of 50. The usual presentation of typical ON is unilateral subacute loss of vision...

Clinical Observation Days Pave Way for Next Generation of Optometrists

Optometry students at Glasgow Caledonian University have taken part in a series of clinical observation days at one of the UK’s leading eye surgery clinics, as part of a new programme giving student optometrists experience of modern day surgical practice.

OCT in peripheral corneal thinning

This small retrospective study used high resolution optical coherence tomography (OCT) Heidelberg Spectralis to identify features which could determine the underlying aetiology of peripheral corneal thinning. Ten patients were included; five with diagnoses of degenerative peripheral thinning; Terrien’s marginal degeneration...

OCTA optic disc measurement differences between glaucoma and pituitary macroadenoma

This prospective case-control study aimed to assess the potential of optical coherence tomography (OCT) and OCT angiography (OCTA) in distinguishing between glaucoma and pituitary macroadenoma based on optic disc appearance. Thirty-one patients (23 with glaucoma, eight with pituitary macroadenoma) were...
