The refractive index in the eye lens – implications for clinical practice and optical design

The eye may appear to be a comparatively simple organ and yet its optical system is complex and continues to be a source of investigation and research. The major optical elements are considered to be the cornea and the lens...

OXSIGHT Onyx – A sight-enhancing wearable

The Onyx is a newly-released (late 2021) wearable with a powered magnifier to assist those with central vision impairment. Unlike the previously covered wearable devices, this enhances existing sight. The unit can either be held against the eyes when needed,...

What you learn after performing 10,000 cataracts

What do you do when the anterior chamber shallows, or the zonules give way? How do you handle the stubborn epinuclear plate? Raymond Radford shares the benefit of his experience when dealing with tricky cataract surgery. Firstly, you realise you...

We are pleased to invite you to the 21st edition of the International SPECTRALIS® Symposium – and Beyond (ISS), which will be held for the first time in Heidelberg, Germany, on June 13-14, 2025, at the new Congress Center, just...

The choroid in pregnancy

During pregnancy there can be different types of ocular changes including a decrease in corneal sensitivity, increase in central corneal thickness and curvature, decrease in intraocular pressure, central serous chorioretinopathy and ocular blood flow. Advances in ophthalmic imaging devices has...

TowardPi Brings Next-Generation OCT/A to the UK

TowardPi, a fast-growing leader in ophthalmic imaging, has entered the UK market with its advanced swept-source OCT (SS-OCT) and OCT angiography (OCTA) systems. Distributed exclusively by Mainline Instruments, TowardPi is already well-established in Asia and is recognised for pioneering the...

Practice patterns of uveal melanoma management with Iodine-125 brachytherapy

With the 2006 Collaborative Ocular Melanoma Study Group (COMS) study demonstrating no difference in survival outcomes for participants randomised to either iodine-125 brachytherapy or enucleation, the majority of primary uveal melanomas in the United States are now treated with brachytherapy....

Aqueous misdirection: a case series of unexpected surgical complications

Aqueous misdirection (AM), also known as malignant glaucoma, is a form of secondary glaucoma that typically presents with shallowing of the anterior chamber (AC), raised intraocular pressure (IOP), and reduced visual acuity (VA) in the presence of patent peripheral iridotomies...

Bovine pericardium scleral patch graft associated scleritis: Ahmed valve implant for pupillary block glaucoma

Processed bovine pericardium is a lyophilised collagen sheet used as a surgical armamentarium. It renders the material antigenically inert with minimal inflammation [1]. Sclera patch pericardium graft (Tutopatch) is a collagenous membrane derived from solvent preserved, irradiated bovine pericardium [2]...

Comparison of central laminar thickness in optic neuropathy and normal eyes

The study compares central laminar thickness (LT) among patients with glaucomatous optic neuropathy (GON), patients with non-GON and normal subjects. The non-GON group comprised eyes with demyelinating optic neuropathy (ON), anterior ischaemic ON, compressive ON, Leber hereditary ON and traumatic...

Choroidal thickness in ocular sarcoidosis by OCT measurement

This is the first study to evaluate the choroidal thickness in patients with ocular sarcoidosis during the quiescent phase using enhanced depth imaging optical coherence tomography (EDI-OCT) and comparing with normal subjects. Ocular sarcoidosis may affect the choroidal circulation (occlusive...

CFEOM outcomes

This study presents the orbital and cranial magnetic resonance imaging (MRI) findings of patients diagnosed with congenital fibrosis of the extraocular muscles (CFEOM) along with the surgical procedures and outcomes for ocular motility and strabismus. Nine patients are described: three...
