Bacterial keratitis through the window of the known unknowns

This review article provides an up-to-date summary of current challenges in research and management of bacterial keratitis. The authors highlight that there is no current agreement on the criteria that should define bacterial keratitis; the role of investigation is unclear,...

QR codes in posters

Sometimes it is nice to read a poster you see at a conference in more detail at a later date. With a little effort you can easily distribute a PDF version of your poster to interested readers by ‘attaching’ a...

Atlas of Wide-Field Retinal Angiography and Imaging

Through extensive illustrations, this book, comprehensively yet concisely, covers the diagnostic speciality of wide-field retinal angiography and imaging. There are 15 chapters with contributions from 29 leading experts in this particular field who are mainly based in the USA, but...

Portable corneal topography – exploration of a prototype

Ophthalmic imaging devices, such as corneal topographers, are not widespread in the developing world. A small device that connects to a smartphone might be a solution to improve developing nation access to corneal imaging. I recently had the opportunity to...

Anisometropia following cataract surgery and its non-surgical treatment

The desired result of cataract surgery is improved visual acuity without the use of spectacles. In practice most patients following initial cataract extraction are likely to be symptomatic of anisometropia giving rise to prismatic effects (anisophoria) and unequal retinal image...

ZEISS receives FDA clearance for CLARUS 700, enabling high-resolution, ultra-widefield imaging with fluorescein angiography

ZEISS's Medical Technology Segment announced that it has received 510(K) clearance from the FDA for the CLARUS® 700, High-Definition, Ultra-Widefield Imaging system for advanced care specialists. CLARUS 700 is the first high-resolution ultra-widefield imaging with true colour and a complete range of fundus imaging modalities, including fluorescein angiography (FA).

Comparison between findings in OCTA and FA in patients with diabetic retinopathy

In this study the authors present a prospective cross-sectional comparative study of typical findings of diabetic retinopathy to analyse the agreement between the image modalities of optical coherence tomography angiography (OCTA) and fluorescein angiography (FA). Fifty-three eyes of 42 patients...

Characteristics of limbal lymphatic vasculature on confocal microscopy

This ex vivo study aims to describe the morphological characteristics of the human limbal lymphatic vasculature using confocal microscopy and immunofluorescence. Twelve corneal specimens are obtained from human donor eyes. These corneal buttons are not suitable for transplantation due to...

Optical coherence tomography – reinventing the eye examination

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...

Scheimpflug images and graft rejection

This study aimed to assess corneal changes using 360-degree Scheimpflug images and pachymetry readings to outline screening parameters, which define graft rejection. Seventeen eyes of 16 patients developed clinically manifest allograft rejection two to 42 months after surgery – those...

Katena Diamond Bi-aspheric indirect lenses

Carleton is pleased to report significant interest and positive feedback on the new extended portfolio of Katena Diamond Bi-aspheric indirect lenses.

Assessing everyday visual function in dry AMD – what matters to the person?

Age-related macular degeneration (AMD) is the primary cause of blindness in the developed world and is accountable for more than one half of sight impairment registrations within England and Wales [1]. AMD is prevalent in people aged 60 years and...
