The influence of refraction correction in swept source AS-OCT measurement parameters

Anterior segment (AS) optical coherence tomography (OCT) is the non-invasive technique used to analyse detailed cross-sectional images of the anterior structures of the eye. Swept source (SS) OCT at 1310nm can penetrate deeply into the eye with low levels of...

The treachery of images – making sense of OCT imaging

In 1929 Belgian surrealist Rene Magritte produced his painting La Trahison des Images. It depicted an old fashioned pipe for smoking tobacco and underneath were the words “ceci n’est pas une pipe”, this is not a pipe. You may wonder...

In conversation with Robert Henderson

Revolutionary eye treatments offer hope for children facing blindness from CLN2 batten disease. Robert Henderson discusses this, and his use of Heidelberg Engineering’s Spectralis device to better combat it. Pioneering research from Great Ormond Street Hospital (GOSH) and the University...

The role of spectral-domain OCT RNFL in revealing a pituitary adenoma with atypical visual fields

Pituitary adenomas classically cause bitemporal hemianopia by compressing the optic chiasm. However, in some cases, the pattern of visual field loss may be atypical and mimic homonymous hemianopia, depending on the direction and extent of tumour expansion. Spectral-domain optical coherence...

IOP and reversibility of RPE detachment

The authors describe how three patients with retinal pigment epithelium (RPE) detachment showed a reduction or disappearance of an RPE detachment immediately following prone dark room test (PDRT). The authors performed spectralis OCT on 140 angle closure subjects before and...

ABDO response to free sight tests for special schools

The Association of British Dispensing Opticians (ABDO) has issued the following response to government’s and NHS England’s announcement on free sight tests for special schools.

PREVIEW: International SPECTRALIS Symposium – AND BEYOND

The International SPECTRALIS Symposium (ISS) marks its 21st anniversary with an exciting new chapter in Heidelberg, Germany, just steps away from the headquarters of Heidelberg Engineering. Recognised as one of the most prestigious scientific imaging conferences, ISS 2025 will bring...

The structure function relationship in 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...

Climb every mountain!

Recently, on a weekend break away in the beautiful Cairngorms, I foolishly let it be known that I had never actually climbed a ‘Munro’, despite having moved from Northern Ireland to Scotland nearly 17 years ago! For the unaware, Munros...

Optical Coherence Tomography: A Clinical and Technical Update

This book is a comprehensive review of the clinical and scientific aspects of optical coherence tomography (OCT). The 255 pages are divided into 11 chapters, each written by a different group of authors. Part I provides viewpoints on the clinical...

RPE tears after intravitreal Lucentis

The current hypothesis regarding retinal pigment epithelium (RPE) tears is the contraction and fibrosis in choroidal neovascularisation (CNV) tissue after anti-VEGF therapy can induce rips in the overlying RPE. This South Korean study aimed to identify the association between RPE...

Epiretinal membranes in uveitic macular oedema

Epiretinal membrane (ERM) formation in uveitic macular oedema is a fairly common structural complication of the retina. The authors describe a retrospective case series of 104 eyes of 77 patients with uveitic macular oedema from a tertiary centre. The treatment...
