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...

What’s next in retinal imaging? Faster, deeper and full-on

Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...

25 years of OCT

David Huang first described optical coherence tomography (OCT) in 1991, in his seminal paper on the subject in Science. This method developed the work of others on ophthalmic interferometry, which essentially showed that measuring reflected light could be used to...

OCT angiography sign after whiplash

Berlin’s oedema is a rare condition following blunt ocular injury and a rare finding after whiplash injury. This case describes a 48-year-old male who suffered a seventh vertebrae fracture from a traffic accident. Two days later, decreased left eye visual...

Hypothyroidsim and acute central serous chorioretinopathy – is there a link?

This cross-sectional study included 71 consecutive acute central serous chorioretinopathy (CSC) patients and 70 age-matched healthy control subjects. Systemic findings, including serum levels of thyroid hormones, thyroid stimulating hormone (TSH), mean arterial pressure (MAP), pulse rate, serum lipid levels and...

Choroidal defects in neurofibromatosis

The aim of this study was to investigate the frequency of choroidal abnormalities using infrared reflectance imaging with optical coherence tomography (OCT) in paediatric patients with neurofibromatosis (NF) type 1. Thirty-eight eyes of 19 patients were reviewed. NF1 was diagnosed...

Subfoveal choroidal thickness and PCV

This report studies the prognostic factors for visual improvement and the need for additional treatments at one year after the initial combination therapy of intravitreal ranibizumab injection or intravitreal aflibercept injection followed by PDT in eyes with PCV. Fifty-six eyes...

Birdshot chorioretinopathy: an important differential

Birdshot chorioretinopathy (BSCR) is a relatively uncommon cause of posterior uveitis which often has a relapsing and remitting course [1,2]. We present a case which demonstrates how remission can be obtained for several years using cyclosporine. Case report A 44-year-old...

Uveal melanoma

Uveal melanoma is the most common primary intraocular tumour. However, they are still rare, with an incidence of 2-8 per million [1]. The presence of a choroidal naevus is a risk factor for uveal melanoma [1]. Patients with choroidal lesions...

Sex hormones in males and females with central serous chorioretinopathy

This study was aimed to assess the role of sex hormones in male and female patients with central serous chorioretinopathy (CSC), a disease with a pronounced male predilection. Two hundred and six patients, 183 males (mean age 52, median 52,...

The approach to angle-closure glaucoma

Further to my last article in Eye News (print issue) describing the diagnostic approaches to various clinical scenarios in glaucoma, the approach to angle-closure glaucoma (ACG), a situation terrifying for patient and registrar alike, will be discussed. Please refer to...

Retinoblastoma mortality associations with choroidal and optic nerve invasion

The authors present a retrospective cohort study. Data was extracted from the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) database, based in the US and founded in 1973. Cases of retinoblastoma were extracted using the inclusion criteria of...
