Assessing failure of laser coagulation treatment for type 1 retinopathy of prematurity

The authors present the findings of a retrospective study to examine the cause of treatment failures in type 1 retinopathy of prematurity (ROP). They reviewed the medical charts of all infants with persistent disease post laser treatment at Uppsala University...

Oral glycerol effect on anterior chamber depth during cataract surgery

The authors present the findings of a controlled clinical trial where cataract patients having surgery for both eyes at least seven days apart were given oral glycerol preoperatively when operating on the right eye. This meant that the left eye...

Practical Handbook of OCT (Retina, Choroid, Glaucoma)

With the rapid development and expansion in the usage of optical coherence tomography (OCT) technology there is always demand for a new OCT publication on the bookshelves. The operation and acquisition skills required are more easily acquired than for the...

The interpretation and use of ultrasound biomicroscopy (part 1)

Ultrasound Biomicroscopy (UBM) has become increasingly important for the diagnosis of a variety of anterior segment pathologies. Most ophthalmologists are familiar with conventional B-scan ultrasonography techniques, which operate at lower sound frequencies (7.5 to 20MHz). UBM is an ultrasound technique...

A comparison of light sources in retinal imaging

Before starting to talk about the light sources present in retinal imaging, it is necessary to start from the base: the light. Light is an electromagnetic wave whose smallest part is the photon (or quantum of light). A high frequency...

Mastering Vision Precision: Enhancing IOL Power Prediction with High-Resolution Anterior Segment Imaging

RCOphth (The Royal College of Ophthalmologists) Management of Diabetic macular oedema: state-of-the-art

Talks will include: 1) OCT biomarkers in DMO - what adds value in clinical-decision making? - Christiana Dinah, Consultant Ophthalmologist and medical retina specialist, London 2) Debate: When should you switch treatment in DMO? versus late - Deepali Varma, Consultant...

Zeiss Forum

The tech column this issue reports on the features and experience of using the Zeiss Forum software. I have overseen the installation, troubleshooting, training and use of the software over the last two years. As both a consultant specialising in...

Retinal structural features of CMV retinitis

Confocal adaptive optics (AO) technology has enabled cellular level retinal imaging, including imaging of photoreceptors and blood flow. Adaptive optics scanning laser ophthalmoscopy (AOSLO) is a technology that provides high resolution and high contrast retinal images by correcting ocular aberrations....

Swept-source OCT for measuring peripheral anterior synechiae

The authors report on a cross-sectional study looking at swept-source optical coherence tomography (SS-OCT) for measuring the area and degree of peripheral anterior synechiae (PAS) in patients with angle closure glaucoma. The SS-OCT is commercially available, has a laser wavelength...

OCT biomarkers in asymmetric anti-VEGF response in bilateral diabetic macular oedema

This study aimed to identify optical coherence tomography (OCT) biomarkers for predicting response to anti-VEGF treatment in diabetic macular oedema (DMO). Bilateral DMO patients with asymmetric response to a loading dose of anti-VEGF (ranibizumab / aflibercept) treatment were retrospectively studied....

Use of international interocular difference thresholds for optic neuritis diagnosis in clinical practice

Multiple sclerosis (MS) is the most common non-traumatic cause of disability in young people, and visual symptoms can be the initial manifestation in up to 20% of cases. Retinal examination can be helpful in making the correct diagnosis. The latest...
