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...
ESASO Course Series Vol. 4 Optical Coherence Tomography
This book, which is the latest volume from the European School for Advanced Studies in Ophthalmology (ESASO) course series, is a revelation and joy to review. This compact volume provides an introduction and an update to the most recent technological...
Diagnostic accuracy of enhanced depth imaging OCT in children
The authors present the findings of a retrospective cross-sectional case series. Cases were identified using a treatment register having been evaluated in a set one-year period. Two ophthalmologists acted as masked image examiners for enhanced depth imaging optical coherence tomography...
Metamorphopsia in idiopathic epiretinal membranes
The Amsler grid is commonly used for self-monitoring, but is qualitative and has low sensitivity. The M-chart reduces the amount of spatial redundancy (‘filling in’) in the Amsler grid. The Orientation Discrimination (OD) test studied in this paper consists of...
Comparison of bleb grading and IOPs
The purpose of this study was to compare a novel anterior segment optical coherence tomography (AS-OCT) bleb grading system with a clinical bleb grading system (Moorfields) and both with intraocular pressure (IOP) levels following trabeculectomy surgery. The authors developed a...
Systemic screening in adnexal lymphoma
This is a retrospective review of 119 patients diagnosed with ocular adnexal lymphoma, 85 of whom had primary adnexal disease and 34 had previously been diagnosed with lymphoma outside the ocular adnexa. Sixty-eight of the primary and 24 of the...
OCT in peripheral corneal thinning
This small retrospective study used high resolution optical coherence tomography (OCT) Heidelberg Spectralis to identify features which could determine the underlying aetiology of peripheral corneal thinning. Ten patients were included; five with diagnoses of degenerative peripheral thinning; Terrien’s marginal degeneration...
Changes in Japanese eyes after laser peripheral iridotomy
The aim of this study was to evaluate laser peripheral iridotomy (LPI) induced changes in anterior segment parameters, using the anterior segment optical coherence tomography (ASOCT). Seventy-two subjects of Japanese ethnicity with primary angle closure suspect (PACS), primary angle closure...
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...
Optical coherence tomography in patients exposed to vigabatrin
Vigabatrin is used to treat epilepsy and can lead to increased levels of gamma-aminobutyric acid (GABA) in the brain and in the retina leading to binasal visual field defects. Although not the first line of treatment for adults it is...
