Ocular electrophysiology

A 34-year-old woman, who is a CEO in a multinational firm, has been losing vision over the last 12 months. She has seen her opticians, who initially tried different glasses but could not improve things. Clinical examination is unremarkable. How...

OCTA to measure surgical haemodynamic changes

This study used the optical coherence tomography angiography (OCTA) technique to evaluate possible haemodynamic changes after horizontal rectus muscle surgery in 32 eyes of 16 patients; nine male, seven female. Recession / resection surgery was undertaken for two horizontal rectus...

This study used the optical coherence tomography angiography (OCTA) technique to evaluate possible hemodynamic changes after horizontal rectus muscle surgery in 32 eyes of 16 patients; nine male, seven female. Recession / resection surgery was undertaken for two horizontal rectus...

Cataract extraction and microperimetry

In this study, the authors assessed retinal sensitivity before and after cataract extraction, in an effort to understand how lens opacities may affect microperimetry results in glaucoma and macular diseases. Thirty patients awaiting cataract extraction were examined and their lens...

LACTOSE control score for exotropia

The purpose of this study was to determine the extent of change in control over multiple measurements in a single clinic visit using the Look and Cover, then Ten seconds of Observation Scale for Exotropia (LACTOSE) scoring system in patients...

Using MRI to assess normal variation in optic chiasm anatomy

The authors present an MRI study including 61 MRI scans using a 1.5 T with slice thickness of 1 or 5mm and the sequence showing the highest resolution of the chiasm. A predetermined set of measurements were taken in a...

Muscle insertion measurement by ultrasound biomicroscopy

The aim of this study was to evaluate the accuracy of ultrasound biomicroscopy (UBM) preoperatively and postoperatively in patients having primary horizontal muscle surgery. Sixteen eyes of 15 patients with concomitant horizontal strabismus were evaluated; mean age 21.1 ±3.3 years,...

Prism cover test variances

The purpose was to establish the inter-examiner variability and agreement between more than two examiners assessing children and adult patients. The study involved four experienced examiners. The alternate prism cover test (APCT) was conducted at near and distance in 41...

Use of Bagolini filter bars

The authors measured the percentage light transmission of filters on different Bagolini filter bars to evaluate whether a difference exists in density of suppression or strength of abnormal binocular single vision (BSV). A Sekonic dual spot photometer was used to...

Accuracy of AS-OCT muscle insertion measurements

Anterior segment - optical coherence tomography (AS-OCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of AS-OCT for locating horizontal extraocular muscle insertions after strabismus surgery...

Accuracy of ASOCT muscle insertion measurements

Anterior segment optical coherence tomography (ASOCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of ASOCT for locating horizontal extraocular muscle insertions after strabismus surgery in...

DIY IOP – does it work?

Measuring intraocular pressure (IOP) plays a major role in glaucoma care as IOP is a parameter, along with visual field progression and optic disc cupping used to assess treatment effect. While Goldmann tonometry (GAT) is the gold standard, it only...
