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...

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...

Changes in phoria measurements after physical activity

This study aimed to evaluate effects of physical activity (aerobic and anaerobic) on the latent eye deviation. The study recruited 20 competitive soccer players (10 myopes (mean -0.63D) and 10 emmetropic: 19 males), who underwent a total 90-minute exercise of...

My ophthalmic elective: Lerdsin Hospital, Thailand

My decision to undertake elective in Thailand was made to help broaden my horizons on ophthalmic conditions and practices. Additionally, I hoped to improve my Thai medical vocabulary to communicate with Thai patients fluently. As I got an opportunity to...

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...

Central corneal and epithelial thickness measured by Fourier domain OCT

This study examined intraobserver and interobserver reproducibility of corneal thickness (CT) and epithelial thickness (ET) measurement of Fourier domain OCT (RTVue) in 23 healthy volunteers. RTVue is capable of producing 26,000 A scans per second with depth resolution of 5µm....

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...
