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...Simulation in ophthalmology: a pedagogic viewpoint
The advent of simulation technology has enhanced modern medical training. The first utilisation of simulation was in 1929 where Edward Link used this concept to develop a mechanical flight simulator [1]. Industries such as aviation, nuclear power and the military...
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...
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...
Orbital fat density as a diagnostic tool in pre-septal and orbital cellulitis
This study aimed to evaluate the usefulness of orbital fat density in identifying post-septal involvement when initial differential diagnosis between orbital (OC) and periorbital (POC) cellulitis is unclear. This was a retrospective study of 57 patients with clinical diagnosis of...
Normative reference values for optic nerve sheath diameter in children
The purpose of this study was to measure optic nerve sheath diameter (ONSD) in paediatric patients without pathology using brain CT performed for various reasons and to provide normal tomographic reference values. This was a retrospective study of CT scans...
Which cover test method is the best starting point for prescribing temporary prisms?
A retrospective review of medical records was completed, identifying consecutive patients prescribed Fresnel prisms for diplopia, assessed using both simultaneous prism and cover test (SPCT) and prism and alternate cover test (PACT) by a single orthoptist over a 36-month period....
