Scheimpflug vs. OCT in measuring corneal thickness
The authors report on the reproducibility and repeatability of corneal thickness measurements using three different Scheimpflug imaging cameras (Pentacam, Sirius and Galilei) and one Fourier-domain optical coherence tomography (OCT) system (RTvue-100). The rationale for this study is that corneal thickness...
Density of cataract and its influence on retinal nerve fibre layer thickness
The aim of this study was to further define and model the influence of cataract on spectral domain optical coherence tomography (SDOCT) image quality and retinal nerve fibre layer (RNFL) thickness measurements. OCT quality is influenced by opacities in the...
Time domain vs. spectral domain in the measurement of the optic nerve head
The authors describe a prospective study of 40 participants (20 healthy and 20 with glaucoma) enrolled to compare the measurements of the optic nerve head (ONH) parameters given by time domain (TD) and spectral domain (SD) optical coherence tomography (OCT)....
ICG TTT for retinoblastoma
Transpupillary thermotherapy (TTT) is a specific form of ocular TT using infrared radiation (diode laser). Indocyanine green (ICG) is also used to achieve the optimal phototherapy effect in eyes with minimal pigment. Twenty-one patients with 42 retinoblastomas in 30 eyes...Your 101 guide to interpreting the Pentacam®
Anterior segment tomography produces a three-dimensional assessment of anterior and posterior corneal structures. The Pentacam uses rotating Scheimpflug imaging to generate cross-sectional scans of the cornea and anterior chamber, essential for detecting ectasia, refractive surgery screening and longitudinal monitoring. However,...Contemporary glaucoma therapy: spoilt for choice
The goal of glaucoma management is to prevent visual loss and disease progression in the patient’s lifetime through effective lowering of intraocular pressure (IOP), the primary modifiable risk factor in glaucoma. Sustained and consistent IOP reduction is key to halting...Ophtherminator 3 - Rise of the Machines
“Bring back life form, priority one, all other priorities are rescinded.” Film buffs will spot this as a chilling quote spoken by Ash (Ian Holm) from the classic sci-fi horror movie Alien (1979). Ash (spoiler alert) is a Hyperdyne Systems...The clues of the eye – what is medical ophthalmology?
The author looks at the increasingly significant role of medical ophthalmologists and the importance of integrative healthcare. The eye is a remarkable organ, and for decades we have been discovering intimations of pathology existing elsewhere in the body [1] simply...
Morning glory syndrome associated with PHPV
This is a retrospective review of the medical records of 85 eyes / 74 patients diagnosed as morning glory syndrome (MGS) in the clinic between November 2009 and November 2012. Twenty two eyes of 19 patients diagnosed as having MGS...
Multimodal imaging in wet AMD
This novel study set out to determine grader agreement levels of various retinal imaging techniques, commonly used in the diagnosis of wet age-related macular degeneration (AMD). Images from 52 eyes were by examined by two different observers. All images were...
Retinal ischaemia on OCTA and diabetic retinopathy grade
The authors quite rightly point out that quantification of retinal ischaemia has the potential to serve as a biomarker for diabetic retinopathy disease progression. They set out to investigate the relationship between area of ischaemia on a swept source OCTA...
