Shafi Balal on predicting keratoconus progression

In this interview, section editors Nima Ghadiri and Arun James Thirunavukarasu ask Ophthalmic Surgeon and NIHR Doctoral Fellow Shafi Balal about the development of his AI model for predicting keratoconus progression risk, with the longer-term objective of using AI on...

SS-MIOCT for suture depth

The authors describe a case in which swept-source microscope-integrated OCT (SS-MIOCT) was used to directly visualise and evaluate key suturing-related steps of strabismus surgery in real time. Using SS-MIOCT, the surgeons could visualise the precise depth of the needle through...

Comparison of SS-OCT and SD-OCT in polypoidal choroidal vasculopathy

Swept source OCT (SS-OCT) is known to have a longer wavelength than spectral domain OCT (SD-OCT), allowing deeper penetration into retinal and choroidal layers. The aim of this study was to investigate whether SS-OCT is superior to SD-OCT in imaging...

Orbis teams up with the Alcon Foundation and OMEGA to improve eyecare in Zambia

The Orbis Flying Eye Hospital returns to Zambia for a three-week training project in Lusaka coinciding with World Sight Day on October 12.

Neurotrophic keratitis

The authors present an overview of the aetiology, diagnosis, current and future management options of neurotrophic keratitis. This is a degenerative corneal disease that occurs following the compromise of trigeminal innervation, leading to hypoesthesia and / or anaesthesia. The aetiology...

Lucentis for pseudophakic CMO

Pseudophakic cystoid macular oedema (CMO) develops angiographically in up to 20-30% after uneventful phacoemulsification. This study aimed to evaluate the potential efficacy and safety of intravitreal ranibizumab in patients with pseudophakic CMO after cataract surgery. Seven eyes were included in...

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,...

Extraocular muscle OCT

The goal was to evaluate the use of the Heidelberg anterior segment optical coherence tomography (AS-OCT) to image extraocular rectus muscle insertions and to expand the use of the AS-OCT to also image vertical rectus muscles. The authors evaluated inter...

OCT imaging of occluded puncta

This is a description of the use of enhanced depth optical coherence tomography (OCT) to see whether a patent ampulla or canaliculus is detectable in patients with absent or occluded puncta. Nine occluded puncta of six patients with epiphora were...

Reproducible OCT RNFL map in unilateral glaucoma

The aim of the study was to compare the reproducibility of the optical coherence tomography retinal nerve fibre layer (OCT RNFL) thickness map between glaucomatous and fellow normal eyes of unilateral glaucoma patients. The authors carried out a prospective case...

Choroidal and macular thickness in nonarteritic anterior ischaemic optic neuropathy

This study evaluates the choroidal and macular thickness in patients with chronic nonarteritic anterior ischaemic optic neuropathy (NA-AION). Two groups of subjects were compared, group one included 20 eyes with chronic NA-AION and group two, 31 healthy control eyes. The...

Choroidal thickness in ocular sarcoidosis by OCT measurement

This is the first study to evaluate the choroidal thickness in patients with ocular sarcoidosis during the quiescent phase using enhanced depth imaging optical coherence tomography (EDI-OCT) and comparing with normal subjects. Ocular sarcoidosis may affect the choroidal circulation (occlusive...
