Bardet Biedl refractive error

This is a retrospective cross-sectional study of 45 patients with genetically diagnosed Bardet Biedl syndrome. Patients with biallelic defects in any gene known to cause Bardet Biedl syndrome were eligible for inclusion. Patients underwent cycloplegic refraction and keratometry. The mean...

Systematic review of management options for intermittent exotropia

The authors conduct a robust systematic review of the literature to report evidence on non-surgical and surgical treatment options for intermittent exotropia – divergence excess and basic intermittent exotropia types. Discussion centres on (1) optical correction of refractive error with...

The use of virtual reality in paediatric ophthalmology

The purpose of this study was to investigate the utility of virtual reality (VR) in the broader field of paediatric ophthalmology with review of examination, screening, diagnosis, prevention and treatment. This review also explores the potential of eye tracking used...

International Ophthalmology Conference 4th Edition

A transformative experience awaits at the “4th Edition of International Ophthalmology Conference” (IOC 2026), taking place from March 23-25, 2026, in Singapore and Virtually. Anchored in the theme "Unlocking New Frontiers in Vision Science and Eye Care", this global platform...

Prevalence of strabismus, nystagmus and risk factors in children and adolescents born preterm with and without retinopathy of prematurity

This is a retrospective study of 949 children (11.21 +/-3.92 years, 495 females). They were divided into 6 groups based on gestational age (GA) with/without retinopathy of prematurity (ROP) and with/without treatment of ROP, alongside full-term babies as a control...

Self refracting – child’s play?

Uncorrected refractive error was the leading cause of vision impairment in the world in 2010. Although refractive error may be safely and effectively corrected with spectacles, lack of well-trained refractionists in settings of limited resources may be a major barrier....

OCT positioning regimen in macular hole surgery

The authors set out to evaluate an OCT-based positioning regimen for macular hole surgery. Patients were advised to maintain prone positioning until the hole was confirmed to be closed based on daily OCTs. Surgery consisted of 23-gauge phacovitrectomy with internal...

Effects of ‘inverted U method’ Nd:YAG laser posterior capsulotomy on anterior segment and IOL tilt

The study aimed to investigate the effects of the ‘inverted U method’ Nd:YAG laser posterior capsulotomy on anterior segment parameters, decentration and tilt of intraocular lens (IOLs) and visual acuity in 76 patients with posterior capsular opacification (PCO) after previous...

Normative database of OCT measurements in children

This study aimed to establish a normative database of optical coherence tomography (OCT) (Cirrus SD-OCT) parameters and to investigate if gender, ethnicity and axial length affect these measures by evaluating the effects of age and spherical equivalent refraction (SER) in...

Principles of contact lens fitting in keratoconus

Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...

Biometry and IOL choice errors

In the next instalment of this series I focus on problems associated with biometry and intraocular lens (IOL) selection for cataract surgery. I have taken previous medicolegal cases I have dealt with and tried to extract some learning points and...
