Cataract surgery in corneal disease

Cataract surgery in the presence of corneal disease presents multiple challenges, from determining whether symptoms are lenticular or corneal in origin, to decisions regarding timing of surgery, intraocular lens (IOL) power calculation, IOL selection, surgical technique and perioperative care. Realistic...

“I can see fine. Why do I need my eyes tested?”

Are routine eye examinations really necessary? The author asks whether frequent appointments in low-risk patients with normal results are actually cost-effective. It’s recommended that most people should get their eyes tested every two years.” [1] This message is widely publicised...

Contrast sensitivity in myopic eyes

A classification system has been proposed for myopic maculopathy: grade 0 (no myopic retinal lesions), grade 1 (tessellated fundus), grade 2 (diffuse chorioretinal atrophy (CRA)), grade 3 (patchy CRA), and grade 4 (macular atrophy). Tessellated fundus is defined as the...

Intraocular surgery and dry eye: Understanding the link, minimising the risk and preparing for the future

Dry eye disease (DED) and ocular surface disease (OSD) are increasingly recognised as central factors in contemporary intraocular surgery. As cataract, glaucoma and vitreoretinal procedures advance toward greater refractive precision, patient expectations have risen and tolerance for postoperative visual fluctuation...

Leading eyecare charity Orbis launches a research trial to identify link between vision loss and mental health in children

In 2022, leading eye care charity Orbis published research showing that children with poor vision are more likely to suffer with depression, anxiety, low self-esteem and a reduced quality of life.

In this study, the success rate of treatment for infantile esotropia (IET) patients who had surgery because of under correction after botulinum toxin (BT) is compared to those having primary surgery. The study included 52 patients (27 male) with mean...

OCT in microtropia

The aim of this study was to assess whether OCT could be useful in detecting and documenting fixation in children with microtropia. The study used spectral domain OCT (Cirrus) in 15 patients (10 female, five male) and 10 control eyes....

Would automated pupillometry be a useful addition when assessing acute vision loss?

The authors present a two-part study, the first part being an electronic survey of ophthalmologists and optometrists to identify barriers to the routine clinical use of automated pupillometry and the second, a clinical study comparing the swinging light tests and...

IOP reduction and progression of high myopic glaucoma

This retrospective study of 131 eyes with high myopia (refraction >-6.0 dioptres or axial length >26mm), best corrected vision 20/40 or better, open angle and follow-up period of more than five years, were included from Korea. Based on the intraocular...

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...

Randomised trial of multifocal intraocular lens versus monovision

The authors report on a randomised, multicentre clinical trial comparing the outcomes of Tecnis ZM900 diffractive multifocal intraocular lenses (IOL) versus monovision with Akreos AO monofocal IOL (dominant eye targeted for emmetropia and non-dominant eye targeted for -1 to -1.50...
