Ametropic amblyopia and stereopsis

This study aimed to evaluate the correlations between ametropic amblyopia (hypermetropic – 110, myopic – 30, and astigmatic – 65) and stereopsis in 205 children – mean age of 5.2 years ±1.8. For near stereopsis, significant results were found for...

Resolution of mid-peripheral schisis in x-linked retinoschisis with the use of dorzolamide

X-linked retinoschisis (XLRS) is an early onset hereditary retinal dystrophy. It is caused by mutations of the RS1 gene. Common manifestations of XLRS are schitic lesions at the macula, as well as infero-temporal schisis. Carbonic anhydrase inhibitors have previously been...

Correlation between structural and functional status of optic nerve and retina in multiple sclerosis

Multiple sclerosis (MS) involves autoimmune inflammatory demyelination and axonal degeneration in the central nervous system. Investigation of the retina and optic nerve head (ONH) is an ideal way to visualise this demyelination. This study investigates the functional and structural properties...

A ciliary body tumour

The authors describe a case report of a 60-year-old woman found to have advanced angle closure glaucoma in her right eye and appositional closure of half of the left eye and no glaucoma. The patient had previously undergone two trabeculectomies...

Cost-effectiveness of femtosecond cataract surgery

Femtosecond laser-assisted cataract surgery has become increasingly popular due to the reported benefits of increasing precision and reproducibility of capsulorrhexis, less power and manipulation required during phacoemulsification, better corneal wound architecture, and the ability to place precise arcuate keratotomy incisions...

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...

Risk factors and untreated POAG

The authors examined 50 untreated open angle glaucoma patients to determine if there was an association between the level of glaucomatous damage and documented risk factors. In this study the authors measured the extent of morphologic and functional glaucomatous damage...

Pars plana vitrectomy for vitreomacular traction syndrome

This paper presents a meta-analysis and systematic review of the safety and efficacy of vitrectomy for vitreomacular traction (VMT), based on 21 eligible articles from 460 identified. A strength of this study is that it provided pooled analysis across a...

Testing near or distance visual acuity for change during amblyopia therapy

In this study, the authors aimed to determine if any differences occurred between near and distance visual acuity (VA) in a cohort of childhood untreated amblyopia. They recruited 54 patients with mean age 4.9 years, SD 0.44. Mean VA in...

Is thrombolytic treatment warranted for central retinal artery occlusion?

Central retinal artery occlusion (CRAO) is a subtype of acute ischaemic stroke which results in severe visual loss. Acute CRAO is equivalent to a brain acute ischaemic stroke (AIS), as the obstruction of the central retinal artery (CRA) causes end-organ...

Long-term outcomes of deep anterior lamellar versus penetrating keratoplasty for keratoconus

This is a retrospective consecutive and comparative case series of keratoplasties (228 deep anterior lamellar keratoplasties (DALKs) and 274 penetrating keratoplasties (PKs)) in a single centre by one surgeon in France, between 1993 and 2021. Graft survival was 96.7% at...

Contrast sensitivity comparisons for Pelli Robson, Hiding Heidi and Double Happy tests

The authors aimed to compare contrast thresholds and measure agreement across current paediatric assessment of contrast sensitivity with Hiding Heidi and Double Happy contrast sensitivity tests vs. the gold-standard Pelli Robson chart. Reduced contrast levels were similar under different light...
