Effects of blood donation on the physiology of the eye
Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...
Retinal vessel diameter in pseudoexfoliation
Pseudoexfolation (PEX) is characterised by deposition of fibrillary extracellular material on ocular and extraocular tissue. Studies have shown that deposition in vascular structures cause hypoxia and ischaemia. In the eye, a decrease in blood supply to the optic nerve can...
MPH treatment effect in ADHD on choroidal vascular index
In this study the authors aimed to investigate the choroidal vascular index (CVI) in treatment-free children with ADHD, children regularly taking methylphenidate (MPH) and healthy controls. This was a prospective cross-sectional study of 52 patients with newly diagnosed ADHD, 46...
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...
Association between COVID-19 restrictions and accelerated myopia progression
A retrospective case review aimed to evaluate the association between home confinement and progression of myopia in Argentina during 2020. Data was collected using an online survey of ophthalmologists throughout Argentina. The inclusion criteria included being five to 18-years-old, found...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...
Risk stratification to reduce intraoperative cataract surgical complications
The authors prospectively collected data on 1135 consecutive patients undergoing cataract surgery. They were risk stratified according to categories – A (no additional risk factors, 0 points), B (vitrectomy, corneal scarring, small pupil less than 3mm, shallow anterior chamber less...
OCT choroidal signs for congenital retinal pigment epithelium hypertrophy
Congenital hypertrophy of the retinal pigment epithelium (CHRPE) on ocular coherence tomography (OCT) has the characteristic sign of RPE thickening and hyper reflectivity. However, the underlying choroid characteristics remain under researched. This retrospective study utilised data from an ophthalmic oncology...
Photoscreening comparison
The A09/S09 photoscreener contains a fixation target of flashing lights (as for the S04) plus a smiley face which is new. Concerns were raised that the smiley face may stimulate less accommodation than the S04 attention lights and therefore potentially...
Choice of cycloplegia regime
The purpose of this randomised control trial (RCT) was primarily to compare the refractive outcome of atropine 0.5% (A) instilled twice daily at home 2.5 days before measurement versus two drops of 1% cyclopentolate (CC) in one eye versus one...
Eye movements in children with strabismus +/- amblyopia
The aim of this study was to detect eye movement recording abnormalities using different paradigms in children with strabismus in the absence or presence of amblyopia and compare these findings with age-matched children without strabismus. One hundred children were recruited...
