Are any precautions needed when performing cataract surgery in thrombocytopenic patients?
In this retrospective multi-centre study, charts for 196 eyes of 150 thrombocytopenic patients were reviewed. The mean preoperative platelet level was 73.0 ± 20.5 × 103/μL (median of 76.0 × 103/μL), with a range of 17 to 100 × 103/μL...
Comparing tensile strengths of two scleral fixated intraocular lenses: CT-Lucia and MA60
The authors designed a benchtop model to measure the tensile strengths and resistance to breakage of the haptics and haptic-optic junctions of the CT Lucia 602 (Carl Zeiss, California) and AcrySof MA60 (Alcon Laboratories, Texas) IOLs. For the haptic breakage...
Central fixation testing in microtropia
This study compared the two assessment methods of the 4D prism test and ocular fixation assessment in order to identify micro strabismus with identity. The study included 112 children; 46 males and 66 females. Anisometropia was present in 108 patients...
The rate of realignment of two toric monofocal intraocular lenses (IOL)
This retrospective study used the American Academy of Ophthalmology Registry data to analyse the need of reoperation for realignment within the first year after cataract surgery with a TECNIS or AcrySof monofocal toric IOL implanted during 2016 and 2017. They...
Exotropic angle by PACT vs under translucent cover
The authors aimed to validate the photographic analysis with a translucent cover by comparing the results obtained from this analysis with the angle obtained by prism cover test (PACT) in patients with intermittent exotropia. This was a retrospective review of...
BESTi: a new index to detect subclinical keratoconus
In this multicentre, case-control study, the authors develop a new index, named Boosted Ectasia Susceptibility Tomography Index (BESTi), to detect early cases of keratoconus. This index was derived from multiple logistic regression analysis of 22 variables of tomography scans. The...
Exotropia control score versus angle
The authors aimed to evaluate the relationship between family history and deviation control in intermittent exotropia, and the effects of age, sex, angle and refractive status on deviation control. This was retrospective review of 54 patients aged 7.7 ±4 years...
Treatment of amblyopia by Ghanaian optometrists
In Ghana, optometrists are the primary eyecare professional as a first contact for many patients with amblyopia. This study evaluated practice patterns in the management of amblyopia by optometrists in Ghana. The authors conducted a cross-sectional online survey aimed at...
Symfony and vivity: comparing two EDOF IOLs
This prospective, randomised, double-masked, single-surgeon study compared the visual outcome between two commonly used extended depth of focus (EDOF) lenses, the Tecnis Symfony IOL (Johnson & Johnson Vision) and the Acrysof IQ Vivity IOL (Alcon Laboratories, Inc.). Sixty-nine patients underwent...
Acute comitant esotropia as the presenting sign of diffuse intrinsic pontine glioma
The authors present four children with acute comitant esotropia (AACE) associated with diffuse intrinsic pontine glioma. All were treated with radiation therapy and all subsequently died due to the tumour. Children were aged 5, 5, 4.5 and 11 years. General...
Prevalence and related factors for strabismus and amblyopia in Africa
The aim of this study was to overview the literature in relation to strabismus and amblyopia and associated risk factors in Africa. The review included 24 papers; eight for strabismus and 21 for amblyopia. Sample sizes ranged from 352 to...
