Vision screening opinion

The aim of this paper is to describe experts’ perceptions of best practice guidelines and competency frameworks for visual screening in children. A focus group of approximately 75 minutes duration consisted of five orthoptists and two paediatric ophthalmologists with more...

Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

Vision measurements vs. self-rating

The aim of this study was to evaluate the association between self-rated vision status and tests of visual acuity, contrast sensitivity, stereoacuity, bilateral visual field and self-reported visual function in specific domains of near and far vision. The goal was...

High-fluence collagen cross-linking

The authors treat seven eyes with progressive keratoconus with a high energy (18mW) for five minutes delivering a total energy similar to that suggested by the original Dresden protocol (3mW for 30mins). All eyes had a thickness >400µm following epithelial...

Fixed or variable Muller’s muscle resection

This is a retrospective analysis of 60 patients who underwent posterior approach ptosis surgery utilising a Muller’s muscle resection. The study compares those who underwent a fixed resection length of 7mm of Muller’s muscle with those having a variable resection...

Repeated ptosis surgery

The purpose of this study was to evaluate the amounts of surgery for the treatment of residual or recurrent simple congenital ptosis and to investigate the relationship between long-term surgical success rates with clinical and surgical factors. This was a...

Two bifocals and a trifocal

The authors compare the optical outcomes of two bifocal intraocular lenses (AcrySof ReSTOR +2.50 Diopter [D] add +3.0D add) with a trifocal lens (AT LISA tri 839MP). The optical qualities of the lenses were quantified by measuring the modulation transfer...

Vertical disparity effects on horizontal fusion

This study was designed to investigate the effect of induced vertical disparity by prisms on horizontal fusional reserves at near distance. One hundred and seventy students were recruited and vertical disparity was induced by small vertical prisms of 0.5 and...

Sagging eye syndrome surgery

This retrospective study evaluated outcomes of surgery for patients with sagging eye syndrome (SES) from 1994 to 2014, to determine recurrence rates of strabismus. The study identified 103 cases; 93 requiring surgery for symptomatic small angle strabismus and 10 requiring...

Intraocular pressure reduction after cataract surgery

Several studies have shown the efficacy of cataract surgery in lowering intraocular pressure (IOP), especially in angle closure glaucoma compared to open angle. A total of 156 eyes of 109 patients (without glaucoma or with medically controlled glaucoma) were included....

Screening and adherence to glaucoma care in Enugu, Nigeria

The authors present the findings of a cross-sectional survey of participants diagnosed with glaucoma during free eye screening. A total of 830 participants were screened from two outreaches:182 new glaucoma cases were diagnosed (63 glaucoma and 119 glaucoma suspects). There...

Surgery for unilateral superior oblique palsy

This study evaluates the amount of effectiveness of inferior oblique myectomy in primary position, lateral gaze and head tilt, and the effect on improving extent of abnormal head posture. The study included 39 patients; 22 male, 25 left-sided palsy and...
