IOL power in short eyes

Prospective analysis of 269 eyes of 269 patients between 2017 and 2020, with axial length (AL) of 22mm or less. New principles for calculating IOL power were recently developed, including formulas based on paraxial ray-tracing (Barrett and Olsen) and based...

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...

Detection of SO tendon abnormality versus atrophy

This study aimed to evaluate patterns of binocular misalignment in primary gaze, lateral and vertical gaze, and head tilt in patients showing head-tilt dependent hypertropia associated with discontinued superior oblique (SO) tendon but without SO muscle atrophy, versus patients with...

Bilateral versus unilateral recession outcomes for intermittent exotropia

The aim of this study was to compare surgical motor and sensory outcomes of unilateral versus bilateral lateral rectus recessions in children with small angle intermittent exotropia. This was a retrospective study of 55 patients; 28 bilateral and 27 unilateral...

Prognosis prediction using clinical findings for fourth nerve palsies

The authors present a retrospective review of a cohort of patients diagnosed with fourth cranial nerve palsy with more than six months follow-up, over a 10-year period at a single centre. Thirty-five patients were included in the study, and spilt...

Single case report of horizontal gaze paresis due to medial pontine haemorrhage

The authors report a single case (80-year-old female) of bilateral horizontal conjugate gaze palsy due to a dorsal median pontine haemorrhage. The patient presented with skew deviation, bilateral horizontal conjugate gaze palsy, vertical gaze palsy, ipsilateral lower motor neuron facial...

Natural history of optic nerve head drusen in a paediatric population

A retrospective case notes review is presented focusing on children diagnosed with optic nerve head drusen over an eight-year period. Inclusion criteria included cases coded for optic nerve head drusen and / or pseudopapilledema. The aim of the study was...

Use of control scores for intermittent exotropia

This study surveyed paediatric ophthalmologists to determine their use of the Newcastle, PEDIG and LACTOSE control scores in the diagnosis and management of intermittent exotropia. The authors aimed to identify how frequently control scores are used clinically, the barriers to...

OCTA optic disc measurement differences between glaucoma and pituitary macroadenoma

This prospective case-control study aimed to assess the potential of optical coherence tomography (OCT) and OCT angiography (OCTA) in distinguishing between glaucoma and pituitary macroadenoma based on optic disc appearance. Thirty-one patients (23 with glaucoma, eight with pituitary macroadenoma) were...

Risk factors and management for postoperative complications in strabismus surgery

This retrospective cohort study examined 1273 patients, comprising 1035 cases of exotropia and 238 cases of esotropia, with a minimum 18-month follow-up after strabismus surgery. Baseline demographics, age at surgery, pre / postoperative visual acuity, and deviation were included. Complications...

RCT of unilateral vs bilateral surgery for lateral incomitance in exotropia

The purpose of this study was to evaluate and compare the surgical outcomes in the management of lateral incomitance with regard to ocular alignment and change in lateral incomitance in cases of bilateral vs. unilateral strabismus surgery. This was a...

Potential gender and degree of deviation bias regarding perceived urgency for surgery

This study aimed to define potential factors that influence the perceived urgency of strabismus surgery by ophthalmologists. This was a survey study which comprised questions regarding demographics of the ophthalmology respondents and a ranking of eight photos of adults with...
