Visual retraining for homonymous hemianopia following stroke

This is a clinical trial evaluating the efficacy of motion discrimination training as a potential therapy for stroke-induced hemianopic visual field defects involving 48 patients. They were randomised into two arms, one intervention (deficit-field) and one control (sighted-field). Patients were...

Whiteboard illustrations added to pre-surgery timeout procedure

The authors present results of a quality improvement initiative. A whiteboard illustrated with right and left eyes with views of the extraocular muscles was developed, the board also contained spaces for the patient’s name, deviation, versions and the procedure name....

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...

Surgical technique for small-angle hypertropia

In order to treat small-angle hypertropia of <5PF associated with mild / moderate upshoot in adduction, an option is to suture the inferior oblique (IO) belly to the sclera following its natural muscle direction or with anterior transposition. This study...

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...

Long-term improvement of stereopsis in intermittent refractive esotropia

This was a retrospective study to review the records of patients with refractive accommodative esotropia (RAET) to determine long-term stereoacuity (SA) improvement in those that showed initial poor or no stereopsis. The study included 79 patients; 54% male and mean...

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...

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...
