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...

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...

AC/A measurement differences

The authors sought to investigate differences in stimulus accommodative convergence/accommodation (AC/A) ratio using various techniques and accommodative stimuli. The study included 81 orthoptic students; 15 males and 66 females with a mean age of 21 years ±1. Ocular deviation was...

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...

Impact of preop occlusion on surgical outcome

The purpose of this study was to evaluate the effect of improved control with part-time occlusion treatment on the final postoperative surgical outcome in patients with intermittent exotropia. Eighty-nine patients were recruited who had unilateral lateral rectus recess / reset...

IO over action surgery

This study aimed to compare the effectiveness of the two surgical methods on the correction of inferior oblique over action (IOOA). This was a retrospective study of 99 eyes of 56 patients; 47 myectomy and 52 anterior transposition procedures. Mean...

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...

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...
