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...

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...

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...

Surgery for lost inferior rectus muscle

This prospective study evaluated the impact of simultaneous ipsilateral superior rectus (SR) recession and superior rectus (IO) anterior transposition on the primary position alignment in six patients with traumatic loss of the inferior rectus (IR) muscle. Five males and one...

A case of ipsilateral fourth nerve paresis and Horner’s syndrome

The author presents a single case report of an exceptional association between fourth nerve palsy and ipsilateral Horner’s Syndrome. The case is presented alongside magnetic resonance images (MRI) which reveal a mass in the right cavernous sinus. The 54-year-old woman...

Surgery for superior oblique palsy with superior rectus contracture

With limited information in the literature regarding simultaneous surgery in cases with superior rectus (SR) contracture in superior oblique (SO) palsy, the authors aimed to evaluate the efficacy of combined SR/IO surgery. This was a retrospective study of 15 cases...

LACTOSE control score for exotropia

The purpose of this study was to determine the extent of change in control over multiple measurements in a single clinic visit using the Look and Cover, then Ten seconds of Observation Scale for Exotropia (LACTOSE) scoring system in patients...

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....

Augmented surgery for monocular elevation deficiency

The outcomes are described for augmented lateral rectus superior transposition in cases of acquired monocular elevation deficiency (MED) associated with large hypotropia in primary gaze. The lateral rectus was transposed superiorly and reinserted on sclera between the temporal margin of...

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...

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...
