Mediation of vertical vergence

The authors hypothesised that if vertical vergence were mediated by vertical rectus muscles, then the eye that moves during a vertical fusion task would produce larger vertical vergence when abducted versus adducted. Similarly, if mediated by the oblique muscles then...

Pupil responses in diabetes

This study aimed to investigate pupillary involvement in patients with type 2 diabetes mellitus (DM) and to evaluate any relationship between severity of diabetic retinopathy (DR) and pupillary responses. Participants included 133 individuals in four groups: proliferative DR (n=21), non-proliferative...

Migraine attack: does retinal and peripapillary blood flow change?

This prospective clinical study compared retinal and peripapillary blood flow parameters in migraine patients during an attack with healthy controls using optical coherence tomography angiography (OCTA). OCTAs were performed on 52 eyes from 26 migraine sufferers and 48 eyes from...

Measurement considerations in OCT results with suspected glaucoma

The purpose of this study was to determine retinal nerve fibre (RNFL) thickness parameters and assess the relationship between the cup-to-disc (CD) ratio and RNFL measurements of paediatric patients who had optic nerve appearance suspicious for glaucoma based on enlarged...

BEST stereotest

BEST (Bernell Evaluation of Stereopsis Test) is a filter-free method that uses lenticular technology. The test presents colourful animal targets ranging from 400 to 40”. Stereoacuity was measured with BEST and Randot in 100 children aged 3.3-17.8 years, mean 8.52...

Normal reference values for the RETeval device

The purpose of this study was to provide normative data of full-field electroretinography (ERG) responses in the paediatric population using the RETeval device in healthy children with normal retinas. This was a prospective study of 38 eyes of 20 patients...

A case presentation of morning glory disc anomaly and peripapillary staphyloma

The purpose of this paper is to present a case of an 18-month-old girl initially presenting with strabismus. Fixation of the affected eye was intermittent with a relative afferent pupillary defect. A fundus photography of the affected left eye showed...

Suture versus sutureless paediatric cataract surgery

This was a prospective study comparing the outcomes, feasibility and safety of clear corneal cataract surgery with or without sutures in children with paediatric cataract. There were 85 eyes in each group (170 eyes of 110 patients). Each eye was...

Effect of one versus 24 hours diagnostic occlusion

The purpose of this study was to compare measurements taken after one and 24 hours of diagnostic occlusion in cases of basic and divergence excess types of intermittent exotropia. This was a prospective study of 43 patients (34 females) with...

Surgically induced astigmatism after cataract surgery

In this study, the authors analysed a dataset of 122 eyes of 122 patients with pre- and postoperative measurements of corneal astigmatism with IOL Master 700. A standardised 2.5mm superior corneal incision was utilised. The corneal power vector component in...

Could midbrain volume on MRI be used to guide diagnosis of progressive supranuclear palsy?

The authors present a cohort study, of patients with a likely diagnosis of progressive supranuclear palsy (PSP) using a combination of prospective assessment and retrospective review. The cohort comprised of 14 patients; the data for six patients was obtained through...

Surgical technique combining vertical transposition and horizontal plication for mixed deviations

A retrospective case series, assessed adult cases with horizontal and vertical strabismus who had undergone unilateral vertical transposition of the horizontal rectus muscles during a recession-plication over a three-year period. A single surgeon performed all 15 procedures. Postoperative measurements were...
