Using MRI to assess normal variation in optic chiasm anatomy

The authors present an MRI study including 61 MRI scans using a 1.5 T with slice thickness of 1 or 5mm and the sequence showing the highest resolution of the chiasm. A predetermined set of measurements were taken in a...

Uveitis ocular toxoplasmosis

This is a retrospective study of 106 patients between March 2011 and June 2018, of 37 IgM +group and 69 IgM - group of patients. The clinical features, demographics of patients with ocular toxoplasmosis (OT) were studied according to the...

Accuracy of AS-OCT muscle insertion measurements

Anterior segment - optical coherence tomography (AS-OCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of AS-OCT for locating horizontal extraocular muscle insertions after strabismus surgery...

Accuracy of ASOCT muscle insertion measurements

Anterior segment optical coherence tomography (ASOCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of ASOCT for locating horizontal extraocular muscle insertions after strabismus surgery in...

Using optical coherence tomography angiography to detect MoyaMoya vasculopathy

Moyamoya (MM) disease is a chronic cerebrovascular disease that can lead to progressive stenosis of the terminal portions of the internal carotid arteries and their proximal branches. The authors carried out a cross-sectional cohort study to investigate vascular changes in...

Pilot trial of virtual reality to treat amblyopia beyond the age of seven years

A pilot double-blind randomised controlled trial is presented. Patients were required to be between seven and 38 years of age, have a diagnosis of anisometropic and / or strabismus unilateral amblyopia, visual acuity in the amblyopic eye between 0.3-1.0 LogMAR...

Test combination which could detect prodromal Alzheimer disease

The authors prospectively recruited a convenience sample of individuals aged over 65 and either with a diagnosis of mild cognitive impairment (MCI) due to Alzheimer disease or normal cognition. Other types of dementia and severe neurological conditions were excluded. All...

Exotropic angle by PACT vs under translucent cover

The authors aimed to validate the photographic analysis with a translucent cover by comparing the results obtained from this analysis with the angle obtained by prism cover test (PACT) in patients with intermittent exotropia. This was a retrospective review of...

Proof of concept for using aqueous humour to detect retinoblastoma variant

A proof of concept study is presented with the aim of assessing the feasibility of using aqueous humour surrogate marker for tumour tissue for identifying retinoblastoma RB1 variant. Three children undergoing enucleation for retinoblastoma were recruited from a single centre....

Comparison of nylon versus polyglactin sutures

The purpose of this study was to compare postoperative complications between incision closure by nylon suture and polyglactin suture in paediatric cataract surgery. This was a prospective single-centre non-randomised study of 82 eyes (41 children) with median age of four...

Effect of heredity on risk of diabetic retinopathy

This study used survival analysis on 2199 patients who had reached vision-threatening diabetic retinopathy to investigate the contribution of heredity to diabetes together with other known risk factors for the development of either proliferative diabetic retinopathy (PDR) or diabetic macular...
