IgG4-related disease or Graves orbitopathy

This is retrospective review of patients who had been diagnosed with both IgG4-related ophthalmic disease (IgG4-ROD) and Graves orbitopathy over a four year period. Eight patients were identified. The diagnosis of IgG4-ROD was based on 10 or more IgG4+ plasma...

Duane’s retraction syndrome (DRS)

The authors aimed to review all cases of DRS presenting to a tertiary paediatric eye clinic in South Africa during a 20-year period. This was a retrospective study in Cape Town involving 120 patents (80 mixed race, 24 black and...

How to reconstruct an upper lid defect

In this 10-year review, the authors look at published techniques for repairing upper lid defects and their respective success. Of the 10 studies included in this paper, they divide the techniques described within to bridging and non-bridging. Bridging techniques tend...

Closed-chamber haptic re-externalisation for posteriorly displaced sclerotomy and inadequate haptic tuck in glued posterior chamber intraocular lenses

This technique (online video http://jcrsjournal.org) emphasises the importance of both symmetrical and sufficient anterior placement of sclerotomies to externalise an adequate length of the haptics, which in turn provides good centration and stability of the intra-ocular lens (IOL). The authors...

William’s syndrome

William’s syndrome is a congenital multisystem disorder involving the cardiovascular, connective tissue and central nervous systems. The aim of this study was to evaluate the frequency and severity of ophthalmic manifestations and associated diseases as well as provide epidemiology data...

Two bifocals and a trifocal

The authors compare the optical outcomes of two bifocal intraocular lenses (AcrySof ReSTOR +2.50 Diopter [D] add +3.0D add) with a trifocal lens (AT LISA tri 839MP). The optical qualities of the lenses were quantified by measuring the modulation transfer...

Distance esotropia due to excessive near work

The authors aimed to review cases with divergence insufficiency esotropia in 12 young adults associated with excessive near work. Patients were aged 28.17 ±4.06 years and had normal external, anterior / posterior segment examinations and no neurological signs. Ten had...

Cutting-edge practice in glaucoma care: what, how and why?

More effective treatments and drug delivery modalities, implantable minimally invasive glaucoma surgical (MIGS) devices, as well as accelerating clinical research programmes, will transform the surgical and clinical management of glaucoma in the near future. There is also an ever-greater emphasis...

Using graphical illustration to predict giant cell arteritis

A nomogram is a chart or graph of scaled variables that facilitates the approximate computation of a mathematical function via intersecting lines. The objective of this study was to illustrate the use of a nomogram for the prediction of giant...

Effects of phacoemulsification on IOP and drug use in glaucoma

For patients with comorbid cataract and primary open-angle glaucoma (POAG), guidance is lacking as to whether cataract extraction and traditional filtering surgery should be performed as a staged or combined procedure. Achieving this guidance requires an evidence-based understanding of the...

Factors associated with inferior oblique transposition surgery and occurrence of anti-elevation syndrome

The purpose of this study was to correlate the frequency of anti-elevation syndrome (AES) with the magnitude of the anterior transposition of the inferior oblique. This was a retrospective study of 312 eyes of 170 patients. Mean age at surgery...

Cataract extraction and microperimetry

In this study, the authors assessed retinal sensitivity before and after cataract extraction, in an effort to understand how lens opacities may affect microperimetry results in glaucoma and macular diseases. Thirty patients awaiting cataract extraction were examined and their lens...
