Accuracy of intraocular lens power calculations in paediatric eyes

A study comparing the accuracy of the SRK II, SRK/T, Hoffer Q, Holladay 1, T2 and Super formula in predictive refractive outcomes in children undergoing primary IOL insertion into the capsular bag following cataract surgery. A total of 377 eyes...

Practical application of cataract risk stratification

This study assessed the practicability of a risk stratification system, the New Zealand Cataract Risk Stratification (NZCRS) in a major teaching hospital. The scoring system was as follows: three points for Dense cataract, pseudoexfoliation (PXF), phacodonesis, previous vitrectomy and only...

Visual field progression after glaucoma drainage device implantation

This retrospective interventional case series assessed changes to visual fields after implantation of a glaucoma drainage device (Baerveldt, Ahmed or Molteno Devices) between 2010 and 2015. A total of 106 eyes from 96 patients were included in the final analysis...

Investigating MOG-IgG as a cause for optic perineuritis

Optic perineuritis can be a manifestation of infectious and systemic inflammatory disorders, but in most cases is considered idiopathic. Diagnosis is established by magnetic resonance imaging (MRI) with the demonstration of optic nerve sheath enhancement with sparing of the optic...

Examination of optic disc drusen using computer-based fundus analysis

This case-control study analysed the optic disc angioarchitecture in optic disc drusen (ODD) using computer-based fundus examination. A group of ODD patients were compared to a group of healthy controls with normal optic discs. The cohort included 30 healthy volunteers...

A novel presentation of optic disc oedema with syphilis

Optic disc oedema (ODE) due to syphilis without visual compromise has been primarily attributed to papilloedema from raised intracranial pressure or optic perineuritis from optic nerve sheath inflammation. These terms were proposed before magnetic resonance imaging (MRI) was largely available....

Mechanism of colour vision involvement in multiple sclerosis

There is evidence to show that the optic nerve and retina are affected in multiple sclerosis (MS) even without any clinical evidence or history of optic neuritis (ON). MS without optic neuritis causes colour-vision deficit, however, the evidence for selective...

Using small amplitude saccades to assess saccadic velocity

Saccades are a key component in the assessment and diagnosis of neuro-ophthalmological disorders. Clinicians are typically taught to use large amplitude saccades (LAS) of at least 20 degrees to assess saccadic velocity. It has been suggested, however, that small amplitude...

Saccadic eye movements in young-onset Parkinson’s disease

The objective of this study was to understand control of saccadic eye movements in patients with young onset Parkinson’s disease (YOPD) where onset of disease symptoms appears early in life (<40 years of age). Functional magnetic resonance imaging (fMRI) was...

Ocular adnexal marginal zone b-cell lymphoma

This is a multicentre retrospective study of seven eye centres of 689 patients with ocular adnexal extranodal marginal zone b-cell lymphoma (OA-EMZL). The median follow-up time was 42 months and the median age was 62 years. Fifty-five percent were women;...

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...

Surgical results in spinocerebellar ataxia (SCA)

Patients with SCA frequently develop ocular motility abnormalities including nystagmus, abnormal smooth pursuits, dysmetric saccades, divergence paresis and ophthalmoplegia. Incidence of diplopia is higher in SCA type 3. The purpose of this study was to evaluate surgical responses and outcomes...
