Using a pupillometer to confirm presence of RAPD in post stroke homonymous hemianopia

It has been reported that relative afferent pupillary defects (RAPDs) may be present in patients with occipital lobe lesions. However, a small contralateral RAPD due to a difference in the crossed and uncrossed fibres can be difficult to detect using...

Use of the RAPDx device to evaluate efficacy of treatment in patients with optic nerve disease

The RAPDx objectively determines the RAPD magnitude by alternately presenting light stimuli to each eye and deriving amplitude and latency scores. The authors of this paper evaluated the amplitude and latency scores from the RAPDx together with other ophthalmic investigations...

Clinical and neuro-ophthalmologic predictors of visual outcome in idiopathic intracranial hypertension

This prospective study of 40 patients aims to assess visual morbidity in patients with idiopathic intracranial hypertension (IIH). Final visual outcome of patients was compared with clinical and neuro-ophthalmic parameters such as visual acuity, visual field, contrast sensitivity, retinal nerve...

Diagnosis of amiodarone-associated optic neuropathy

Amiodarone is a widely used anti-arrhythmic drug. Several case reports describe optic neuropathy which has been linked to its use. This case series discusses the diagnosis of amiodarone-associated optic neuropathy (AAON) and its potential impact on cardiac therapy. The authors...

An atypical presentation of Vogt-Koyanagi-Harada Disease

The authors present a single case of atypical presentation of Vogt-Koyanagi-Harada disease. A 42-year-old female presented with unilateral visual loss associated with systemic symptoms of fever and headache. Initial ophthalmic examination revealed a unilateral neuroretinitis, however, investigations for infectious and...

Overview of traumatic optic neuropathy

The authors present the clinical features and role of various treatment modalities on the final vision outcome in traumatic optic neuropathy (TON). They retrospectively reviewed the records of patients with a diagnosis of TON over a four year period in...

A case of post-viral ocular microflutter

A number of eye movements disrupt visual fixation, one such movement being saccadic intrusions which are described as small involuntary saccadic movements. Among saccadic intrusions without intersaccadic intervals, ocular flutter and opsoclonus are prominent. When the saccadic amplitude is very...

Optic disc haemorrhages as a risk factor for poor outcomes in IIH

This is a report of a review of optic disc photographs, of the type and frequency of the optic disc haemorrhages (ODH), papilloedema grades and other fundoscopic abnormalities at baseline. In the study eyes of 133 patients enrolled in the...

Use of acetazolamide for symptoms of visual vertigo

Visual vertigo is a disorder characterised by symptoms of dizziness, vertigo, unsteadiness, disorientation and general discomfort induced by visual triggers. It is currently treated with vestibular rehabilitation therapy, with no effective pharmacotherapy options available for treatment resistant case. Oral acetazolamide...

A case report of alternating anisocoria with associated nasal congestion

The authors have described a group of healthy individuals who show alternating anisocoria, in a previous paper. In these cases, the pupil asymmetry alternates between eyes every few hours, with no observed instances when both pupils are equal in size....

Could medical cannabis be used to successfully treat blepharospam?

This study observed the effect of medical cannabis in benign essential blepharospasm (BEB), in addition to standard botulinum toxin treatment. The study comprised of a retrospective chart review on eligible patients and included information on patient demographics, responses, cannabis history...

Development of testing protocols for high and low contrast visual acuity

Dysfunction of the afferent visual system, characterised by impairments in high-contrast visual acuity (HCVA) and low-contrast visual acuity (LCVA) have been demonstrated in some neurological conditions such as multiple sclerosis and Parkinson’s disease. HCVA and LCVA are also potential quantitative...
