Binocular summation with low contrast

The magnitude of binocular summation was investigated in normal control subjects using four different letter charts of varying type with fixed and variable contrast levels and spatial frequency to determine which tests most readily reveal binocular summation in normal subjects....

Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure

The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...

Long-term retinal changes following unilateral retrobulbar optic neuritis

The aim of this study was to assess the longitudinal changes in retinal nerve fibre layer (RNFL) thickness after a first attack of optic neuritis and to investigate the impact of treatment on RNFL thinning at one year after the...

Atropine penalisation for amblyopia in the UK

The authors aimed to determine the current clinical practice of atropine penalisation (AP) in the UK, to identify perceived barriers limiting use of AP as a first line treatment and ascertain whether any of the barriers could be resolved. An...

Fixation disparity measurement

The authors evaluate different procedures looking at point zero, fixation disparity (FD) and motor fusion amplitude in order to calibrate the measurement of FD with Ogle’s apparatus with the overall goal to create a standardised measurement of the FD curve...

Orthoptic Cochrane reviews

The purpose of this study was to explore the Cochrane Eyes and Vision (CEV) library to extract and overview protocols and systematic reviews of relevance to orthoptic practice. A full database search was made of the 2016 library. Twenty-seven systematic...

Risk factors for NTG in a young Korean population

Previously known ocular and systemic risk factors for normal tension glaucoma (NTG) include myopia, peripapillary atrophy, disc haemorrhage, migraine, obstructive sleep apnoea, thyroid disease and cerebral infarction. However, most NTG risk factor studies have examined patients aged 40 years and...

Brn3b neuroprotective effect in rat glaucoma model

An adeno-associated virus-directed overexpression of the Brn3b protein in hypothesised to confer neuroprotective effects in this paper. This is ultimately tested in a well-accepted rat glaucoma model (Morrison’s model: saline injection into episcleral veins of rat eyes with a force...

Rare case reports of benign optic glioma in adults with clinically aggressive nature

Primary optic nerve gliomas are most commonly benign and occurring in childhood. Malignant optic gliomas occur in adulthood and follow an aggressive course usually leading to blindness and death within months. This paper describes the clinical and histopathological features of...

Adolescent optic disc haemorrhages

The authors conducted this study to describe the clinical characteristics of multi-layered optic disc haemorrhages in adolescents. This was a retrospective review of 16 eyes (11 right and five left) of 16 patients with a mean age of 15 ±2.6...

Nasolacrimal duct screening to minimise post cataract endophthalmitis

This case control study compared the nasolacrimal duct (NLD) patency in a random sample of phacoemulsification cataract surgery patients (control group) versus a consecutive series of patients who developed endophthalmitis post cataract surgery (case group). NLD syringing was performed in...

Precision and accuracy of TearLab osmometer

Measuring tear osmolarity has been identified as a potential method for objectively diagnosing dry eye. TearLab osmolarity system is an in situ osmometer which may be a promising candidate for clinical use as it is portable and only requires a...
