Hess vs. Harms vs. PCT measurements

This study aimed to compare the results of the different tests in 36 strabismus patients and 18 healthy controls aged 6-81 years. Tests included alternate prism cover test, Hess screen and Harms screen. Because of glasses restrictions with the Harms...

Outcomes for symptomatic esophoria with or without prism adaptation test

The authors aimed to compare the frequency of repeated interventions between patients who had prism adaptation test (PAT) and conventional orthoptic measurements, and those that did not, in order to measure changes in angle after PAT and surgical outcome. This...

Static subjective visual vertical (SVV) in the normal visual system

Graviception is the perception of a persons’ orientation relative to gravitational force. This can be measured by means of subjective verticals, which can be divided into three tests: subjective visual vertical (SVV), subjective postural vertical (SPV) and subjective haptic vertical...

Detecting glaucoma with only OCT

In this review article, the authors describe a probability model based upon only OCT to detect glaucoma. They explain how normal anatomical variation can lead to false positives and applying a model to account for this improves specificity. The application...

Autophagy in lens mitochondria loss

The lens consists of a monolayer of epithelial cells that overlies fibre cells that differentiate from epithelial cells at the equator. While developing, fibre cells need mitochondria to provide energy, as they mature they lose these and other organelles to...

Local surgical treatment of trigeminal neuralgia

This is a retrospective review of a new surgical treatment of intractable periorbital neuropathic pain. Five patients with post-herpetic (three), post-traumatic (one) and idiopathic (one) neuralgia underwent transection of the nerves supplying the dermatomes affected by the neuropathic pain. The...

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....

Effect of postoperative swelling on lid surgery outcomes

This is a review of patients undergoing upper lid external levator resection ptosis surgery or blepharoplasty, to assess whether the degree of early postoperative swelling affects the final lid position. Twenty-five patients undergoing ptosis surgery and 29 upper lid blepharoplasty...

Insights on medical AI for ophthalmology: an update on current perspectives

Artificial intelligence (AI) has immense promise for revolutionising medical practice. Generative AI is a form of AI in which algorithms are trained on datasets that can be used to generate new content, such as text, images or video based on...

Resection versus plication impact on conjunctival-scleral thickness

In this study the authors aimed to compare the conjunctival-scleral thickness as measured with anterior segment (AS) OCT before and after medial rectus muscle resection or plication for exotropia. This was a prospective study of 7 resection cases and nine...

MacuMira and Keeler announce strategic partnership to expand dry AMD therapy

Keeler, a global leader in ophthalmic innovation with more than a century of heritage, and MacuMira Medical Devices Inc, a pioneering Canadian company, has announced a strategic partnership. Under the agreement, Keeler will manufacture the MacuMira device and lead its...

Learning from litigation: ocular drug toxicity

Being the subject of litigation is stressful and upsetting. Having to look back over your previous decisions and justify the care you delivered in good faith can be difficult. Sadly, we all live with the sword of Damocles above us...
