Observational Study
Retrobulbar anaesthesia for adjustable strabismus surgery in adults: a prospective observational study.
To characterize the ocular response to retrobulbar anaesthesia and to evaluate the efficacy of retrobulbar anaesthesia for adjustable strabismus surgery in adults. ⋯ Retrobulbar anaesthesia in the context of adult, adjustable strabismus surgery is a relatively safe and effective technique. It provides excellent intraoperative analgesia and akinesia. Retrobulbar anaesthesia enables for same-day suture adjustments to be reliably performed.

To assess recent high-risk ophthalmic medical device recalls. ⋯ Class I recalls surrounding ophthalmology are relatively infrequent compared to other medical specialties. However, given the impact of Class I recalls in the field, ophthalmologists have an impetus to advocate for stronger device regulation particularly in the context of post-marketing surveillance.

Previous studies have suggested an association between dry eye and migraine. In a busy ophthalmologist clinic, quick identification of dry eye in migraine sufferers may improve their quality of life. Tear osmolarity is an objective and reliable tool for diagnosing dry eye. It has not been investigated in any population with migraine. Using tear osmolarity and questionnaires, we aimed to explore the relationship between dry eye and clinical symptoms in patients with migraine. ⋯ Patients with migraine, especially those with aura, appear more likely to have dry eye, as indicated by tear osmolarity. Tear osmolarity may also be greater in those who suffer from daily headaches.

Observational Study
Test characteristics of point-of-care ultrasonography for the diagnosis of acute posterior ocular pathology.
The objective of this study was to determine the test characteristics of point-of-care ultrasonography (POCUS) for the diagnosis of retinal tear (RT), retinal detachment (RD), posterior vitreous detachment (PVD), and vitreous hemorrhage (VH). ⋯ Ocular POCUS detected all RDs but has limited use for the diagnosis of RTs. Patients with suspected acute ocular posterior pathology should be referred to ophthalmology independent of ocular POCUS.
