The impact of obstructive sleep apnoea monitoring functionality on smartwatches: a new frontier for ophthalmologists
Dawn of a new era in wearable technology? Smartwatches have really stepped up their game and have evolved from telling time to keeping an eye on our health. In February 2024, the United States Food and Drug Administration (FDA) gave...The eye surgeon and eye physician together: the joint ophthalmic clinic
Since the early 19th century, physicians and surgeons have been working together in eye clinics and hospitals to bring about the best outcome for the patients. From the early Babylonian age, important advances in ophthalmic knowledge arose in a stuttered...The results of the last survey Feb25
*Please be aware that this data does not form part of a peer reviewed research study. The information therein should not be relied upon for clinical purposes but instead used as a guide for clinical practice and reflection. The sample...
Science maps to outline emerging topics in strabismus
Science maps show the current status of research in a specific field – a form of scientometrics. Co-word analysis is an example of graphic modelling in which keywords are used to study the conceptual structure of a research field. In...
Effects of topical anaesthetic on intraocular pressure
This prospective interventional study assessed the effects of repeated intraocular pressure (IOP) using Goldmann applanation tonometry and applanation resonance tonometry in six volunteers. Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...
Effects of blood donation on the physiology of the eye
Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...
MicroRNA inhibits corneal neovascularisation
MicroRNAs (miR) are small non-coding RNA that target mRNA for destruction. MiR target about 30% of the protein coding genes and fine tune their expression. MiR have been shown to be involved in several cellular processes including cell cycle, tissue...
Ranibizumab safety in pregnancy
Vascular endothelial growth factor (VEGF) plays a pivotal role during pregnancy, and systemic anti-VEGF administration during this period should thus be avoided. VEGF is expressed in multiple embryonic and foetal tissues during development, with the highest levels found in the...
Mast cells in Graves’ ophthalmopathy
Graves’ ophthalmopathy (GO) is a potentially sight-threatening ocular disease, occurring in patients with hyperthyroidism due to Graves’ disease. Also known as thyroid-associated ophthalmopathy, GO is characterised by orbital infiltration by immune cells including macrophages, T cells and plasma cells, which...Ciclosporin and dry eye
Dry eye has an estimated prevalence of between 5 and 50% worldwide and has physical, psychological and socioeconomic consequences for the human population [1]. Loss of tear film homeostasis with associated ocular surface inflammation causes symptoms ranging from ‘tired’ eyes...Ophthalmic learning through the lens of cognitivism and constructivism
Learning in ophthalmology is multi-faceted, from understanding the fundamentals of eye anatomy and physiology to higher order skills such as performing cataract and vitreoretinal surgery. Having a strong foundation in the basics is a necessity for higher order knowledge synthesis,...
