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...

AI-Based devices in national screening programmes: barriers and challenges

Diabetic retinopathy (DR) may have long-term complications and is recorded as a leading cause of blindness. National DR screening programmes have effectively reduced severe visual loss by timely detection and subsequent treatment of sight-threatening proliferative DR and diabetic macular oedema....

Nano-ophthalmology paves a new path in the future of eyecare

Introduction The treatments of ocular conditions in the field of ophthalmology varies from topical to surgical procedures. The field of nanotechnology is one of the fast-growing fields of medicine, which plays an important role in turning the impossibilities of the...

Oral proton pump inhibitors in macular degeneration patients

The authors report five patients with advanced wet macular degeneration and poor vision with onset or enhancement of visual hallucinations with the use of proton pump inhibitors for heartburn management. The hallucinations were reversible with discontinuation of medication. The authors...

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...

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...

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...
