Somatostatin protects retinal pericytes

Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...

Comparison of bupivacaine injection vs. mini-tenotomy for small angle deviations

Bupivacaine hydrochloride is an aminoacyltype local anaesthetic. Injection into extraocular muscles elicits a myotoxic response destroying striated muscle fibres but sparing satellite cells, nerves and vessels. Preserved satellite cells proliferate to form new muscle fibres, causing muscle hypertrophy and greater...

The most frequent complaints and claims in ophthalmology – a Medical Protection Society (MPS) analysis

The authors look at the reasons behind medico-legal cases reported to MPS and share key learning points. Complications following ophthalmology surgery are rare, however, medico-legal cases are not uncommon due to the significant impact they can have on patients’ lifestyles....

Screening for Sickle Cell Retinopathy (SCR): Why we do wide-field imaging, OCT/OCT-A for SCR – Newcastle upon Tyne Hospitals NHS Foundation Trust

I have been working in ophthalmology for over five years as a photographer and research co-ordinator, and it is fascinating, rewarding, and interesting to learn all about the different diseases associated with the eye. One condition that has been a...

Twenty-five years in retina

In the next of our articles celebrating 25 years of Eye News, the authors look at how the retina specialty has changed over this time and ask what the future might hold. Retinal disease management has benefited from great advances...

Discussing treatment modalities for bilateral wet AMD

A 65-year-old lady with bilateral wet AMD and vision of 6/24 comes with an internet search about current therapies. How do you explain the various treatment modalities available? There are two NICE approved treatments for wet age-related macular degeneration (AMD)....

The management of antiplatelets and anticoagulation in elective ophthalmic surgery

Clinical scenario: A 57-year-old gentleman who is scheduled to have Mohs micrographic surgery and reconstruction for a medial canthal basel cell carcinoma (BCC) has been started on aspirin and clopidogrel following a coronary stent three weeks ago. Does the antiplatelet...

The Preston Rule

The selection, specification and fitting of a spectacle frame necessitates the recording of certain measurements particular to the frame. These measurements are also essential when it is required to manufacture a handmade spectacle frame. Instruments designed to accomplish this task...

My top five: Emerging alternatives to manage and treat nAMD

Wet (exudative or neovascular) age-related macular degeneration (AMD) is characterised by choroidal neovascularisation, in which new blood vessels from the choroid invade through Bruch’s membrane. These blood vessels proliferate beneath or through the retinal pigment epithelium (RPE), causing patients to...

Postop esotropia re-drift

The authors aimed to investigate the rate and onset of development of re-drift after infantile esotropia surgery and identify factors associated with this. This was a retrospective study of 112 patients with a mean postoperative follow-up of 9.5 years. Consecutive...

A case of late spontaneous subluxation of in-the-bag intraocular implant

An 82-year-old frail lady was referred by her optometrist with a finding of subluxated implant in the right eye. She had uneventful phacoemulcification with in-the-bag intraocular implant 17 years earlier. There is no history of having had pseudoexfoliation (PXF) or...

A comparison of light sources in retinal imaging

Before starting to talk about the light sources present in retinal imaging, it is necessary to start from the base: the light. Light is an electromagnetic wave whose smallest part is the photon (or quantum of light). A high frequency...
