How good does my vision have to be to drive this thing? Visual standards for various occupations

We can all picture that moment in clinic: you are about to tell someone that they’re no longer legally able to drive, ready to deploy our ‘breaking bad news’ techniques. For some patients this may have been expected, or they...

Clinical Techniques in Ophthalmology

Ophthalmology is a highly specialised field with complex equipment often unfamiliar to medical students and foundation doctors due to limited exposure during training. Clinical Techniques in Ophthalmology is a 300-page handbook divided into six sections: Basic Clinical Optics, Ophthalmic Equipment,...

Self refracting – child’s play?

Uncorrected refractive error was the leading cause of vision impairment in the world in 2010. Although refractive error may be safely and effectively corrected with spectacles, lack of well-trained refractionists in settings of limited resources may be a major barrier....

Unexplained vision loss following exposure to combat

Non-organic vision loss (NOVL) is defined as a decrease in visual acuity or visual field without an identifiable organic cause. NOVL can be particularly challenging and time-consuming to diagnose, especially where the vision loss is superimposed on an element of...

Femto-DMEK – a solution for high re-bubbling rates?

This retrospective study examined results of patients that underwent femtosecond laser enabled descemet membrane endothelial keratoplasty (DMEK) (FE-DMEK) and manual DMEK (M-DMEK) for Fuch’s endothelial dystrophy. In FE-DMEK femtosecond laser was used to create 8.25mm descemetorhexis, whereas during M-DMEK- descemetorhexis...

Stromal cell alignment in damaged cornea

Stromal keratocytes are responsible for wound healing in the cornea following damage. Keratocytes at the site of injury become activated and differentiate to myofibroblasts which secrete extracellular matrix (ECM) to close the wound, a response mediated by transforming growth factor...

Finasteride and central serous chorioretinopathy

The pathophysiology of central serous chorioretinopathy (CSC) is complex and has not been fully elucidated. Suggested theories include hyperpermeability and increased hydrostatic pressure in the choroidal vasculature, which creates RPE detachments overwhelming the RPE barrier function, leading to accumulation of...

Quarter DMEK

This case report describes a novel technique where one quarter of Descemet’s membrane (DM) was transplanted during a quarter-descemet membrane endothelial keratoplasty (DMEK) procedure. DMEK graft was prepared from a 58-year-old corneo-scleral donor after one week in culture. Peripheral DM...

Wrong intraocular lens events – what lessons have we learned?

Data from wrong IOL patient safety incidents (PSIs) submitted to the National Reporting and Learning System (2010–2014) were reviewed and scrutinised by thematic analysis and compared with the historical data collected for groups in 2003-2010, prior to the mandatory checklist...

Oral azithromycin for meibomian gland disease

Oral tetracyclines have been the traditional systemic treatment of blepharitis and acne rosacea, through inhibiting bacterial lipase production and reducing fatty acids. However, tetracyclines have a number of adverse side-effects and are required to be taken for a long duration...

Boston type I keratoprosthesis for limbal stem cell deficiency

Boston type I keratoprosthesis (KPro) long-term outcomes were compared in patients with and without limbal stem cell deficiency (LSCD) in this retrospective study. In the 11 year period 68 procedures were performed in individuals with LSCD, and 105 procedures in...
