History A 35-year-old female presented to the emergency eye clinic with an acutely red, painful, photophobic left eye. She was a contact lens-wearer but denied swimming, showering, or sleeping in her lenses. She resided on a farm and worked as...
Reduced blood flow and age-related macular degeneration
This was a prospective cross-sectional study assessing changes in blood flow velocity in patients with age-related macular degeneration (AMD) using a retinal function imager. Sixty eyes with wet AMD were compared to 53 control eyes and the average blood flow...WATCH: Novel imaging technology reveals role of immune cells in early diabetic cataract development
In this video interview, Proffessor Ali Hafezi-Moghadam and Professor Dr. Christoph Rußmann discuss their findings on the role of immune cells in early diabetic cataract development.
Clinical outcomes of AMT in acute ocular chemical injury
This is a retrospective study of patients from two units in Germany and UK between 1998 and 2008. The ocular chemical burns were classified by Roper-Hall and Dua classifications. A total of 72 eyes of 54 patients aged 37.3 years...
Results of STENTube for lacrimal intubation
The STENTube is designed with a varied diameter – a thin central segment with a diameter of 0.86mm and distal tube segments with larger 1.3mm diameter. The thin central segment is exposed at the medial canthus. The distal tubes tamponade...
Surgical complications of ReLEx
Femtosecond laser refractive lenticule extraction (ReLEx) is a novel procedure for treatment of myopia and myopic astigmatism, which eliminates the use of microkeratome and excimer laser. Currently there are two techniques: FLEx – femtosecond lenticule extraction (similar to conventional LASIK)...
ABCA1 mediates lipid efflux in the retina
Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly population. There are two forms of AMD, dry and wet, the latter so named because of the presence of choroidal neovascularisation. Both forms lead to retinal pigment...
VDT use and dry eye disease in children
There has been an increase in the amount of work performed using video display terminals. This study compared school children with and without dry eye disease and evaluated the risk factors of dry eye disease and evaluated the risk factors...
Fluorescein angiography and OCT in myopic CNV
Fluorescein angiography (FA) and spectral-domain optical coherence tomography (OCT) are the most common examinations used in the management of anti-VEGF therapy in choroidal neovascularisation (CNV). In comparison to FA, OCT provides a noninvasive evaluation of the macula. Myopic CNV are...
RPE use similar pathway to regulatory T cells to inhibit immune response
Retinal pigment epithelial (RPE) cells form an important part of the blood-retinal barrier that protects the neuronal cells responsible for sight. RPE cells are involved in innate and adaptive immune responses via expression of surface molecules and release of cytokines....
Neurotrophic keratitis
The authors present an overview of the aetiology, diagnosis, current and future management options of neurotrophic keratitis. This is a degenerative corneal disease that occurs following the compromise of trigeminal innervation, leading to hypoesthesia and / or anaesthesia. The aetiology...
