DALK as an early therapeutic option for Acanthamoeba keratitis
Eleven patients with Acanthamoeba keratitis (AK) were treated by early therapeutic deep anterior lamellar keratoplasty (DALK). All surgeries were performed in patients who had no response to standard medical therapy of chlorhexidine gluconate, propamidine isethionate and neomycin sulphate, within 10-15...

Occult, differentiating, neuroretinitis, non-arteritic anterior ischaemic optic neuropathy, optical coherence tomography
This study evaluates differences between neuroretinitis and non-arteritic anterior ischaemic optic neuropathy (NAAION) in terms of patient demographics, clinical presentation, and optical coherence tomography (OCT) findings. Medical records of patients with a final diagnosis of occult neuroretinitis or NAAION were...

EYE - Vitreo-Retinal
Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...
Principles of contact lens fitting in keratoconus
Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...

EYE - Vitreo-Retinal
The authors looked at macular lesions in eyes with newly diagnosed exudative age-related macular degeneration. The eyes of 23 patients were included and tested for visual acuity, contrast sensitivity, microperimetry, optical coherence tomography (OCT) and fluorescein and indocyanine green angiography....
What’s next in retinal imaging? Faster, deeper and full-on
Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...

EYE - Vitreo-Retinal
Bariatric surgery induces an instant normalisation of blood glucose in as many as 80% of patients with type 2 diabetes. It has been previously reported that diabetic retinopathy (DR) is stable within one year after bariatric surgery. In this study,...

EYE - Vitreo-Retinal
In this retrospective, observational case series, the authors set out to evaluate the morphology of the superficial and deep capillary plexa of eyes that suffered a retinal vein occlusion (RVO) on OCT angiography (OCTA) and compare the findings with fluorescein...
Can OCT predict Alzheimer’s disease?
Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: Can OCT predict Alzheimer’s disease? In 1986 Hinton et al. demonstrated evidence of optic nerve degeneration...Glaucoma UK’s World Glaucoma Week campaign to increase awareness of glaucoma risk factors

World Glaucoma Week is an annual initiative which brings health organisation and charities from around the world together to amplify health messages relating to glaucoma and raise awareness of the disease.
Handheld OCT in children with Down’s syndrome
This article investigated the use of handheld optical coherence tomography (OCT) in children with Down’s syndrome. Fourteen children were recruited to the study with a mean age of 6 years and 10 months with 57% male. All patients were dilated....

EYE - Vitreo-Retinal
Blue light causes photo-oxidative retinal injury and macular pigment (MP), with lutein, zeaxanthin and mesozeaxanthin as the main components, as a filter that protects the macula from this damage. Previous studies indicated that low levels of macular pigment optical density...
