Knobby eye syndrome

This study used high resolution MRI to demonstrate and evaluate globe shape in axial high myopia and identify and characterise those with prominent equatorial staphylomata that deflect extraocular muscle paths and presumably alter motility patterns in strabismus. The study included...

MicroRNA mediate retinoblastoma signal transduction

MicroRNAs (miR) are small non-coding single-stranded RNA molecules, normally 22 nucleotides long. There is a large family of miR that control protein expression by binding to mRNAs, leading to their degradation. One important role of miR is in tumours where...

Erythropoietin in healing corneal epithelial defects in rabbits

Corneal epithelial defects heal slowly in patients with diabetes, limbal stem cell deficiency and severe chemical burns. Erythropoietin is a glycoprotein hormone that promotes red blood cell proliferation and inhibits apoptosis of erythroid progenitors as well as nonhematopoietic cells. In...

PD-1 and retinal ganglion cell death

Death of retinal ganglion cells (RGC) in conditions like glaucoma leads to permanent visual loss. RGC death can be due to the initial stress such as raised intraocular pressure or secondary to mechanism such as oxidative stress. Programmed cell death-1...

AOP launches research into key reforms proposed for primary eye care services in Wales

The Welsh Government put forward proposals for major reforms of primary eye care services

Don’t ignore the black lesion! It might be mucormycosis

Keeping mucormycosis infection in the foreground of your differential diagnosis, especially in those more vulnerable patients, will help save their lives if recognised and managed appropriately. Mucormycosis is a fulminant infection caused by the fungi of the family Mucoraceae. It...

The challenge of chorioretinal folds in virtual eye clinics

Chorioretinal or choroidal folds are parallel striations involving the retina, retinal pigment epithelium (RPE), Bruch’s membrane, and inner choroid [1]. They can arise from compressive stress on these layers, and their presence often serves as a diagnostic marker for underlying...

Periocular sweat gland carcinomas

This is an interesting review of a rare group of tumours which together comprise the adnexal sweat gland carcinomas. Although there are only 22 patients, this is the largest cohort ever published. The authors summarise the clinical presentation, stage, management...

Non-arteritic anterior ischaemic optic neuropathy in the Asian population

This article provides an evaluation of changes in visual function associated with non-arteritic anterior ischaemic optic neuropathy (NAION) among Korean patients. Visual changes were identified as a reduction in visual acuity by three Snellen lines or a deterioration of visual...

Risks factors for graft preparation failure in DMEK

Diabetes mellitus (DM) makes it more difficult to prepare descemet membrane epithelial keratoplasty (DMEK) grafts due to the ‘stickiness’ of Descemet’s membrane. This retrospective study examined a classification system, where donors were scored points according to their DM related risk...

Tear film thickness after treatment with artificial tears in patients with moderate dry eye disease

In recent years artificial tear drops addressing tear film osmolarity have come onto the market. Increased tear evaporation and reduced tear volume results in tear hyperosmolarity. This triggers an inflammatory process leading to apoptosis of goblet and epithelial cells. Trehalose,...

Ovarian hormones drive onset of Sjogren’s disease in mice

Sjogren’s syndrome (SS) is a debilitating, sight-threatening, systemic autoimmune disease with no effective treatment available. SS is characterised by lacrimal gland lymphocytic infiltration and epithelial cell death, as well as by the presence of serum autoantibodies. Patients have severe dry...
