Both the American Academy of Ophthalmology (AAO) and the European Glaucoma Society (EGS) have updated their preferred practice regimens to recognize or recommend SLT as an initial intervention for glaucoma and the NICE UK are now guiding doctors to use SLT before drops.

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...

Retinoblastoma chemotherapeutic drugs and their toxic effects on RPE cells

There is reported clinical evidence of retinal pigment epithelium (RPE) alterations after intra-arterial (IAC) and intravitreal chemotherapy (IViC) of retinoblastoma. The purpose of this study was to investigate the cellular toxic effects of melphalan, topotecan and carboplatin on the RPE...

Penetrating keratoplasties in infants

This retrospective review looked at endothelial cell counts (ECC) following penetrating keratoplasties (PKP) performed in infants within the first year of their life. One hundred eyes of 71 patients had their first PKP during the study period (1998-2013). In 30%...

Transfected RPE cells inhibit AMD in rats

Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly. Wet AMD is characterised by choroidal neovascularisation, new vessels into the retina, leading to leakage and tissue damage. Many proangiogenic factors particularly vascular endothelial growth factor (VEGF)...

Long-term effect of YAG LPI on corneal endothelium in PACS

This is a single-centre randomised controlled trial of 875 patients with bilateral primary angle closure suspect (PACS) who received YAG laser iridotomy (LPI) prophylactic treatment in one eye randomly and the fellow eye served as control over 72 months. Central...

Medial rectus anatomy in exotropia

This study investigates the differences between extraocular muscles in patients with intermittent exotropia and normal controls regarding muscle fibre arrangement and diameter, and distribution and activation of satellite cells. Fifteen patients were recruited having medial rectus resection surgery. Resection sections...

Does lower eyelid entropion repair alter corneal topography?

The authors aimed to analyse the corneal morphology before and after advancement of posterior lower eyelid retractors (LERs) alone or in combination with a lateral tarsal strip (LTS) for lower eyelid involutional entropion. Retrospective analysis of 24 consecutive elderly patients...

Changes in corneal endothelial layer after strabismus surgery

The purpose of this study was to investigate the changes in the corneal endothelial layer by specular microscopy after surgery in patients with horizontal and oblique strabismus. Eighty-three eyes of 56 patients were evaluated prospectively. There were three subgroups: one...

Upper eyelid ulceration as a presenting sign of frontal sinus mucocele

Introduction A sinus mucocele is an epithelium-lined sac filled with mucus and desquamated epithelium. It forms secondary to inflammatory processes that occur in a sinus with an obstructed ostium. Predisposing conditions include previous trauma, surgery, tumours, anatomical abnormalities, and chronic...

The management of possibly progressive pterygium

A 43-year-old Sudanese male patient is referred by his GP with a fleshy lesion encroaching the nasal cornea for the last six months. History Make note of: risk factors, i.e. UV exposure and ocular irritation - history of living in...
