Long-term outcomes of deep anterior lamellar versus penetrating keratoplasty for keratoconus

This is a retrospective consecutive and comparative case series of keratoplasties (228 deep anterior lamellar keratoplasties (DALKs) and 274 penetrating keratoplasties (PKs)) in a single centre by one surgeon in France, between 1993 and 2021. Graft survival was 96.7% at...

Moorfields cataract, medical retina and disc assessment

The Cataract/medical retina/ disc assessment short course has been designed to meet the training needs of band 6’s and 7s who wish to develop their knowledge and skills in disease recognition, management and intervention of cataract, medical retina and disc...

Protecting retinal ganglion cells

Glaucoma is considered to be a heterogeneous group of conditions giving retinal ganglion cells (RGC) damage. Lowering intraocular pressure (IOP) reduces the risk of progressive RGC loss in glaucoma. Regeneration of the optic nerve has been shown to restore some...

Management of a giant pigment epithelium detachment with transition from half- to full-dose aflibercept

This case report describes the management of a giant pigment epithelial detachment (PED) in neovascular age-related macular degeneration (nAMD) using half-dose aflibercept. An 80-year-old woman presented with a huge PED (maximum height 1338µm) and multiple risk factors for retinal pigment...

Corneal molecular and cellular biology for refractive surgeon

This is an interesting literature review that looks into the recent advances concerning the corneal molecular and cellular processes that are involved in the wound healing response after excimer laser surface ablation and LASIK surgery. It talks about the complex...

LASEK vs. epi-LASIK for myopia: meta-analysis

Previous studies have produced inconsistent conclusions on the relative benefits between LASEK vs. Epi-LASIK. LASEK uses 20% alcohol to separate an epithelial flap from the Bowman membrane. After ablation, the epithelial flap is repositioned onto the cornea. Epi-LASIK creates the...

Effect of preservative free fluoroquinolones on human corneal epithelial cells in vitro

Fluoroquinolones, including second generation (ofloxacin and ciprofloxacin), third generation (levofloxacin and tosufloxacin) and fourth generation (gatifloxacin and moxifloxacin), are a group of bactericidal agents used to treat multiple ocular infections. The third and fourth generation fluoroquinolones have enhanced Gram-positive activity...

Corneal epithelial thickness values in healthy Turkish children

This study aimed to characterise the normative corneal epithelial thickness profile in healthy Turkish children using anterior segment optical coherence tomography (AS-OCT). This was a retrospective cross-sectional observational study of 86 healthy children aged 7–18 years aged 13.3 ±2.8 years....

The role of inflammation in the pathophysiology of DMO

Diabetic macular oedema (DMO) is a major cause of visual loss in diabetes, with a complex multifactorial pathogenesis. In the UK alone it is estimated that there are nearly 2.5 million diabetic patients aged over 12 years. Approximately 65,000 of...

MicroRNAs in cataract

In an ageing population cataract formation is one of the leading causes of blindness. Cataracts are caused by a failure to clear accumulating aggregated proteins in the lens. MicroRNAs are small non-coding transcripts which bind to specific mRNAs acting at...

Limbal melanocytes and the stem cell niche

The cornea is continually regenerated to maintain clear vision, due to a population of stem cells located in the limbal region between the cornea and the conjunctiva. These limbal stem cells (LESC) reside in crypts in structures called the Pallisades...

Autophagy in lens mitochondria loss

The lens consists of a monolayer of epithelial cells that overlies fibre cells that differentiate from epithelial cells at the equator. While developing, fibre cells need mitochondria to provide energy, as they mature they lose these and other organelles to...
