A Non-Surgical Approach to Acute Corneal Hydrops in Optometric Practice
If you can quickly resolve oedema in acute hydrops cases, you'll reduce the need for a transplant Topical hyperosmotic: Can reduce corneal oedema (albeit slowly), and improve acuity Topical steroids:…
Glaucoma: The Patient’s Perspective and New Treatment Strategies
RNFL thickness, SAP mean deviation, and age were significantly predictive of reaction times, with worse reaction times observed with low-contrast targets. This information suggests that structural measures, including RNFL...

Case Report: A Mini-Scleral Lens for Visual Rehabilitation of Corneal Leukoma Adherens
Corneal injury either by trauma, surgery or infection often results in severe scarring and generalised or localised leukoma or white vascularized corneal opacities involving the cornea. The affected eye often…
Case Report: Managing Pellucid Marginal Degeneration and Keratoconus with Corneal and Mini-Scleral Lenses
Keratoconus is a bilateral asymmetric non-inflammatory corneal degeneration characterised by localised corneal thinning which leads to ectasia or protrusion of the thinned cornea causing high myopia and irregular astigmatism that...
Case Report: Managing Keratoconus and a Corneal Graft with Semi-Scleral Contact Lenses
Keratoconus is a bilateral asymmetric non-inflammatory corneal degeneration characterised by localised corneal thinning which leads to ectasia or protrusion of the thinned cornea. The corneal thinning and protrusion can occur...
