The results of the last survey Aug24

In the first case we were faced with a 55-year-old patient with narrow, potentially occludable drainage angles, no significant cataract, and persistently raised intraocular pressures (IOPs) of 28mmHg with early disc compromise, and normal vision in each eye. It is...

Traumatic ‘toy’ gun injury leading to permanent vision loss

Pseudoxanthoma elasticum (PXE) is a progressive, inherited disorder of connective tissue that affects the skin, cardiovascular system and retina. Ocular manifestations of the disease are related to Bruch’s membrane, a thin elastic tissue layer located between the retinal pigment epithelium...

Improved efficacy expected with second-generation microinvasive glaucoma surgery (MIGS) devices

Microinvasive surgical approaches to primary open-angle glaucoma (POAG) offer minimally traumatic options for effective intraocular pressure (IOP) reduction in appropriately selected glaucoma patients. Increases in laser trabeculoplasty rates and wider adoption of glaucoma drainage device filtration procedures, together with the...

A look into the IOL space

Advances in the design and performance of intraocular lenses (IOLs) continue to be driven by demand for better outcomes, presbyopia correction and spectacle independence, alongside a better understanding of the dynamics of the crystalline lens, newer theories of accommodation and...

Randomisation, confounding & observational methods in ophthalmic epidemiology

Randomisation and confounding Understanding the relationship between an exposure and an outcome of interest is the central challenge in ophthalmic epidemiology. The exposure may be aetiological, taking the form of a putative risk biological factor, or therapeutic, in the form...
