C-13472 O/SP/AS Medical management of glaucoma
11/03/10
Although glaucoma is largely managed by ophthalmologists in a hospital setting, there are many optometrists who are intending, or already are, practising glaucoma management in a shared care setting, either in their own practice, in a hospital or at a polyclinic. This article is aimed to provide an overview of management of glaucoma by optometrists, to equip them with the necessary skills to perform this service. Before discussing the actual medical management options, it has to be emphasised that correct diagnosis based on the patients history and examination is an essential precursor to correct treatment.

C-13056 The interaction between contact lenses and the tear film
26/02/10

This interaction between contact lenses and the tear film is a complex and a dynamic one which influences several aspects of ocular physiology as well as patient safety, vision comfort. Appreciating the potential influence of this interaction is important in the recognition of adverse signs and consequently, in the management of contact lens patients
