Abstract:
Glaucoma is a progressive optic neuropathy, characterised by optic nerve damage, visual field loss, and it may be associated with either elevated or normal intraocular pressure. It may be primary, or it may be secondary to other causes. Treatment is aimed at reducing intraocular pressure as this is the only modifiable risk factor. Treatment involves medicated eye drops which are used on a daily basis, each with their own ocular and systemic side effects. Approximately half of glaucomatous patients are unaware that they are affected by this disease. Family history is a strong risk factor for all types of glaucoma, and because early stages of this irreversible disease go unnoticed, early detection is imperative. It is important that optometrists, being primary healthcare practitioners, are competent at detection and management of glaucoma. This thesis presents a series of case studies that illustrate the many forms of glaucoma and the diagnostic and therapeutic challenges that each presents. Early detection and intervention have become increasingly important. Better access to eye care for New Zealanders means earlier detection, a reduction of the burden on the public health system, and consequently improved wellbeing and health overall.
