Ocular Pressure

In chronic simple (open-angle) glaucoma loss of visual field may be prevented by improving the outflow of aqueous humour from the eye and thus lowering the raised intra-ocular pressure. This is achieved mainly by miotic drugs which constrict the pupil and make the ciliary muscle contract. These either mimic acetylcholine, acting directly on the ciliary muscle, or inhibit cholinesterase and so allow acetylcholine to accumulate.

Aqueous Outflow

The medical control of chronic simple (open-angle) glaucoma is becoming more popular, and newer and more potent drugs have been produced to reduce the intra-ocular pressure. The anticholinesterases are one such group of drugs; they potentiate acetylcholine and increase aqueous outflow from the eye, perhaps by stimulating the ciliary muscle which pulls on the scleral spur, or by direct action on parasympathetic end-organs in the trabecular meshwork. The effect lasts many hours or even several days, thus achieving the uninterrupted control of intra-ocular pressure essential to prevent further loss of visual field.

Ocular Pressure

Normal tension glaucoma is the most common type of glaucoma among people of east Asian countries. While a significant minority of cases of normal tension glaucoma respond to drugs or surgical procedures that lower intra-ocular pressure, most cases continue to progress, resulting in a continuing loss of visual field and blindness. We here review the current state of knowledge of this debilitating disease, and evaluate a promising pilot study showing a potential route to evaluate normal tension glaucoma and to effectively treat it with a vitamin and mineral supplement.

Glaucoma is a complex condition of the eye and the second leading cause of blindness around the globe. It is an ophthalmic neurodegenerative condition and is characterised by a raised intra-ocular pressure (IOP). The latter also constitutes the only modifiable risk factor in glaucoma management. When left untreated patients may gradually experience a visual field loss, and even lose their sight completely. This article provides a brief overview of this condition, the pharmacological treatment options that are available in South Africa, as well as the rational use thereof.
