Contradicting results concerning intraocular pressure (IOP) control and visual field deterioration are presented. Some of these inconsistencies may be due to the statistical method of analysis. Sixty primary open-angle glaucoma (POAG) patients with a perimetric follow-up of over three years were selected. Mean and maximum IOP was considered during the same period. The patients were divided into two groups according to IOP control (well-controlled or poorly-controlled). Visual field progression was defined as a reduction in sensitivity over the fifth percentile at more than four points. Mean IOPs were not significantly different in the group of patients with a visual field deterioration compared to the stable ones, but the percentage of patients with a visual field deterioration was significantly higher in patients with higher IOP. This holds especially true if IOP below 16 mmHg (G) is considered to be the 'target pressure'. IOP reduction seems to play an essential role in visual field progression. In glaucomatous patients, a strict (< 16 mmHg (G)) might be necessary.
