“…This study confirms the results of others (Werner et al 1977;Kidd et al 1985) that there are a number of patients who continue to lose visual field after glaucoma surgery despite the lowering of the IOP to a statistically normal level. More than 1/4 of the patients in the present study showed progression of the visual field defects at the 5-year visit.…”

The long-term changes of the visual field defects of 54 glaucoma patients operated on with trabeculectomy were reviewed. Five years after operation 28% of the patients had suffered from further loss of visual field despite lowering of the intraocular pressure (IOP). All but three of these patients had their postoperative IOP regulated within statistically normal levels (11-21 mmHg). All patients with continued loss of postoperative field were generated from groups of patients with milder to moderate preoperative field defects (stages 0-III classification of Aulhorn, 1979). No patients suffered from sudden field loss after surgery. The mean of the preoperative IOP and the mean of the percent IOP reduction postoperatively were not significantly different in patients with or without continued postoperative visual field loss. This indicates that other factors than normalization of intraocular pressure play an important role in the group of patients with progression of visual field defects following surgery.

“…However, it has been reported that a significant group of patients still experience progression of glaucoma despite IOP measurements in the ophthalmologist's office within normal limits. [1][2][3][4] However, it has been suggested that this finding may be explained by the occurrence of pressure peaks not detected by single measurements in the clinic. Drance 5 demonstrated that almost one third of patients with single IOP measurements during office hours may present pressure peaks only detected during a 24-hour pressure curve.…”

“…Despite apparent satisfactory pressure control, visual function declines progressively in a proportion of patients. [1][2][3] Changes in body position have been shown to affect IOP. [4][5][6][7][8][9] It is generally believed that the postural effect of the IOP in glaucomatous eyes is greater than that in normal eyes.…”
