AIM: To investigate the disease progression and final visual outcome of glaucoma patients with poor life expectancy, compared to matched patients with a longer life expectancy. METHOD: Visual fields at diagnosis and at the last ophthalmic appointment before death were analysed for glaucoma patients referred between 1991 and 1995, and deceased before the end of 2001. These patients were matched to the patients living beyond 2001. Functional vision was also assessed, and classified as better than the NHS partial sighted criteria. RESULTS: A total of 61 deceased patients were identified, resulting in 40 matched pairs. In all, 6.5% of the patients with poor life expectancy progressed from functional vision to beyond partial sighted criteria, and none of the matched patients progressed to this extent. At final assessment an association between poor life expectancy and progression beyond functional vision was found existing (P = 0.02), with a lesser association at diagnosis (P = 0.06). Visual field scores of the matched pairs who had test results available for both initial and final assessment (n = 23 pairs) showed no statistically significant difference between the two groups at diagnosis (P = 0.52); However, a significant difference at final the assessment did exist (P = 0.042). No difference between the initial (off medication) intraocular pressures (IOPs) was found (P = 0.82). At the final assessment a significant difference existed (P = 0.025), with the surviving group having a higher final mean pressure (15.9 mmHg, SD 2.8, vs 18.3 mmHg, SD 4.9). CONCLUSION: Patients with poor life expectancy progressed more than the matched surviving patients, when measured from an initially similar position, despite better IOP control.
