PURPOSE: To investigate if patients with exfoliation glaucoma (XFG) with cardiovascular disease (CVD) require different target intraocular pressure (IOP) compared to patients with XFG with no CVD for long-term stability. METHODS: A retrospective, multicenter, observational cohort analysis included consecutive patients with XFG from 9 European academic centers, with a minimum of 5 years follow-up. RESULTS: In 201 patients, there was a statistical difference between progressed and non-progressed patients in mean (p=0.0049) and peak (p=0.015) IOP, variance of IOP (p=0.028), and number of medicine changes/year (p=0.0037). At a mean IOP ?22 mmHg, patients progressed in 84% (32/38), between 14 and 21 mmHg in 54% (81/151), and at ?13 mmHg in 33% (4/12). There was no difference in the rate of progression between groups based on CVD history (p=0.65). However, IOP that allowed ?50% progression rate for patients with mild or no CVD was ?20-21 mmHg and ?18 mmHg for patients with severe disease. Further, at IOP ?20 mmHg, 8% (1/12) of patients with severe CVD remained stable in contrast to 38% (16/42) of patients with mild and 21% (4/19) with no CVD history (p=0.0093). By multivariant regression analysis of the IOP and CVD measures, mean IOP was a risk factor for progression (p=0.0097). CONCLUSIONS: Although IOP is the main determinant of progression in XFG under treatment, history of severe CVD should be further investigated as potential risk factor for glaucomatous progression.
