Long-term handling of open-angle glaucoma: tonography and other prognostic aids

Data from 132 primary open-angle glaucoma cases and from 6 combined open and closed-angle cases, taken from a group of 254 cases with extensively documented material from 10 year or longer follow-up, are used to show that tonographic data are more helpful than other criteria in predicting which cases can be expected to show deterioration, although careful visual field testing and optic disc evaluation remain the ultimate guides.
