Primary angle-closure glaucoma: A review of provocative tests

Abstract

Provocative tests for angle-closure glaucoma are highly desirable but pupil dilatation with tropine drugs and dark-room tests are theoretically unsuitable. At present, careful clinical history-taking and examination are more accurate than provocative tests for deciding in favour of surgery upon second eyes or eyes suspected of having had a previous angle-closure attack. Present provocative tests are too inaccurate, too time-consuming, or too dangerous for symptom-free eyes found to have shallow anterior chambers and narrow angles on routine examinations. Attempts to find better provocative tests should continue.
