The diurnal curves and tonography result were studied in 367 eyes of 236 patients with ocular hypertension ≥ 20 mmHg. The outflow values of 97 eyes with glaucomatous optic nerve damage (OND) were compared with those of eyes with similar pressure but without optic nerve damage. The coefficients were lower in the former than in the latter group, but the differences were small and deviations great. Tonography performed in addition to the diurnal curve seems to be of very limited value in predicting the risk of glaucomatous damage in an individual eye with ocular hypertension. The outflow coefficient was lower for eyes with the pseudoexfoliation syndrome than for eyes with similar pressure without pseudoexfoliation.
