Glaucoma: the value of a diurnal curve and Goldmann visual field

A 35-year-old man was treated with maximum medical therapy for open-angle glaucoma. A diurnal curve revealed that the pressure was not controlled as might have been thought by a single reading. Reference is also made to the value of Goldmann visual field testing, since in this patient visual field defects were discovered with normal, healthy-appearing optic discs. A careful regimen including precise visual field testing and the plotting of the diurnal curve is most important in evaluating ocular hypertension and glaucoma.
