The subtitle of the recent study by Kass et al1 is too sensational for the modest results. Even if an ophthalmologist treated all patients with the pressure elevations they describe, he or she could prevent only 1 case of glaucoma per 100 patients treated each year (9.5% in observation eyes − 4.4% in treated eyes over 5 years). This preventable case of glaucoma would have early disc changes and no field loss or early field loss and would, in all probability, be responsive to ocular hypotensive medication.
