Abstract Twenty-six eyes of twenty patients with established low tension glaucoma, who had either a ‘double flap’ Scheie filtering operation or a trabeculectomy, were followed over a period ranging from one to ten years, with a median of three years. These 26 eyes include two second eyes that served as a contralateral control eye until the visual field deteriorated. All 26 eyes showed progression of visual field defects preoperatively, while postoperatively only 2 eyes showed further progression. Of the 16 nonoperated contralateral eyes, 7 showed progression of visual field defects over the same follow-up period. Two of these 7 eyes had to be operated during the study-period. The difference in progression between the operated and the non-operated eyes was significant (P〈0.01). The diltering procedure provided a reduction in IOP of 20% or more in 21 of 26 eyes. There was a significant difference in the mean intraocular pressure (IOP) between the operated and the non-operated contralateral eye of 6.8 mmHg (37%) at one year postoperatively. The diurnal variation decreased highly significantly from 4.3 to 2.1 mmHg (P〈0.001). It is concluded that filtering surgery in low tension glaucoma may result not only in a significant lowering of IOP, but is also effective in slowing further deterioration of the visual fields.
