title: Long-term observations after trephination with scleral flap in glaucoma with threatened point of fixation.
abstract: Follow-up examinations 2 months to 9 years after a filtering operation with scleral flap with successful pressure regulation could be carried out in 26 patients with 29 eyes in which a threat to the point of fixation due to glaucoma was present. In the majority of the cases, it was possible to stabilize visual acuity and visual field by the operation. In the remaining cases, there was a slow melting away of the residual visual field without correlation with lens or macular changes or underlying internal conditions.
