Long-Term Follow-Up Study of Autosomal Dominant Optic Atrophy in an Australian Population.

Purpose: This study aimed to describe the phenotype of Australian patients with a clinical diagnosis of dominant optic atrophy (DOA) and provide long-term follow-up data on its natural history.

Design: Retrospective analysis.

Methods: All patients with the clinical diagnosis of DOA observed during a 30-year period at a single tertiary referral center (Save Sight Institute, Sydney Eye Hospital, Sydney, Australia) with at least 12 months of follow-up were included in the study.

Trypan blue to assess Baerveldt tube patency after repair of its obstruction.

Tubal obstruction is a recognized complication of glaucoma drainage implants. In correcting a blocked tube, the surgeon may be uncertain about shunt competence even after removing the suspected cause of obstruction. We report the use of trypan blue dye to show tubal patency directly after the repair of a blocked Baerveldt tube.
