Purpose: To report four cases of normal-tension glaucoma with disk hemorrhage in one eye and branch retinal vein occlusion in the contralateral eye.
Design: Observational case series.
Methods: Four cases of normal-tension glaucoma with disk hemorrhage in one eye and branch retinal vein occlusion in the contralateral eye were detected within a 1-year period.
Results: Mean patient age was 57 +/- 10 years. Three patients had systemic hypertension, two bilateral normal-tension glaucoma, and all four bilateral peripapillary atrophy. There was no significant difference in intraocular pressure between the disk hemorrhage eyes and the contralateral eyes with branch retinal vein occlusion.
Conclusion: Some normal-tension glaucoma patients with disk hemorrhage may have a pathogenic mechanism in combination with branch retinal vein occlusion.
