Purpose: To report the clinical findings of 7 patients with a vitreous hemorrhage (VH) caused by a ruptured retinal macroaneurysm. Methods: Interventional case series. The medical records of 7 patients with a VH caused by a ruptured macroaneurysm and treated by either medication or vitrectomy were reviewed. The main outcome measures were the visual acuity, appearance of the fundus and optical coherence tomographic findings. Results: Two patients, aged 49 and 58 years, had retinal macroaneurysms at the optic disc. The retinal macroaneurysm in the other 5 eyes (mean age 79.0 years) was not at the optic disc. The VH was completely resolved in all 7 patients. The visual acuity improved in all eyes and remained stable for at least 6 months after the treatments (p = 0.0478). Conclusions: The improvement of the visual acuity in all eyes indicates that the prognosis of eyes with a VH caused by a ruptured retinal macroaneurysm is good.
