Frequency of Vitreous Hemorrhage Caused by Retinal Macroaneurysm
- The frequency of vitreous hemorrhage caused by a retinal macroaneurysm is not explicitly stated in the provided studies as a specific percentage or incidence rate.
- However, according to 1, retinal macroaneurysm was found to be the cause of hemorrhage in 7 out of 95 eyes with dense spontaneous vitreous hemorrhage, suggesting that it is a relatively rare cause.
- In another study 2, four patients with vitreous hemorrhage of unknown origin were found to have retinal macroaneurysms, highlighting the potential for this condition to be misdiagnosed.
- A case report 3 describes a novel case of vitreous hemorrhage associated with suspected rupture of a large retinal arterial macroaneurysm on the optic disc, further illustrating the potential for retinal macroaneurysms to cause vitreous hemorrhage.
- Other studies 4, 5 mention retinal macroaneurysm as a possible cause of vitreous hemorrhage, but do not provide specific frequency or incidence data.
