Summary
Retinal macroaneurysms causing hemorrhages can improve vision after bleeding absorption. However, the risk of recurrent vitreous hemorrhage indicates a need for considering aneurysm treatment.
Area of Science:
- Ophthalmology
- Vascular Medicine
Background:
- Spontaneous retinal and vitreous hemorrhages can be associated with underlying vascular abnormalities.
- Retinal macroaneurysms are dilations of retinal arteries that may lead to bleeding.
Purpose of the Study:
- To evaluate the clinical presentation and outcomes of patients with retinal macroaneurysms presenting with spontaneous hemorrhages.
- To investigate the changes in macroaneurysms and visual function following hemorrhagic events.
Main Methods:
- Retrospective case series of six patients with spontaneous retinal and/or vitreous hemorrhages.
- Fluorescein angiography was used to diagnose retinal macroaneurysms.
- Clinical follow-up assessed visual acuity and fundus changes.
Main Results:
- All six patients had macroaneurysms of major retinal arteries and evidence of other vascular disease.
- Five patients showed significant visual improvement as hemorrhages absorbed.
- Macroaneurysms appeared to decrease in size due to arterial wall fibrosis.
- One patient experienced a recurrent vitreous hemorrhage months later.
Conclusions:
- Retinal macroaneurysms are a potential cause of spontaneous vitreous and retinal hemorrhages.
- While vision may improve with hemorrhage absorption, the risk of recurrence necessitates consideration of treatment options for these aneurysms.
