Retinal artery macroaneurysm complicated with subhyaloid hemorrhage: two case reports

Area of Science:

• Ophthalmology
• Vascular Medicine

Background:

• Retinal artery macroaneurysm (RAM) is an uncommon vascular condition, typically affecting elderly women with systemic vascular diseases.
• Most RAM cases are asymptomatic and resolve spontaneously without intervention.

Observation:

• Two cases of RAM complicated by subhyaloid hemorrhage are presented.
• One patient with hypertension experienced decreased visual acuity; laser hyaloidotomy improved vision.
• Another patient with rheumatoid arthritis received anti-VEGF injections for RAM complications, resulting in poor visual outcomes.

Findings:

• Vision loss in RAM complications often stems from hemorrhages and macular exudations.
• Treatment outcomes for RAM complications vary significantly, with no universally established optimal therapy.
• Laser hyaloidotomy showed promise in one case for relieving hemorrhage and improving vision.

Implications:

• This review highlights the diverse treatment approaches for RAM complications, emphasizing the need for further research into optimal therapeutic strategies.
• Understanding the benefits and limitations of different treatments is crucial for managing RAM and its associated vision loss.
• The study underscores the variability in visual recovery following interventions for RAM-related complications.
