Serous macular detachment associated with retinal arterial macroaneurysm

Area of Science:

• Ophthalmology
• Medical Imaging
• Retinal Diseases

Background:

• Retinal arterial macroaneurysms are vascular abnormalities that can lead to vision-threatening complications.
• Macular edema, characterized by fluid accumulation in the macula, is a common consequence.

Purpose of the Study:

• To describe the optical coherence tomography (OCT) findings in eyes with macular edema secondary to retinal arterial macroaneurysms.
• To evaluate the efficacy of treatment for this condition.

Main Methods:

• Retrospective examination of six eyes using OCT.
• Fluorescein and indocyanine green angiography were performed.
• Direct laser photocoagulation was applied to the macroaneurysms in five eyes.
• Foveal thickness, serous macular detachment height, and visual acuity (VA) were monitored.

Main Results:

• All six eyes presented with serous macular detachment and retinal swelling, without cystoid macular edema.
• OCT confirmed leakage solely from the macroaneurysms.
• Complete resolution of macular edema occurred within 1 to 4 months post-treatment.
• Visual acuity improved by more than two lines in all eyes.

Conclusions:

• Retinal arterial macroaneurysms can cause serous macular detachment due to fluid leakage.
• OCT is valuable for diagnosing and monitoring this condition.
• Laser photocoagulation appears effective in resolving macular edema and improving VA.
