Choroidal macrovessel and persistent metamorphopsia after epiretinal membrane surgery.

Area of Science:

• Ophthalmology
• Retinal Imaging
• Vascular Anomalies

Background:

• Epiretinal membrane (ERM) surgery aims to restore visual acuity.
• Persistent metamorphopsia can occur post-ERM surgery, necessitating further investigation.

Observation:

• A 59-year-old male presented with persistent metamorphopsia in the right eye post-ERM surgery.
• Multimodal imaging identified a choroidal macrovessel impacting the foveal structure.

Findings:

• Enhanced depth imaging optical coherence tomography (EDI-OCT) showed deformation of the ellipsoid zone (EZ) and retinal pigment epithelium (RPE) due to the choroidal macrovessel.
• The choroidal macrovessel extended from the fovea to the temporal macula.

Implications:

• This case highlights the potential role of choroidal macrovessels in causing persistent metamorphopsia after ERM surgery.
• Understanding these vascular anomalies is crucial for diagnosing and managing complex retinal conditions.
