‘Typically benign’ retinal venous malformations need neuroimaging

PHOENIX — Patients diagnosed with retinal venous malformations should always undergo additional imaging to rule out microvascular or cerebral changes, according to a poster here.“Retinal venous malformations are an abnormal vessel, typically a vein, which crosses the horizontal raphe and passes through the macula,” Brittney Brady, OD, FAAO, associate professor at Illinois College of Optometry, told Healio. “While considered benign and likely underreported, vision loss secondary to retinal venous malformations may occur. ...

AI Summary

Quick Take

Patients diagnosed with retinal venous malformations (RVMs) should undergo neuroimaging to rule out associated microvascular or cerebral changes. While these abnormal vessels crossing the horizontal raphe are often dismissed as benign, they can lead to vision loss and may indicate underlying neurological risks.

Why It Matters

This recommendation challenges the traditional view of retinal venous malformations as incidental, harmless findings. By linking these specific ocular vessels to potential cerebral changes, the guidance elevates the optometrist's role in systemic health screening. Identifying these malformations is no longer just about monitoring for local vision loss, but about acting as a gateway to neurological evaluation for potentially serious vascular issues.

Key Findings

Retinal venous malformations are characterized by abnormal vessels, typically veins, that cross the horizontal raphe and pass through the macula.
Although traditionally considered benign and likely underreported, these malformations can cause secondary vision loss.
The presence of an RVM is a clinical indicator that necessitates additional imaging to screen for cerebral or microvascular involvement.
Clinical experts suggest that the 'benign' label may be misleading given the potential for systemic vascular associations.

Practice Implications

Clinicians should perform a thorough retinal evaluation to identify vessels crossing the horizontal raphe, particularly those involving the macula. Once an RVM is identified, the standard of care should shift from simple observation to a referral for neuroimaging to ensure there are no concurrent intracranial vascular anomalies.
