Objective:

To quantify the absolute and relative risks of retinal detachment in primary care settings, particularly focusing on patients presenting with floaters, flashes, or both.

Approach:

Key Findings:

Retinal detachment occurred in 6% of episodes involving floaters alone, 5% for flashes alone, and 8% for both symptoms, with adjustments for age and sex showing no statistically significant differences.
Patients with many floaters (10 or more) had over fourfold increased risk compared to those with flashes alone, particularly when symptoms were acute (14 days or less).
Acute symptoms significantly increased the risk of retinal detachment.

Interpretation:

Floaters, especially when numerous or acute, may indicate a higher risk of retinal detachment than previously emphasized, suggesting a need for urgent referral to ophthalmology for patients presenting with these symptoms.

Limitations:

Not all retinal detachment cases presented with floaters or flashes, indicating the need for comprehensive assessment.
Common alternative diagnoses were identified, including posterior vitreous detachment and migraine, which may complicate clinical decision-making.

Conclusion:

The study advocates for a more evidence-based approach in primary care, emphasizing the importance of floaters in risk assessment for retinal detachment and recommending urgent referral for patients with recent-onset or multiple floaters.
