How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Healthy lifestyle changes and stress management
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Ophthalmologic evaluation
Comprehensive eye examination including electroretinogram follow-up to monitor the supernormal b-wave finding and assess for any associated retinal dysfunction.
Antioxidant supplementation review
Evaluation of current antioxidant supplementation and dietary intake, as oxidative stress may influence retinal electrophysiology. Supplementation should be medically supervised.
Additional treatment options
Electroretinogram repeat testing
Confirmatory ERG testing to establish whether the supernormal finding is persistent or transient, which helps guide further management decisions.
procedureBlue light protection
Use of blue light filtering lenses and reduced screen time to minimize potential oxidative stress on retinal photoreceptors.
lifestyleLutein and zeaxanthin enrichment
Increased intake of macular pigments through leafy greens and fortified foods to support retinal health and photoreceptor function.
dietaryWhen to seek medical help
