Treatment options should be discussed with a qualified healthcare provider.
Flicker ERG Serial Monitoring
Regular flicker electroretinogram testing to assess cone system function and temporal resolution, tracking disease progression or treatment response.
Cone System Function Optimization
Pharmacologic intervention targeting identified cone pathway dysfunction including treatments for autoimmune retinopathy or nutritional deficiencies affecting cone response.
Additional treatment options
Diagnostic Electrophysiology Workup
Comprehensive electrophysiologic testing including full-field ERG, pattern ERG, and EOG to fully characterize retinal dysfunction and guide management.
procedureLight Adaptation Management
Environmental modifications including appropriate lighting conditions and glare reduction strategies to optimize visual function given abnormal flicker responses.
lifestyleMacular Pigment Enhancement
Dietary supplementation with lutein, zeaxanthin, and meso-zeaxanthin to enhance macular function and support cone-mediated flicker responses.
