Referral to a retinal specialist for dilated fundus examination, optical coherence tomography, and detailed functional assessment to identify underlying etiology.
Additional treatment options
Retinal Supportive Nutrition
Supplementation with antioxidants including vitamin A, lutein, zeaxanthin, and omega-3 fatty acids to support retinal cell function and potentially improve timing abnormalities.
dietaryBlue Light Protection and Environmental Modification
Use of blue-light filtering glasses and reduction of screen time exposure to minimize oxidative stress on retinal photoreceptors and support normal ERG timing.
lifestyleAcupuncture for Visual Function Support
Traditional acupuncture targeting eye-related meridians may complement conventional care by improving microcirculation and neural conduction timing.
