Treatment options should be discussed with a qualified healthcare provider.

lifestyle
2

Serial electroretinogram testing

Regular dim flash ERG monitoring to assess scotopic retinal function and detect progression of rod-system abnormalities. Consistent testing provides objective measures of treatment response.

monitoring
3

Low light environment optimization

Avoiding bright light exposure and using low-intensity lighting at home can reduce photoreceptor stress. This behavioral modification helps manage symptoms associated with dim flash ERG abnormalities.

lifestyle

Additional treatment options

Vitamin A and omega-3 supplementation

Targeted nutritional support with vitamin A and essential fatty acids supports rod photoreceptor function. These nutrients are essential components of the visual pigment cycle and cell membrane structure.

dietary

Dark adaptation testing and training

Specialized testing to evaluate dark adaptation kinetics combined with visual training exercises. This helps identify specific deficiencies and may improve functional vision in dim conditions.

procedure

Low vision rehabilitation services

Specialized services providing adaptive techniques and devices for patients with diminished night vision. Training in use of assistive devices improves functional independence in low-light situations.
