Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Complete vision loss
Total loss of vision in one or both eyes, representing advanced disease progression.
Sudden vision loss is a medical emergency. Seek immediate emergency care or call emergency services.
Night blindness
(ophthalmologic)Difficulty seeing in low light or darkness, often noticed first in dimly lit environments.
Frequency: 80-90% of patients
Reduced peripheral vision
(ophthalmologic)Gradual loss of side vision, making it difficult to see objects to the side without turning the head.
Frequency: 70-80% of patients
Decreased visual acuity
(ophthalmologic)Blurred or hazy vision that cannot be fully corrected with glasses or contact lenses.
Frequency: 60-70% of patients
Photophobia
(ophthalmologic)Increased sensitivity to light that causes discomfort or pain in bright environments.
Frequency: 50-60% of patients
Color vision abnormalities
(ophthalmologic)Difficulty distinguishing certain colors, particularly blue and yellow tones.
Frequency: 40-50% of patients
Headaches with visual effort
(neurologic)Frequent headaches that occur during or after activities requiring visual focus.
Frequency: 35-45% of patients
Central vision loss
(ophthalmologic)Progressive loss of the central visual field, affecting the ability to read or recognize faces.
Frequency: 15-25% of patients
Photopsia
(ophthalmologic)Seeing flashes of light or floating spots in the visual field.
Frequency: 2-5% of patients
Diagnosis and tests
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.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Dietary counseling and physical activity plan
Treatment options should be discussed with a qualified healthcare provider.
Vitamin A supplementation
High-dose vitamin A therapy to support retinal photoreceptor function in conditions affecting the electroretinogram. Essential for rhodopsin synthesis and retinal pigment epithelium maintenance.
Regular electroretinography and visual field testing
Scheduled diagnostic testing to track disease progression and evaluate treatment response. Essential for adjusting management strategies and predicting functional outcomes.
Additional treatment options
Omega-3 fatty acid supplementation
Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) supplementation to support retinal cell membrane integrity and function. May help preserve photoreceptor health.
dietaryUV-protective eyewear
Daily use of high-quality sunglasses and blue-light filtering lenses to reduce oxidative damage to retinal photoreceptors and slow disease progression.
lifestyleVision rehabilitation and counseling
Comprehensive support including low vision aids training, orientation and mobility training, and psychological support to help patients adapt to visual changes associated with electroretinogram abnormalities.
psychologicalWhen to seek medical help
