Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Regular Ophthalmologic Examinations
Comprehensive eye exams monitor disease progression, assess visual acuity, and evaluate color vision and central visual field. Regular imaging helps track any retinal changes.
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
Corrective Lens Prescription
Prescription eyeglasses or contact lenses address myopia and may help optimize remaining visual function. Regular updates to prescriptions ensure optimal visual correction as the condition is monitored.
Additional treatment options
Low Vision Rehabilitation
Low vision specialists provide training in using remaining vision efficiently through magnification devices, specialized lighting, and adaptive techniques for daily activities.
complementaryRefractive Surgery Consultation
Laser refractive surgery may be considered in select cases to reduce myopia, though vision may continue to change over time. Thorough evaluation determines candidacy.
surgicalEnvironmental Adaptations
Optimizing home and work environments with appropriate lighting, contrast enhancement, and glare reduction improves functional vision. Digital accessibility features can support daily tasks.
