Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Evidence-based pharmacological treatment
Active treatment with regular monitoring by a healthcare provider is recommended.
Regular ophthalmologic monitoring
Progressive monitoring of visual acuity, visual fields, and retinal function to track disease progression and guide interventions.
UV and bright light protection
Use of UV-blocking sunglasses and protective lenses to reduce light sensitivity and potentially slow photoreceptor damage.
Additional treatment options
Low vision rehabilitation
Training in use of magnifying devices, adaptive technologies, and orientation techniques to maximize remaining vision.
lifestylePsychological support and counseling
Counseling services to address vision loss-related anxiety, depression, and adjustment to progressive visual impairment.
psychologicalVitamin A supplementation
Controlled vitamin A supplementation under ophthalmologic supervision, as deficiency may accelerate cone-rod dystrophy.
