The potential of small molecule brain-derived neurotrophic factor: mimetics to treat inherited retinal degeneration

Is there a need for small molecule neuroprotectants in inherited retinal degeneration (iRDs)? iRDs are a heterogeneous cluster of diseases which lead to blindness in 1 in every 2–3000 people. A plethora of causative genetic defects were revealed in the last 30 years. Current research focuses on development of pharmacological, biological or mechanical implant treatments. Gene therapy demonstrated success in patients with specific genetic mutations and Luxturna, recently approved by the FDA for RPE65 related disease, entered the market at a cost of $425,000 per eye.
