Silver Book Fact

Treatment of patients with advanced dry age-related macular degeneration (AMD) with ciliary neurotrophic factor (CNTF) implants resulted in stabilization of visual acuity.  A sub-group analysis found that 100% of patients receiving a high-dose lost <15 letters of acuity–compared with 55.6% in the combined low-dose/sham group.  The high-dose group had a 0.6 mean letter gain while the low-dose/sham group had a mean 9.7 letter loss.
