Retinal detachment and subsequent degeneration of the retina can lead to progressive visual decline due to death of photoreceptor cells, the major light-sensing cells within the eye. Early inflammatory mediators, including components of the alternative complement pathway, are increased in the eye of patients with retinal detachment. Using a mouse model of retinal detachment, Sweigard et al. found that blocking the alternative complement pathway through either genetic or pharmacological means protected photoreceptors from cell death.
