Retinal detachment is a separation of the neurosensory retina from the retinal pigment epithelium. Most retinal detachments are rhegmatogenous, and identification of risk factors and predisposing lesions are important aspects of patient management. Retinal detachment is relatively rare, but can pose a significant threat to vision if there is macular involvement. Prompt diagnosis combined with patient education and appropriate intervention often can avert irrevocable visual impairment. This paper presents an overview of the categories of retinal detachment, discusses the pathogenesis of the various types of detachment, and provides recommendations for primary care of patients with predisposing factors and high-risk characteristics.
