Autologous serum eye drops provide lubrication and promote epithelial healing. They have been successfully used in the management of ocular surface disorders such as dry eye disease, persistent epithelial defects and neurotrophic keratopathy for many decades. A great deal of variation in the methods of preparation of autologous serum eye drops, the end concentration and the duration of use exists in published literature. In this review, simplified recommendations for preparation, transport, storage and use of autologous serum are described. Evidence for the use of this modality in aqueous deficient dry eye disease is summarized, along with expertise-based rationale.
