Retinal detachment refers to the separation between the neural epithelial layer and the pigment epithelial layer of the retina. Based on its cause, it can be categorized into rhegmatogenous retinal detachment, tractional retinal detachment, and exudative retinal detachment. Rhegmatogenous retinal detachment requires repositioning of the retina and closure of the break. If it is tractional retinal detachment, it is necessary to remove the cause, generally requiring vitrectomy and retinal reposition surgery. Exudative retinal detachment generally occurs due to inflammation or other irritations causing exudation or bleeding in the retina, resulting in detachment, typically without retinal breaks. This type of retinal detachment only requires treatment for the underlying disease, and aggressive treatment of the primary disease can generally lead to a cure. Therefore, retinal detachment must be treated; it cannot heal on its own.
