A retinal detachment that changes the color of what you see is often difficult to recover from. Retinal detachment causes seeing things in color, mainly because the extent of retinal detachment involves the macular area, which affects the visual function. The vision of feeling color is mainly cone cells, which are distributed in large numbers in the macula. Therefore, when the retina is detached from the macula, it will affect the patient’s color recognition. Even when the detached retina is surgically flattened, the impaired visual function is often difficult to restore. This type of retinal detachment involving the macula is often treated with vitrectomy + vitreous cavity filling surgery to preserve as much vision as possible, as well as some visual function, and to prevent worsening of the lesion and eventual blindness.
