How a strong blow to the head might cause a retinal detachment?

A strong blow to the head can cause a retinal detachment by creating sudden acceleration and deceleration forces that may pull the retina away from the underlying tissue. This trauma can lead to tears or breaks in the retina, allowing fluid to seep underneath and separate it from the retinal pigment epithelium. The impact can also cause direct damage to the eye structures, increasing the risk of detachment. Prompt medical evaluation is crucial after head injuries to prevent vision loss.
