Is there any evidence to suggest a link between strenuous exercise and Retinal Detachment or Posterior Vitreous Detachment?
I’m a -3.75 and due to my line of work (pilot), I’d like to minimise any risk to my vision.
No, there is NO conclusive evidence. Most RDs related to sports are from direct injuries to the eye.
Your biggest risk factor is being myopic (near sighted). A -3.75 is not too bad (not considered pathologic myopia) but you would be wise to make sure you have a yearly eye exam and it is by a doc who knows how to evaluate your peripheral retina (looking for “weak areas” and/or retinal breaks).
