Generally speaking, in my opinion, scuba diving can not lead to retinal detachment. So there is nothing you need to worry about. Well, acully there are many factors which can lead to retinal detachment, such as eye injury, severe high blood pressure. But on the other hand, most people with detached retina risk factors will not develop a detached retina. And it is possible that people without risk factors will develop a retinal detachment. Of course, if you go and have the diving, I will suggest you should be careful about your eyes, so that you can not get hurt or have infection by it. Also, If you have some questions about retinal detachments, you can talk with your doctor. He or she can recommend detached retina symptoms to watch for and a schedule for regular eye exams.
