Diving after a CRVO
About 18 months ago I suffered a CRVO in my left eye. I am healthy and fit 40 year old and despite numerous tests the doctors have not been able to find out why this happened. I do not have ay of the normal risk factors such as diabetes, high blood pressure etc. The CRVO healed itself after 6 months and I now have 90% of my vision back in the affected eye.

I hadnít dived for a year before the incident and havenít dived since. My question is therefore whether diving again will increase the risk of a CRVO reoccurring. Much as Iíd like to dive again, I value my eyesight more than my recreational diving so if there was any risk at all I would like to know.

Thanks for the query - a difficult one.

Despite extensive searching there's very little data I can find on this, so what I say is largely empirical. There's no obvious reason that diving should increase the risk of another CRVO per se. As long as the obvious risk factors have been excluded (high BP, diabetes, smoking, obesity etc.) then I don't see a problem with future diving.

Hope that helps

Regards, Dr O
