Hi. I'll be happy to help you with your question.
As you know X-linked juvenile retianoschisis (xljrs) causes splitting of your retina at the level of the nerve fiber layer. A reduction in vision is observed from about age 4 until about age 20, at which time it usually becomes stable.
Then, around age 50 or 60 the vision starts to get worse again with the onset of macular damage. The final vision is usually in the 20/100 range.
I see you are online. Do you know if you have peripheral retinal schisis cavities?
my brothers and i still fluctuate quite a bit my oldest brother 31 has just stabalised yes
and how danferous is it for me if i get hit like in sports or boxing
It is rare for xljrs to cause retinal detachment although, in patients with large peripheral retinal schisis cavities might be a slightly higer risk of a detachment when compaired to patients without them
I guess that is the doctor way of saying you should be fine doing sports, although I wouldn't recommend that you let Mike Tyson hit you in the head!
Retinal diseases is an interest of mine, although I am not a retinal specialist. What else can I answer for you?
Are you still there?
