My son has Juvenile X-Linked Retinoschisis. We discovered he had it at age 1.5 when one eye sort of turned in toward the nose. Both eyes are affected.
Treatment is basically an attempt to stop the blisters from advancing on the macula.
Vitrectomy with membrane peeling and laser demarcation was performed initially. Unfortunately, it was not effective for my son. He suffered several severe detachments involving the macula post operatively. His other eye is affected, however only the peripheral areas. I am told that the older the kids get, the more stable the retina.
