• recent XLRS published studies

• Recently there have been two studies published on XLRS that interest me:
  
  The first study: Most gene replacement therapies utilize a virus vector to "infect" a patient's DNA with the correct copy of a gene. Researchers in Spain have developed a delivery system that does not require the use of a viral vector. They used the technology on a rat model of XLRS with promising results. What is especially exciting is that they found that even topical use could possibly be effective. What if they are able to develop eye drops to correct retinal genetic defects?
  
  See the study abstract here:

  The second study: Researchers in China compared XLRS patients who have vitrectomies to those who have not. They concluded that "Vitrectomy may be an effective and essential treatment for patients with progressive X-linked retinoschisis to prevent a deterioration of vision before severe complications developed in their eyes." I want to ask my doctors what they think about performing vitrectomies prophylactically. Would performing a vitrectomy before there are complications help preserve vision and prevent future complications? Has anybody else asked their doctors about this?
