  1. Data are absolute vales (%), mean ± standard deviation (min-max), as appropriate.
  2. aocular pathologies that were noticed at all presentations
  3. b8 retinal images could be obtained by OCT/fundus photography; of these, 6 showed retinal degeneration on OCT (thinning of the outer layers); in 1 woman, macular edema was seen due to tapeto-retinal degeneration.
