Comments and Conclusions

  • SD OCT can provide evidence of both photoreceptor loss and RNFL loss in the same eye and help diagnose two apparently unrelated disorders.
  • Although both the fundus albi and the cone dystrophy appear to be non-progressive or very slowly progressive, undetected glaucoma can progress and lead to blindness If untreated.
  • The differential diagnosis includes other disorders with night blindness, especially retinitis punctata albescens or RP with white dots.8
  • Unlike our patient with FA, patients with RP do not demonstrate normal or near normal ERGs after several hours of dark adaptation. In addition, RP is virtually always progressive.8
