OBJECTIVE: To identify cases of non-ischemic @entity2994 ( @entity2994 ) presenting as isolated patchy perivenular retinal whitening and to describe diagnostic considerations and short-term natural history. MATERIAL AND METHODS: Retrospective observational monocentric case series. @entity1 monitored in one center between January  2013  and January  2015. Among the 151  @entity1 monitored in our center for @entity2994 , we identified @entity1 presenting with isolated patchy perivenular whitening revealing @entity732 . RESULTS: Eight @entity1 presenting with isolated perivenular whitening revealing @entity2994 were identified (3.9  %). There were five central @entity2994 , three @entity2994 and no branch @entity2994 . Initial visual acuity was preserved in five out of eight cases. In all cases, patchy perivenular whitening was isolated, without @entity5861 . Blue monochromatic photographs allowed visualization of patchy perivenular whitening in all cases. Optical coherence tomography (OCT) showed a focal and segmental hyper-reflective area in the inner @entity2479 , especially in the inner nuclear layer. One month after diagnosis, @entity194 was noted in the @entity2479 showing @entity1613 . Three cases of our series of eight were initially mistakenly diagnosed as central retinal @entity432 . CONCLUSION: The main complication of perivenular whitening is the @entity194 of inner @entity2479 responsible for paracentral @entity1019 . The differential diagnosis with retinal @entity432 , which may be difficult, is based on the angiographic and OCT features, and their progression.
