La drépanocytose est une maladie systémique hématologique induisant la survenue d'événements vaso-occlusifs de divers organes cibles. Sur le plan oculaire, l'atteinte rétinienne se caractérise par des occlusions préférentiellement artérielles et de la vascularisation terminale, pouvant se compliquer de néovascularisation périphérique. Longtemps ignorée, la maculopathie drépanocytaire est désormais bien caractérisée grâce à l'imagerie multimodale[. Une] étude de cas suggère que la maculopathie drépanocytaire, caractérisée par des amincissements rétiniens focaux, proviendrait d'une ischémie du plexus capillaire rétinien profond, à l'origine d'une atrophie tissulaire séquellaire.
