title: Juxtapapillary subretinal pigment epithelial polypoid pseudocysts associated with unilateral tilted optic disc: case report with clinicopathologic correlation.
abstract: OBJECTIVE
  To describe the unique preoperative appearance, successful postoperative clinical course, and histopathologic features of a cluster of progressively enlarging pseudocysts that arose at the temporal margin of a unilateral tilted optic disc.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Clinical observation, color fundus photography, fluorescein angiography, and optical coherence tomography, as well as routine histologic and immunohistochemical studies of tissue removed by subretinal surgery.
  
  
  RESULTS
  Subretinal surgical excision of the lesions resulted in retinal reattachment with improved postoperative visual acuity. Histologic examination disclosed a cluster of fluid-filled polypoid pseudocysts lined by small vessels of choroidal origin lying beneath the basement membrane of the overlying retinal pigment epithelium (RPE).
  
  
  CONCLUSIONS
  We postulate that buds of small vessels of choroidal origin grew through or around the edge of Bruch's membrane at the temporal margin of the tilted optic disc and then passed under the juxtapapillary RPE. Ensuing leakage of proteinaceous fluid from these vessels eventuated in formation of a cluster of polypoid pseudocysts and subsequent localized papillomacular retinal separation with visual loss. The lesions were amenable to subretinal surgical removal with restoration of visual acuity.
