Retina / Choroid Disorders
Rhegmatogenous retinal detachment demonstrating a flap tear with one bridging vessel and a posteriorly rolled edge. The irregular retinal folds are caused by mild proliferative vitreoretinopathy (PVR).

  • The most commonly seen retinal detachment.
  • Usually there is/are retinal break(s) induced by posterior vitreous detachment.
  • Fluid from liquefied vitreous can pass through the break(s), enter the potential subretinal space and undermine the retina from the RPE.
  • Signs:
    • Retinal break(s)
    • Undulating bulla, retinal tear flap, or corrugated folds
    • Pigment in vitreous (tobacco dusts)
    • Syneretic vitreous (liquefaction changes within the corpus vitreous)
    • Low intraocular pressure
  • Management: Identify and treat the breaks by a number of methods such as:
    • Scleral buckling, cryotherapy or laser to promote firm chorioretinal adhesion.
    • Pneumatic retinopexy for selected superior detachment.
    • Temporary balloon device as a temporary buckling.
    • Vitrectomy.
