title: Intraretinal cyst secondary to longstanding retinal detachment.
abstract: OBJECTIVE
  To describe the diagnosis and management of an intraretinal cyst.
  
  
  METHODS
  A 34-year-old man with a history of retinal detachment presented sudden loss of vision in the left eye. Visual acuity was hand movement. Examination revealed hematic vitreous haze and ultrasound showed a rounded mobile object in the vitreous cavity.
  
  
  RESULTS
  After differential diagnosis ruled out cysticercosis, pars plana vitrectomy revealed a neovascularized intraretinal macrocyst attached to a posterior flap of a 13-year-old retinal tear. Retinotomy and retinectomy were performed, removing this cyst located in the upper retina together with a portion of detached retina. At 1 year, the retina had adapted and the vitreous cavity was clear. Final visual acuity was 18/20.
  
  
  CONCLUSIONS
  Intraretinal cysts are usually asymptomatic and associated with long-standing retinal detachment, as seen in our clinical case. Periodic fundus examination is essential for their detection. Surgical treatment of the underlying condition usually leads to complete resolution.
