title: [Optical coherence tomography macular study on eyes filled with silicone oil].
abstract: OBJECTIVE
  To demonstrate optical coherence tomography efficacy to evaluate macular anatomical outcomes, in eyes with silicone oil-filled vitreous cavity after vitrectomy.
  
  
  METHODS
  A descriptive observational study of 28 (twenty-eight) patients submitted to pars plana vitrectomy having silicone oil as vitreous substitute. The macular findings were observed by means of indirect binocular ophthalmoscope, biomicroscopy and optical coherence tomography examinations.
  
  
  RESULTS
  During the follow-up period the retina remained attached in all patients. In some cases, intraretinal cysts, epiretinal membrane and lamellar macular hole were observed only by optical coherence tomography examination.
  
  
  CONCLUSIONS
  Optical coherence tomography provided improved imaging of finer retinal structures in eyes with silicone oil-filled vitreous cavity. Therefore, optical coherence tomography examination should be systematically performed in eyes filled with silicone oil to recognize changes in retinal morphology.
