[Optical coherence tomography macular study on eyes filled with silicone oil].

Purpose: 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.

Conclusion: 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.
