Materials and Methods: A retrospective review of 21 patients who had undergone macular holes surgery with silicone oil tamponade was conducted The primary outcome variables include best-corrected visual acuity (BCVA) in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters and optical coherence tomography changes in eyes with a macular hole after the surgery.

Results: The median age of 21 patients was 58.32 years. Thirteen patients had Stage 3 macular holes and eight patients had Stage 4 macular holes. Anatomical closure rate was achieved in 90.4% (19/21) of all patients. The median preoperative BCVA was 31.2 ETDRS letters (range: 13-52 letters), which increased to 42.9 ETDRS letters (range: 27-74 letters), six weeks following the removal of the silicone oil.

Conclusion: Our study with 21 patients indicates that the use of silicone oil tamponade in macular hole surgery showed satisfactory anatomical and functional outcomes. As an alternative to gas tamponade, silicone oil can be used for primary macular hole surgery in patients that are unable to position themselves in a face-down posture after surgery.
