Abstract: :
Purpose: To determine efficacy and visual and anatomic results of macular hole surgery using silicone oil tamponade. Methods: Eighty eyes of 79 patients with stage 2,3, or 4 primary or recurrent macular holes underwent pars plana vitrectomy, membrane peeling, and removal of internal limiting membrane (if prominent), followed by silicone oil tamponade for 6-12 weeks. Post-operative face-down positioning was maintained for one night. Results: Seventy-one eyes had primary holes and 9 eyes had recurrent holes. Follow-up ranged 6 to 36 months (median=15 months). Macular hole closed initially in 76 eyes (95%). In 4 eyes (5%), the macular hole re-opened after removal of silicone oil. Visual acuity improved 2 lines or more in 48 eyes (60%). Retinal detachment occurred in 2 eyes (2.5%). Four eyes (5%) required an additional operation to remove residual silicone bubbles. Cataract progressed in 80% of phakic eyes. Conclusion: Macular hole surgery using silicone oil tamponade provides an effective technique with excellent anatomic and visual results, minimal complications, and a much less stressful post-operative period for the patient.
