چکیده مقاله:
Purpose: To describe a new technique in removing sub-macular hemorrhages (SMH) in traumatic patients and results in three patients. Methods: In this technique, for patients with SMH, a complete three port vitrectomy was performed. Using a back flush instrument and soft tip needle, considering safe distance from silicon tip to retina, SMH is swept using gentle flushes to a temporal site of the macula in which it removed via a retinotomy. In a case with macular hole, the hemorrhage is drained via the hole.Results: In case one, SMH was swept to the temporal of the macula and removed via a retinotomy. Best corrected visual acuity was improved from hand motion to 20/ 30. In the second patient, four weeks after trauma, SMH was removed and after three weeks the BCVA was improved to 20/25 after three weeks. In the third case that had macular hole, the SMH was drained via the MH and BCVA was improved from hand motion to 20/100. Conclusion: Sub-Macular hemorrhage sweeping using back flush after a complete vitrectomy seems to be efficacious in restoring macular anatomical and visual function.
