Titre | Pneumatic release of focal vitreomacular traction |
Abstract Nr. | 1050 |
But | To study the efficacy of a single intravitreal injection of expansile gas as a valuable alternative to current treatment options (conservative, pharmacological and surgical) in patients with symptomatic, focal vitreomacular traction (VMT). |
Méthodes | Twenty eyes in 17 patients with symptomatic and persisting focal VMT were treated in an outpatient setting with an intravitreal gas injection of 0.2mL. In nineteen eyes 100% hexafluoroethane (C2F6) was used. One eye received sulfur hexafluoride (SF6). To all but three patients posturing advice was given. Patients were reviewed with a full eye examination and ocular coherence tomography (OCT) after 14 days and later. The primary outcome measure was the release of VMT on OCT. |
Résultats | In 17 of 20 (85.0%) of treated eyes a release of VMT was achieved as documented on OCT. The release of VMT was diagnosed during the first month after injection in 11 eyes of 11 patients and within 3 months in 16 eyes of 15 patients. In all but 5 of our patients best corrected visual acuity (BCVA) remained stable or improved. In 4 patients the progression or development of cataract was the probable cause of the decrease of BCVA. One patient developed a stage II macular hole after injection and needed vitrectomy. None of the treated patients developed retinal breaks. |
Conclusion | Intravitreal expansile gas injection could offer a minimally invasive, low-cost alternative treatment in patients with symptomatic, persisting VMT. Additional studies on a larger number of patients are required. |
