Diagnosis and Treatment of Vitreomacular Traction Syndrome Using Optical Coherence Tomography

ABSTRACT

PURPOSE: To determine the benefit of optical coherence tomography (OCT) in the diagnosis of vitreomacular traction syndrome and evaluate the vitreoretinal interface before and after vitreous surgery. METHODS: Medical records of five patients with vitreomacular traction syndrome who had undergone vitrectomy were reviewed. Preoperative and postoperative visual acuity and preoperative and postoperative OCT were reviewed. In all patients OCT demonstrated posterior vitreous detachment and a focal adhesion of hyaloid membrane to macula with traction on the foveal retinal tissue. All of them underwent pars plana vitrectomy with peeling of poterior hyaloid face. RESULTS: Visual acuity improved in 4 eyes after the first vitrectomy. One eye developed postoperatively a macular hole, which was treated with the second vitrectomy and intravitreal gas tamponade with subsequent improvement in vision. In 4 eyes, OCT showed elimination of vitreous strand, relief of vitreous traction and restoration of normal foveal contour after vitrectomy. CONCLUSION: Optical coherence tomography is a useful tool in the diagnosis of vitreomacular traction syndrome and in the evaluation of status of vitreoretinal interface before and after vitrectomy. Following pars plana vitrectomy, vision improved and normal foveal contour was restored.
