Abstract
AIM: To demonstrate the ultrastructure of vitreomacular traction associated with persistent hyaloid artery. METHODS: Pars plana vitrectomy was performed in a 66-year-old man with progressive vitreomacular traction associated with a persistent hyaloid artery. Epimacular tissue was peeled and processed for transmission electron microscopy. RESULTS: Ultrastructural analysis revealed multiple sheets of cellular and collagenous components. Myofibroblasts and newly formed collagen were the predominant features. Fibrous astrocytes, fibroblasts, macrophages, and basement membrane were also present. CONCLUSION: The cellular composition of the epimacular tissue and high cellular activity suggest that persistence of the hyaloid artery may contribute to the development of vitreomacular traction.
