Title: Dome-shaped detachment of premacular vitreous cortex in macular hole development. Author: Mori K, Abe T, Yoneya S. Journal: Ophthalmic Surg Lasers; 2000; 31(3):203-9. PubMed ID: 10847496. Abstract: PURPOSE: To clarify the role of the posterior vitreous cortex in macular hole development, we evaluated the follow-up findings of clinical observations and optical coherence tomography (OCT) images of macular holes in early stage. METHODS: The vitreoretinal tomography was examined and followed in eyes with stage 1 and 2 macular holes with OCT. RESULTS: The posterior cortical vitreous was identified in 12 of 17 eyes with early-stage macular holes by OCT (71%). In these eyes, the detached posterior vitreous appeared to be merged to the fovea and the disc. The vitreoretinal separations showed typically dome-shaped. A long scan along the papillomacular axis also delineated the posterior vitreous face as dome-shaped perifoveal vitreous detachment with adhesion to the fovea and disc. Repetitive OCT examinations clearly demonstrated the course of development of the macular hole. CONCLUSIONS: The dome-shaped vitreoretinal separation seen with OCT gives rise to an idea that the posterior vitreous cortex may not be taut but slack, and would not cause a continuous tractional force even in early-stage macular holes. This finding brings us an idea that the tangential traction at the fovea may be generated by fluid movements, rather than by contraction of the cortical vitreous.[Abstract] [Full Text] [Related] [New Search]
