title: [Biomicroscopic observation of macular breaks].
abstract: Ninety-five eyes from 90 patients with macular breaks were studied biomicroscopically using the E1 Bayadi-Kajiura preset lens. Retinal detachments due to macular breaks were present in 14 of the eyes. The prevalence of posterior vitreous detachments (PVD) was 44% in idiopathic senile macular breaks (66 eyes), 78% in highly myopic macular breaks (9 eyes), and 95% in secondary macular breaks (20 eyes). Opercula, indicated the presence of vitreous traction, were found in 48% of the senile cases, in 22% of high myopes, and in 20% of secondary cases. Most of opercula were seen in eyes with no PVD or partial PVD. In 4 eyes without high myopia, vitreous traction at the edges of macular breaks resulted in retinal detachment.
