Purpose. To compare the stages of vitreous degeneration in patients with vitreomacular traction (VMT) and macular holes (MH). Methods. A retrospective study was performed analyzing stages of vitreous degeneration of eyes with VMT or MH using swept-source optical coherence tomography (SS-OCT) and spectral-domain optical coherence tomography (SD-OCT). An analogous review was performed on a contro...

Two hereditary syndromes characterized by the association of retinal changes and erythrocytic anomalies have been described: (1) Retinopathy complicating haemoglobin anomalies, thalassaemia (Rudd, Evans, and Peeney, 1953), or sickle-cell anaemia (Lieb, Geeraets, and Guerry, 1959); (2) Atypical retinitis pigmentosa with thorny erythrocytes (acanthocytosis: Bassen and Kornzweig, 1950; Kornzweig a...

Knobloch syndrome is an autosomal recessive disorder associated with early-onset ocular abnormalities and central nervous system malformations. Ocular abnormalities are usually severe, and include high myopia, vitreoretinal degeneration, retinal detachment, macular abnormalities, and cataract. The most frequent systemic changes are midline malformations of the brain, ventricular dilation, and o...

During the last two to three decades, a large body of work has revealed the molecular basis of many human disorders, including retinal and vitreoretinal degenerations and dysfunctions. Although belonging to the group of orphan diseases, they affect probably more than two million people worldwide. Most excitingly, treatment of a particular form of congenital retinal degeneration is now possible....

With the dissemination of optical coherence tomography over the past two decades, the role of persistent vitreomacular adhesion (VMA) in the development of numerous macular pathologies - including idiopathic macular hole, vitreomacular traction syndrome, cystoid and diabetic macular edema, neovascularization in diabetic retinopathy and retinal vein occlusion, exudative age-related macular degen...

In 1904 and again in 1934, Gonin· de­ scribed the clinical characteristics of snail track degeneration of the retina. Sharply de­ marcated bands of white, crinkled, or frost­ like change of the inner retinal surface (Figs. 1 and 2) create a picture that is remi­ niscent of the tracks made by a snail; this appearance led to the descriptive naming of this entity. Several authors have commented on...
