TL;DR: Unifying the spectrum of vitreo-retinal diseases into the conceptual framework of APVD underscores that to more effectively treat, and ultimately prevent, these disorders it is necessary to replicate the two components of an innocuous PVD, i.e., gel liquefaction and vitreoschisis.
Abstract: Posterior vitreous detachment (PVD) is the consequence of changes in the macromolecular structure of gel vitreous that result in liquefaction, concurrent with alterations in the extracellular matrix at the vitreo-retinal interface that allow the posterior vitreous cortex to detach from the internal limiting lamina of the retina. Gel liquefaction that exceeds the degree of vitreo-retinal dehiscence results in anomalous PVD (APVD). APVD varies in its clinical manifestations depending upon where in the fundus vitreo-retinal adhesion is strongest. At the periphery, APVD results in retinal tears and detachments. In the macula, APVD causes vitreo-macular traction syndrome, results in vitreoschisis with macular pucker or macular holes, or contributes to some cases of diabetic macular edema. At the optic disc and retina, APVD causes vitreo-papillary traction and promotes retinal and optic disc neovascularization. Unifying the spectrum of vitreo-retinal diseases into the conceptual framework of APVD underscores that to more effectively treat, and ultimately prevent, these disorders it is necessary to replicate the two components of an innocuous PVD, i.e., gel liquefaction and vitreo-retinal dehiscence. Pharmacologic vitreolysis is designed to mitigate against APVD by chemically breaking down vitreous macromolecules and weakening vitreo-retinal adhesion to safely detach the posterior vitreous cortex. This would not only facilitate surgery, but if performed early in the natural history of disease, it should prevent progressive disease.

TL;DR: Primary PPV with fluid-gas exchange and laser is a safe, effective method to repair primary pseudophakic retinal detachments and the anatomic reattachment rate and the visual acuity obtained with this technique appear to be at least as good as those reported in the literature for scleral buckling,PPV with sCleral bucking, and pneumatic retinopexy.

TL;DR: This article will review these complications of high myopia and discuss the current concepts relating to these complications and their treatments, hoping this information will be helpful for the daily practice of treating myopic eyes.
Abstract: High myopia is very common and one of the major causes of social blindness, especially in East Asian countries. It is characterized by axial length elongation, and induces various specific complications, including cataract formation, retinal detachment from peripheral retinal tears, myopic foveoschisis, macular hole with or without retinal detachment, peripapillary deformation, dome-shaped macula, choroidal/scleral thinning, myopic choroidal neovascularization, and glaucoma. This article will review these complications and discuss the current concepts relating to these complications and their treatments. Conclusion This information will be helpful for the daily practice of treating myopic eyes.

TL;DR: No statistical relationship was found between either anatomic success or functional result and the presence of aphakia, demarcation lines, vitreous hemorrhage, detachments of the pars plana epithelium, or predetachment glaucoma being treated.

TL;DR: Three low-viscosity perfluorocarbon liquids provided an intraoperative tool during vitrectomy to manage giant retinal tears and complement present surgical techniques for managing giant Retinal tears.
Abstract: • Three low-viscosity perfluorocarbon liquids provided an intraoperative tool during vitrectomy to manage giant retinal tears. These clear fluids have a high specific gravity (1.8 to 1.9) and are immiscible with water. In six eyes, the giant tear was less than 180°; in 11 eyes, it was 180° or greater. In all eyes, the tear was unfolded and the retina was flattened while the patient was supine. The perfluorocarbon liquid was aspirated and replaced by air-perfluorocarbon gas mixtures (16 eyes) or silicone oil (one eye) at the end of the operation. The retina was reattached in 16 eyes (94%), with a minimum follow-up period of 6 months. In five eyes (29%), the retina was reattached without scleral buckling. Residual droplets of perfluorocarbon liquid were observed in four patients. These new materials complement present surgical techniques for managing giant retinal tears.
