Vitrectomy
Vitrectomy is a surgery to remove some or all of the vitreous humor from the eye. Anterior vitrectomy entails removing small portions of the vitreous humor from the front structures of the eye—often because these are tangled in an intraocular lens or other structures. ''Pars plana'' vitrectomy is a general term for a group of operations accomplished in the deeper part of the eye, all of which involve removing some or all of the vitreous humor—the eye's clear internal jelly. Even before the modern era, some surgeons performed crude vitrectomies. For instance, Dutch surgeon Anton Nuck (1650–1692) claimed to have removed vitreous by suction in a young man with an inflamed eye. In Boston, John Collins Warren (1778–1856) performed a crude limited vitrectomy for angle closure glaucoma. Anesthesia for vitrectomy Options for anesthesia for vitrectomy are general anaesthesia, local anesthesia, topical anesthesia and intracameral lidocaine irrigation. Each anesthesia techn ...

Robert Machemer
Robert Machemer (16 March 1933 in Münster – 23 December 2009 in Durham, North Carolina) was a German-American ophthalmologist, ophthalmic surgeon, and inventor. He is sometimes called the "father of modern retinal surgery." Helmut Machemer, Robert's father, was an ophthalmologist who died in Ukraine on 18 May 1942, leaving a widow and three small sons. In 1953, when Robert Machemer completed his Abitur, he worked for six months in a steel mill to partially finance his medical school education. He studied medicine at the University of Münster, where he received his MD,Robert Machemer, MD , ASCRS (with video) and the University of Freiburg, where his received his [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macular Pucker
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes. Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD). PVD can create minor damage to the retina, stimulating exudate, inflammation, and leucocyte response. These cells can form a transparent layer gradually and, like all scar tissue, tighten to create tension on the retina which may bulge and pucker, or even cause swelling or macular edema. Often this results in distortions of vision that are clearly visible as bowing and blurring when looking at lines on chart paper (or an Amsler grid) within the macular area, or central 1.0 degree of visual arc. Usually it occurs in one eye first, and may cause binocular diplopia or double vision if the image from one eye is too different from the image of the other eye. The distortions ...
