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. [1] In Boston, John Collins Warren (1778–1856) performed a crude limited vitrectomy for angle closure glaucoma. [2]
Proliferative vitreoretinopathy (PVR) is a disease that develops as a complication of rhegmatogenous retinal detachment.PVR occurs in about 8–10% of patients undergoing primary retinal detachment surgery and prevents the successful surgical repair of rhegmatogenous retinal detachment.
Retina Implant AG in Germany has also developed a subretinal implant, which has undergone clinical testing in nine patients. Trial was put on hold due to repeated failures.

A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina. [1] It refers to the separation of the posterior hyaloid membrane from the retina anywhere posterior to the vitreous base (a 3–4 mm wide attachment to the ora serrata ).

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).
