The vitreous surgery, also known as vitrectomy, involves complete removal of the vitreous, a clear gel that fills the back cavity of the eye, which is lined at the bottom of the retina.
the vitrectomy is performed through small incisions 3 in the rigid layer of the eye known as ladder. In these, of less than 1 mm each, two separate trucares through which the necessary instruments are inserted for intervention are placed. A trocar through a cannula infusion that keeps the ocular tone during the intervention is introduced. And through other trocars, a probe lighting and vitreotome is introduced, a tool that cuts and aspirates the vitreous. Other instruments, such as tweezers, scissors or laser are introduced when necessary for intervention.
The surgeon sees what is done through a microscope and special lenses that let you see inside the eye as he intervenes. Once removed the vitreous, leave the cavity leads to a buffer substance, which can be serum, air, expandable gases or silicone oil. Except the latter, substances are reabsorbed by the eye and replaced by serum produced by the eye itself. Any intervention is performed under local anesthesia.
Causes and Risks of vitrectomy
The causes for vitrectomy can be grouped into opacity loss caused by bleeding or opacity diabetes or infections on one side or access to intervene retinal pathologies affecting it, such as retinal detachment or diseases of the macula.
To this day, thanks to advances, vitrectomy involves no major complications. Following this intervention is common appearance of cataract, although it is solved by an intervention of this new pathology. Another risk is suffering from ocular hypertension after the intervention, that is solved with eyedrops. Although they may also arise more severe complications such as infection or retinal detachment.
Recovery after a vitrectomy
After submitting to an intervention of vitrectomy, the vision will be reduced and recovery anger from a few days in the milder pathologies, up to several months in more serious. The rest relative or absolute will be necessary in all cases.
