Vitrectomy describes an eye surgery in which parts of the vitreous humor (i.e., the gel-like mass inside the eye) are surgically removed. This occurs, for example, in advanced diabetic retinopathy with retinal detachment or persistent vitreous hemorrhage. Furthermore, vitreous opacities may still be bothersome after laser vitreolysis. Also in this case then vitrectomy can help. In cases where there is vitreous opacification, the cause of which is unknown, this operation can also be used excellently.
In case of inflammatory changes, the vitreous samples are examined bacteriologically, cytologically and virologically after removal. Retinal detachments with holes in the retina or epiretinal gliosis are also taken care of by vitrectomy. In case of eye injuries or removal of foreign bodies from the eye, vitrectomy is used in combination with antibiotic administration.
The operation is performed under local anesthesia or general anesthesia, during which the mobility and perception of pain in the eye is switched off for a short time. Depending on the severity, the operation lasts between 30 and 60 minutes.
