[Results of transpupillar vitrectomy (author's transl)]. 1977

W Böke, and K Dannenberg

Vitreous prolapse in cataract surgery or during the extraction of a dislocated lens; corneal dystrophy in aphacic eyes due to corneo-vitreous contact and vitreous invading the anterior chamber following perforating injury proved to be valid indications for partial transpupillary vitrectomy. In malignant glaucoma, in postoperative wound rupture following cataract extraction, in open-sky-surgery of the anterior segment of aphacic eyes and in other particular conditions, transpupillary vitrectomy may also be considered. The transpupillary approach is not indicated in retinal detachment, unless prepupillary vitreous incarceration pulling up of the retina is obvious. Transpupillary vitrectomy can be performed without much harm to the eye even in children, if indicated (congenital cataract, congenital on traumatic lens dislocation, perforating lens injury). In general the results of transpupillary vitrectomy are good. Longterm complications are relatively rare. Experiences on 208 eyes are reported in particular.

UI	MeSH Term	Description	Entries
D007908	Lens, Crystalline	A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.	Eye Lens,Lens, Eye,Crystalline Lens

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.

D011680	Pupil	The aperture in the iris through which light passes.	Pupils
D012163	Retinal Detachment	Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery.

D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
