Pharmacological vitrectomy refers to the use of enzymes in an effort to liquefy vitreous and to weaken the adhesion of vitreous cortex to the internal limiting membrane during or before performing vitreous surgery. It is well known that the vitreoretinal interface plays important roles in developing many blinding diseases.

Results of 110 Vitrectomies with a Portable Vitrectomy System
American Journal of Ophthalmology, 1983We retrospectively evaluated the VITAC (vitreous-tissue aspiration cutter), a portable vitrectomy system with an end-cutting vitrectomy probe with a self-sharpening oscillating blade and a monoblock design, in 110 vitrectomy procedures, 34 performed at the University of California Davis Medical Center and 76 performed at the Eye and ENT Hospital in ...

RETINA, 1981
The histopathologic and cytopathologic study of ocular fluids obtained for diagnostic purposes is presented. The analysis of fluid specimens with millipore filter, celloidin bag-cell block, and transmission electron microscopy techniques has proved to be effective for establishing and confirming clinical diagnoses.

Current Opinion in Ophthalmology, 1994
Proliferative diabetic retinopathy is one of the leading causes of permanent vision loss. Vitrectomy for the complications of proliferative changes has resulted in preservation of vision. Recent studies have focused on the cellular and structural changes in patients with proliferative changes.

Pars plana vitrectomy (PPV) in cases of uveitis can be used for diagnostic as well as therapeutic purposes. Generally accepted indications for diagnostic PPV include atypical uveitis that responds poorly to conventional therapy, suspected infectious endophthalmitis, or suspected intraocular malignancy.

[Vitrectomy and endophthalmitis].
Journal francais d'ophtalmologie, 2008The decision to perform a vitrectomy in a case of endophthalmitis is mainly based on the Endophthalmitis Vitrectomy Study (EVS) conclusions. An emergency vitrectomy is helpful when the baseline visual acuity is lower than hand motion perceptions.

VITRECTOMY IN ASTEROID HYALOSIS
Retina, 1990Asteroid hyalosis (AH), a condition in which calcium-lipid complexes form in the collagen meshwork of the vitreous, affects from 0.5% to 0.9% of the general population. In patients with dense AH and visual loss, obscuration of fundus detail on ophthalmoscopy and even on fluorescein angiography may complicate the diagnosis and treatment of underlying ...

Pars Plana Vitrectomy with the 25 + Vitrectomy System [PDF]
, 2014 The 25+ vitrectomy system was developed with the aim to make vitrectomy a safer, simpler and faster procedure. In our Department, this innovative technique became available in 2011 and since then, we use it exclusively in our cases. The purpose of this paper is to present the outcomes of 25+vitrectomy in various ocular diseases.
