Proliferative vitreo-retinopathy (PVR) was defined as formation of a membrane on the vitreous face
and surface of the retina due to abnormal proliferation of cells which causes puckering and retraction of the retina.
The complications which occurred in this study are Raised IOP, IOL Pitting and Rupture of the Anterior Vitreous Face
Additionally positioning lens closer to the rotational center of the eye just anterior to the vitreous face
may reduce the centrifugal forces on the lens and stabilize the ocular contents thereby decreasing the probability of complications such as iritis cystoids macular edema (CME) and retinal detachment.
Frequency of YAG laser complications was raised intraocular pressure in 25(10%) patients, IOL damage in 30(12%), rupture of anterior vitreous face in 13(5.
The possible complications associated with this procedure are elevation of intraocular pressure, rupture of anterior vitreous face, damage to intra ocular lens, acute iritis and cystoid macular edema (CMO).
This occurs from tangential traction caused by anterior to posterior contraction of the vitreous face
at the macula.
Up to one quadrant of subretinal fuid may be present Group E -- very high risk Eyes that have been destroyed anatomically or functionally by the tumour Eyes with one or more of the following: irreversible neovascular glaucoma, massive intra-ocular haemorrhage, aseptic orbital cellulitis, tumour anterior to the anterior vitreous face
, tumour touching the lens, difuse infltrating retinoblastoma, phthisis and pre-phthisis
Positioning lens closer to the rotational center of the eye, just anterior to the vitreous face
, may reduce the centrifugal forces on the lens and stabilize the ocular contents, thereby decreasing the probability of complications such as Iritis, Cystoid macular edema (CME) and Retinal detachment.
Indeed, it is the nonseparation of a contracting vitreous face
, leading to tangential traction across the fovea that is thought to be the cause of the condition.
INTRODUCTION: Pharmacologic Vitreolysis: Vitreoretinal interface is involved in a wide range of vitreoretinal disorders and separation of posterior vitreous face
from retinal surface is an essential part of vitrectomy surgery.
These are easily and successfully treated by lysing the vitreous face
, in a similar manner to YAG capsulotomy for treatment of posterior capsular opacification (PCO).
Sometimes the posterior vitreous face
can be seen 'flapping' in the vitreous when the patient moves their eye, but this can sometimes be difficult to tell in ageing vitreous gel from other vitreous floaters.
