Major pathophysiological factors include abnormal anatomic relationships between ciliary processes, the crystalline or intraocular lens, and the anterior vitreous face
[3,12,13], abnormal permeability of the anterior hyaloids [3,7], expansion of choroid , or anterior rotation of the ciliary body .
An epiretinal membrane (ERM) is a sheet of fibrous tissue that forms in between the vitreous face
and the internal limiting membrane of the retina presenting with a wrinkled or puckered cellophane appearance (see Figure 7).
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.45 Another advantage of positioning the lens closer to the nodal point and center of the eyes is the superior optical properties of the lens in this position.
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(5.5%), anterior uveitis in 20(8%), cystoid macular edema in 20(8%) and retinal damage in 5(2%).
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.
For some delegates, currently not allowed to use diagnostics in their own countries, this was the first time they had ever seen the anterior vitreous face
with a slit lamp.
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.
This occurs from tangential traction caused by anterior to posterior contraction of the vitreous face
at the macula.
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.
