Proliferative vitreoretinopathy: current and emerging.
View This Abstract Online; Proliferative vitreoretinopathy: an overview. Surv Ophthalmol. 1998; 43(1):3-18 (ISSN: 0039-6257). Pastor JC. Proliferative vitreoretinopathy (PVR) is still the most common cause of failure of surgery for rhegmatogenous retinal detachment, despite the substantial effort that has been devoted to better understanding and managing this condition during the past 25 years.
Etiology varies with the nature of the RD. The condition of the vitreous is an extremely important factor leading to rhegmatogenous RD. Syneresis, where the normal gel structure gives way to a mixture of gel and fluid, allows the available nonbound or free water to access the subretinal space through any retinal break, leading to RD.
A new classification of ocular trauma The need for a standardized system in ocular trauma terminology Highly successful class ifications have been created for retinopathy of prematurity ( 17) and proliferative vitreoretinopathy ( 18), but the field of ocular trauma is still in need of a standardi zed nomenclature.
For example, one study reported 1.5% of all diabetics developed proliferative retinopathy in 5 years, compared to 4.2% of those with existing non-proliferative retinopathy. An estimated 1.2% of the diabetic population develop sight-threatening disease each year, which may be either proliferative retinopathy or, more commonly, macular oedema.
To provide an update on current surgical techniques and emerging medical management in proliferative vitreoretinopathy (PVR). Methods: A literature search was conducted on studies in the past decade with the inclusion of historical, landmark studies.
Retinal detachment is a disorder of the eye in which the retina separates from the layer underneath. Symptoms include an increase in the number of floaters, flashes of light, and worsening of the outer part of the visual field. This may be described as a curtain over part of the field of vision. In about 7% of cases both eyes are affected. Without treatment permanent loss of vision may occur.
Proliferative vitreoretinopathy (PVR) is the most common cause of failure in retinal detachment surgery. It can occur in untreated eyes or occur after pneumatic retinopexy, cryotherapy, laser retinopexy, scleral buckling, or vitrectomy.
