- Most common cause of failure in retinal reattachment surgery
- Characterized by the formation of cellular membrane on both surfaces
of the retina and in the vitreous
- Predisposed by retinal break
- Contraction of the cellular membranes lead to tractional and rhegmatogenous
retinal detachments
- Clinical features:
- Symptoms: loss of vision especially with extensive PVR involving
the macula
- Signs:
- Retinal break
- Diffuse vitreous haze, pigment clumps or clusters on the
retina
- Wrinkling of inner retina, retinal stiffness associated
with decreased mobility of the vitreous
- Full thickness, fixed folds which may be located posterior
or anterior to the equator.
- The severity is expressed by the number of clock hours involved
in the proliferations
- Condensed vitreous strands
- Management:
- Scleral buckling to close the retinal breaks in mild PVR
- Surgical relief of traction
- Retinopexy for stabilization of reattached retinal breaks
