Abstract
Long standing rhegmatogenous retinal detachment is complicated with development of PVR which
is defined as the growth and contraction of cellular membranes within the vitreous cavity and on
both surfaces of the retina. Despite of the recent surgical advances, PVR is still the leading
cause of failure of retinal detachment surgery. Management of the RRD complicated with PVR
includes meticulous epiretinal and subretinal membrane dissection and the relieve of all
traction on the retina. In many cases despite of this, the retina will remain for shortened to the
point that
it can not be reattached to the underlying RPE. In such cases relaxing retinotomies and.
retinectomies are needed. So, the decision to perform a retinotomy/retinectomy should be taken only
after all attempts that have been made to release traction on the retina through dissection. So, it
is an intraoperative decision and it is the procedure of last resolt when other methods fail to
reattach the detached retina.
Complications of relaxing retinotomies and retinectomies may be serious and may result in some
decline in the visual functions. However, with appropriate management, cases that have been
previously lost can now obtain some useful visual functions.
We conducted our study on 50 eyes of 50 patients with RRD complicated with grade C PVR
from patients attending Minia University
Hospital
to undergo
pars
plana
vitrectomy, relaxing
retinotomies/retinectomies and long acting tamponade using silicone oiL
By the 6 month postoperative period we obtained retinal attachment in 82% of cases and
improvement of the visual functions in about 34% of cases and it is reasonably a good percentage.
Finally we can conclude that relaxing retinotomies and
A \ v’
retinectomies can stand hand by hand’-’Vwith p”’assive membrane dissection in the management ofRRD
complicated with PVR.
And we recommend the following:
• Long term follow-up period.
• The use of triamcinolone actenoid for better visualization and good dissection of membranes.
• Investigations to inhibit the cellular proliferation, especially in the area of
pharmacologic therapy which may prevent the recurrence of intra-ocular proliferation with is the
most common problem after relaxing retinotomies and retinectomies.
