The study aims to review the efficacy of scleral buckling and vitrectomy
in the management of cases of advanced PVR (grades C and D) according
to the Retina Society Classification System). Sixty cases of total
retinal detachment complicated by the more advanced grades (grades C
and D) of PVR were treated with sclera' buckling alone (24 eyes) and vitrectomy
and internal tamponade (36 eyes). The overall success rate of
the scleral bucking-treated eyes was 57.6%, and in the vitrectomytreated
eyes was 70.5%. Of the anatomically successful cases, 89.7%
achieved a final visual acuity of counting fingers or better. The major
causes of surgical failure were redetachment from persistent vitreoretinal
traction (15.5%) and intraoperative complications (11.6%). Conclusion:
Scleral buckling alone should be considered as the primary surgical procedure
in selected cases of PVR characteristically, grade-C. In more advanced
cases vitrectomy combined with internal tamponade might offer a
better result. |
