[Probability of successful operation in very severe retinal detachment using scleral buckling procedure]

The aim of this study was to study the efficacy of operation of scleral invagination in the treatment of very severe retinal detachment with proliferative vitreoretinopathy (PVR). The investigations comprised 36 eyes operated in the Department of Ophthalmology in Krakow in the period 1986-1990. The authors performed in 24 patients a encircling operation with a silicone band, in 12-meridional or parallel extrascleral silicone sponge implants. Reattachment of the retina was achieved in 58 p.c. of eyes and an improvement of the visual acuity in 47 p.c. The performed analysis showed a substantial dependence of the attained effect of surgery on the grade of advancement of the PVR; it enabled to ascertain that the limit of possibilities of the scleral buckling procedure determines PVR stadium C3.
