Abstract

Aim: To find retinal nerve fibre layer (RNFL) changes following scleral buckling (SB) for rhegmatogenous retinal detachment (RRD) with proliferative vitreoretinopathy (PVR) upto C2.

Methods: 40 RRD patients, aged 18-65 years were enrolled for SBS. Multivariate linear regression used multiple independent variables to predict value of dependent variable i.e. change in RNFL thickness following SB.

Results: The pre-surgery RNFL thickness of 108.5820.38m reduced to 103.7317.98m (p=.04; SS) after SB. Change in- axial length (p=.04), ganglion cell complex (GCC) focal loss of volume (p=.04), gross loss of volume (p=.007) and retinal nerve fibre layer temporal (p=.001) brought about SS change in RNFL thickness following SB. No SS association was found between buckle parameters with post-operative RNFL thickness. The PVR status C2 had worst RNFL thickness (P=.04) as compared to PVR A, B or C1.

Conclusions: The RNFL thickness reduction was associated with GCC loss and higher grades of PVR.
