Abstract: :
Purpose: To compare the influence of partial versus complete posterior vitreous detachment (PVD) on the outcomes of pneumatic retinopexy (PR), scleral buckling (SB), and pars plana vitrectomy (PPV) for phakic primary rhegmatogenous retinal detachment (RD). Methods: A prospective study of sixty eyes evaluated the PVD status in phakic RDs with flap tears. Pre–operative B–scan ultrasonography was used to separate eyes into two groups: partial or complete PVD. The surgeon was masked to the PVD status. Primary and final anatomical success, reoperation rates, and final visual acuity (VA) were compared. Results: Fifty eyes completed 12 months of follow–up. The primary success of PR was 33.3% in the partial PVD and 89.9% in the complete PVD group (p= 0.02). For SB, it was 50.0% in the partial PVD and 100% in the complete PVD group (p= 0.05). For PPV, it was 100% in the partial PVD and 91.7% in the complete PVD group (p= 0.70). The final success was 100% for both groups. The reoperation rate was 45.5% for partial and 7.1% for complete PVD (p< 0.01). Final VA was similar for both groups. Conclusions: Complete PVD seems to be associated with a higher primary success rate than partial PVD in eyes with phakic RD with flap tears undergoing pneumatic retinopexy and scleral buckling. With pars plana vitrectomy, PVD status didn’t seem to interfere with the primary success rate.
