To evaluate the additional effect of scleral buckling (SB) to pars plana vitrectomy and to compare the properties of the vitreous base and retinal tears in uncomplicated primary phakic rhegmatogenous retinal detachment (prd group) and pseudophakic retinal detachment (psrd group).


This retrospective study statistically compares primary anatomical and functional outcomes in the prd group (44 cases) and psrd group (51 cases) patients, which underwent PPV+SB/PPV. Preoperative and intraoperative fundus findings in terms of vitreous base and retinal breaks were compared statistically.

Effectiveness / Safety:

The Psrd group had multiple breaks (65%), a large vitreous base (47%), irregular posterior edge of the vitreous base and breaks in different meridians. The Prd group had a normal width vitreous base (95.5%), a regular posterior edge of the vitreous base and generally a single tear (63.6%). The differences were statistically significant. The differences in primary anatomical and functional results of PPV+SB and PPV were not significant in either group.

Take home message:

In this study PPV with vitreous base shaving was found to be as effective as PPV+SB based on primary anatomical and functional success in both groups.
In our opinion, further studies including larger number of cases are necessary to determine primary anatomical success of PPV and PPV+SB, the properties of the vitreous base and the relation between retinal tears in the prd and psrd groups.
