Purpose:
To evaluate the incidence of persistent diplopia in primary position after encircling band procedures with pars plana vitrectomy (PPV) and to report the outcomes.
Design:
Observational, retrospective study.
Participants:
One hundred sixteen patients who underwent successful rhegmatogenous retinal detachment (RRD) at our center from 2009 through 2014.
Methods:
We studied all patients with RRD who underwent successful PPV with an encircling band. Patients reporting diplopia more than 2 months after retinal surgery were identified and evaluated by our strabismus colleagues.
Main Outcome Measures:
Outcome measures included near and far deviation in prism diopters, degree of anisometropia, and visual acuity.
Results:
Six of 116 patients reported persistent diplopia in primary position (5.2%). The diplopia most often was related to vertical microdeviations from 3 to 5 prism diopters, and it was managed adequately with prisms. The deviation remained unchanged during the follow-up, except in 1 patient.
Conclusions:
Persistent diplopia associated to PPV with an encircling band has a low incidence and a small angle of deviation, and in our cases, it could be corrected successfully with prisms.

Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...
