“…7,[14][15][16][17][18] Restrictive fibrosis has been observed during strabismus surgery following retinal cryopexy alone. 4,19,20 The differences seen in |dev| in the region of maximal deviation between our cohorts infers that of the several different mechanisms that may have a part in strabismus development; the presence of a buckle increases the deviation size in the extremes of gaze. This may be due to the tethering effect of buckling material on the vector forces of the muscles with which they are in direct contact, an effect that would be magnified in the more extremes of gaze.…”

“…Most studies are retrospective and concerned with strabismus following scleral buckling (SB) repair of retinal detachments (RD). The reported incidence of post-operative diplopia varies between 3-14% in retrospective, and 73% in prospective studies, [1][2][3][4][5][6][7] being highest during the immediate post-operative period, and often transient when the vision is good. 3 The strabismus is reported greater with multiple VR procedures, encircling buckling elements rather than sectoral explants, and increasing number of muscles the explant is in direct contact with.…”

Purpose We conducted a study to investigate: (1) deviations caused by retinal detachment (RD) repair; (2) correlation between visual acuity and the number of surgeries to deviation size; and (3) differences between deviations following scleral buckling (SB) and pars plana vitrectomy (PPV). Methods A retrospective analysis of patients with persistent binocular diplopia following RD repair. Magnitude of manifest deviation (|dev|) in the primary position (PP) and position of greatest deviation (maxDev) was calculated. LogMAR acuity and number of previous vitreoretinal procedures were correlated to |dev| in both PP and maxDev. Manifest |dev| were compared between SB and PPV groups. Results Twenty-five patients were identified. The median |dev| was 7 prism diopters (PD) in PP and 17 PD in maxDev. We found no association between number of surgeries or VA with |dev| in either the PP (r ¼ À0.18 and r ¼ 0.08) or maxDev (r ¼ À0.26 and r ¼ À0.05). Twelve patients underwent PPV: median |dev| in PP 6 PD and maxDev 9 PD. In the SB group: median |dev| in PP 8 PD and in maxDev 22 PD. |dev| in PP showed no significant differences between PPV and SB (U ¼ 63, P ¼ 0.41); however, |dev| in maxDev, showed that SB have significantly greater deviations (U ¼ 36.0, P ¼ 0.02). Conclusion We report the largest cohort of patients with symptomatic ocular motility defects following PPV. We show no association between VA or number of procedures to strabismus magnitude. Ocular deviations in maxDev are significantly greater after SB procedures.

Between 5% and 25% of patients may experience persistent diplopia after surgery for retinal detachment. The complexity of the presentation poses a distinct challenge to both the retinal and the strabismus surgeon. Careful evaluation to determine factors contributing to the strabismus and assessment of fusional capabilities are essential before treatment. A combination of the appropriate surgical approach with nonsurgical adjuncts such as prisms or botulinum toxin is often successful in relieving symptoms.

“…3,7,8,11,12 Restrictive fibrosis has been observed during strabismus surgery following retinal cryopexy without the use of any external exoplants. [13][14][15] These multiple etiologies all combine to result in strabismus often seen following vitreoretinal surgery. Of these, exoplant removal will only aid any strabismus caused by the mass effect.…”
