To evaluate ocular movement disorders after scleral buckling surgery for retinal detachment, factors affecting development of deviations, and their treatment.

In this observational case series, 206 eyes of 206 patients with the diagnosis of rhegmatogenous retinal detachment that underwent scleral buckling were assessed. Patients were followed from 6 months to 3 years after SBS in order to be evaluated for strabismus. Persistent diplopia and tropia more than 4 months was considered as persistent strabismus. Logistic regression analysis was used to evaluate factors associated with development of deviations.

From 206 cases, 56.8% were male and others were female. For 44.7% of patients, silicone band and tire (SBT) and for other 55.3%, sponge was used as the scleral buckle. Also, cryotherapy was performed in 81.6% cases during scleral buckling surgery. Among all patients, 3.39% cases including 4 males and 3 females exhibited ocular movement disorder which only in one patient SBT was inserted; while for others sponge buckle were used. For all 7 cases, cryotherapy was done. In analysis, no significant relation was found either between type of buckle (p-value=0.65) or the location of buckle (p-value= 0.56) and movement disorder. Finally, 5 patients were treated with different treatment methods such as removal of buckle, prism and botulinum toxin injection while others refused any treatment and only were followed.

Strabismus is a main complication after retinal detachment surgeries, especially SBS. After appropriate strabismus evaluations, treatment modalities such as surgery, botulinum toxin injection and prism prescription can be done.
