All patients had an axial length ≥ 26 mm. Main outcome measures were retinal re-attachment and macular hole closure after silicone oil removal, improvement of best-corrected visual acuity (BCVA), and complications secondary to surgery. Chi square/Fisher’s exact test was used to analyze categorical variables, while One-way ANOVA/Kruskal–Wallis test was used to compare variables across the closure type and complications. Correlations between numerical variables were tested using Spearman correlation. Kaplan–Meier method was used to estimate the event-free survival. P value is significant at 0.05.Results: The study included 26 eyes of 26 patients. Retinal re-attachment rate after primary and secondary surgeries was 88.4% and 100%, respectively. W-type macular hole closure occurred in 58% of eyes. Vision improved in 58% of eyes. Mean final BCVA was 0.05 decimal units, p = 0.004. Cataract and glaucoma developed in 42% and 15% of

Surgeries were performed between May 2011 and November 2016. Patients were followed up for at least 18 months after last intervention. The included eyes were categorized into two groups. Group A (vitrectomy with additional encircling band) included 72 eyes of 72 children; 58 boys and 14 girls. Group B (vitrectomy without encircling band) included 67 eyes of 67 children; 58 boys and 9 girls. In group A, the mean age was 9.21± 3.24. Attached retina was achieved in 61% (44 out of 72 eyes), of which 34 eyes remained attached after silicon oil removal, and 10 eyes remained attached under silicon oil tamponade. Recurrent RD under oil was present in 28 eyes (38.9%). In group B, the mean age was 11.06± 3.64. Attached retina was present in 61.2% (41 out of 67 eyes), of which 30 eyes remained attached after oil removal, and 11 eyes remained attached under silicon oil tamponade. Recurrent RD was present in 26 eyes (38.8%). In group A, the
