Tenon's Capsule Graft as a Sealant in Pediatric Retinal Detachment.

PURPOSE: To describe a surgical technique utilizing an autologous tenon's capsule graft, in four cases of complex retinal detachments associated with infantile high myopic macular holes (MH), Morning Glory Syndrome (MGS), and an optic disc pit maculopathy.

METHODS

Tenon's capsule was exposed following conjunctival incision, separated from the episcleral tissue, and excised to appropriate sizes. The tenon grafts were then inserted through a sclerotomy and positioned over the MH (2 eyes) and the excavation of the morning glory disc (1 eye), and implanted over the optic disc pit (1 eye) under a small PFCL buble. Silicone oil tamponade was used in all cases.

RESULTS

All cases achieved successful retinal reattachment and demonstrated stable integration of the Tenon's capsule grafts over a follow-up of more than 6 months, with no signs of infection or inflammation. Silicone oil was removed in MH cases and the grafts remained stable.

CONCLUSION

Tenon's capsule transplantation emerges as a promising alternative sealing material in pediatric vitreoretinal surgery, offering potential advantages in terms of availability, stability, and efficacy. Further validation through larger studies across diverse retinal pathologies is warranted to ascertain its broader applicability and impact on visual function.
