Plug the pit: a surgical technique for optic disc pit.

Purpose: To present a recently described surgical technique for the treatment of optic disc pit (ODP) and evaluate its outcomes.

Methods

A patient presented with refractory serous macular detachment and secondary full thickness macular hole associated with ODP, for which he had already undergone pars-plana vitrectomy with internal limiting membrane peeling and autologous serum application over the optic disc pit. A recently described surgical technique was carried out to treat this case. In this procedure, a silicone punctal plug was used to close the ODP. The macular hole was closed with a human amniotic membrane graft. Endotamponade was carried out with 1000cs silicone oil.

Results

Postoperatively, the serous macular detachment subsided and the punctal plug and amniotic membrane graft were in situ. Patient's visual acuity improved from counting fingers to 6/38 at one year postoperative.

Conclusion

This technique appears to be safe and effective in resolving long standing serous macular detachment associated with ODP, which was refractory to the conventional intervention. However, more cases and longer follow-ups are needed to affirm the safety and efficacy of this recently described procedure.
