Abstract

Purpose: To report the outcomes of laser therapy to barricade eccentric full-thickness macular hole with associated cystoid macular edema.

Methods: We report two patients who developed an eccentric full-thickness macular hole with persistent cystoid macular edema after pars plan vitrectomy with and without internal limiting membrane peel for epiretinal membrane and the results of argon laser therapy.

Results: Barricade argon laser therapy was applied concentric to the full-thickness macular hole. Associated cystoid macular edema was noted to resolve within 1 to 3 months of therapy in both cases.

Conclusion: Barricade laser therapy surrounding a macular hole can lead to resolution of associated cystoid macular edema. Pathogenic mechanisms to explain this favorable outcome are discussed.
