While peeling an idopathic epiretinal membrane with a standard 23-gauge vitrectomy the Infusion port dislocated inadvertently and caused a massive uveal effusion.


By using an additional 20-gauge sclerotomy, it is possible to continue the vitrectomy, peeling the macular pucker and the inner limiting membrane in order to successfully complete the surgery. In this case, the 20-gauge sclerotomy serves as a drainage foramen as well as an additional access into the globe.


Due to the drainage effect of the 20-gauge Sclerotomy the uveal effusion resolves completely during the vitrectomy. The postoperative best-corrected visual acuity is 0.8.


Performing an additional 20 gauge Sclerotomy during a 23-gauge pars plana vitrectomy with uveal effusion is a reasonable and quick maneuver to drain suprachoroidal fluids. The surgery can be completed successfully without having found any adverse effects on the patient.
