Anatomical and visual results of transconjunctival sutureless vitrectomy using subconjunctival anesthesia performed on select patients taking anticoagulant and antiplatelet agents.

PURPOSE: The purpose of this study was to report the observed outcomes of anticoagulated patients undergoing transconjunctival sutureless vitrectomies using subconjunctival anesthesia without preoperative cessation of anticoagulation and antiplatelet (AC/AP) agents.

METHODS

A retrospective chart review was performed on patients taking AC/AP agents who were undergoing transconjunctival sutureless vitrectomies with subconjunctival anesthesia between January 2007 and June 2009. Intra- and postoperative complications (such as massive hemorrhage), anatomical results, satisfactory analgesia (informed by patients and recorded by surgeon), anatomical results, and visual acuity were documented.

RESULTS

Sixty-three surgeries were performed on 56 eyes of 52 patients. Thirty-two patients were taking aspirin and clopidogrel, 18 were taking warfarin, 5 were taking clopidogrel, 3 were taking aspirin and warfarin, 2 were taking acetylsalicylic acid and dipyridamole, and 1 was taking warfarin and clopidogrel. All patients had satisfactory analgesia. No intraoperative complications occurred. Seven eyes (13%) had postoperative vitreous hemorrhage. Overall, 79% of patients had improved postoperative visual acuity, 16% of patients had unchanged visual acuity, and 5% of patients had worse visual acuity at last follow-up visit.

CONCLUSION

Medical disease requiring systemic AC/AP therapy is often present in patients with vitreoretinal disease. Transconjunctival sutureless vitrectomies using subconjunctival anesthesia may be a safe and effective surgical option in select patients in whom cessation of AC/AP and/or delayed ophthalmic intervention is imprudent.
