Background: Although widely accepted, pars plana vitrectomy is difficult to perform when patients have a large filtering bleb. We describe technical details of 25-gauge transcorneal vitrectomy and the clinical outcomes. Methods: We performed 25-gauge transcorneal vitrectomy on seven eyes of seven patients (female: male, 4:3; age, 39 to 77 years; mean, 66.1 years) between January 2005 and February 2007. Phacoemulsification via a corneal incision was followed by continuous curvilinear capsulorrhexis (CCC) of the posterior capsule. We used a notched contact lens to perform 25-gauge transcorneal vitrectomy. Results: Four patients with idiopathic ERM and three with secondary ERM were treated by 25-gauge vitrectomy. Postoperative visual acuity was good in most of them and the cell density of the corneal endothelium was maintained. Conclusion: These advantages of this procedure are that the conjunctiva and ocular surface can be completely maintained and vitreous incarceration can be avoided. Thus, 25-gauge vitrectomy might be particularly suitable for treating glaucoma with a filtering bleb. (158 words/200 words)
