Abstract

PURPOSE: To describe the clinical experience and safety profile of a combination of 23-gauge and 20-gauge transconjunctival sutureless vitrectomy (TSV)
METHODS
Thirty-seven eyes of thirty-seven consecutive patients who underwent 23-gauge combined with 20-gauge transconjunctival vitrectomy surgery by a single surgeon from August 2006 through December 2006 were reviewed retrospectively for surgical indications, wound problems, and postoperative complications.
RESULTS
Thirty-seven eyes, including eyes with proliferative diabetic retinopathy (n=24), macular hole (n=3), epiretinal membrane (n=3), vitreous hemorrhage due to branch retinal vein occlusion and choroidal neovascular membrane (n=3), vitreous opacity secondary to uveitis (n=1), rhegmatogenous retinal detachment (n=1), and vitreoretinal traction syndrome (n=1), underwent operation. Seven eyes at 23-gauge sclerotomy sites and 15 eyes at 20-gauge sclerotomy sites had subconjunctival hemorrhage. Three eyes required sutures at 20-gauge sclerotomy sites intraoperatively due to wound leakage. One wound hemorrhage occurred at a 23-guage sclerotomy site. Vitreous hemorrhage (4 eyes), hyphema (2 eyes), and vitreous hemorrhage with hyphema (1 eye) occurred postoperatively. Postoperative hypotony, retinal detachment, and other complications did not occur.
CONCLUSIONS
A combination of 23-gauge and 20-gauge transconjunctival sutureless vitrectomy which was created by modifying transconjunctival sutureless vitrectomy systems published previously guarded against sclerotomy wounds and a variety of vitreoretinal surgical indications.

Figure

  • Figure 1. (A) Standard position of two 23-guage microcannulas and 20-guage self-sealing sclerotomy in the left eye (surgeon’s view). Note the tunnel-shaped opening of cannulas and a special pressure plate for easy insertion of the vitreoretinal instruments.(B) Pressure plate which is sutured at 20-gauge self-sealing sclerotomy to prevent operative chemosis. The size of internal opening was 2 mm×1.5 mm for movement of 20-gauge instruments. 4 notches were suture sites for fixation of plate on the conjunctiva and sclera
