Transconjunctival Sutureless 23-gauge Vitrectomy for Diabetic Retinopathy. Review

This paper reviews the current experience and trends in 23-gauge transconjunctival sutureless vitrectomy for diabetic retinopathy in those patients that need a surgical intervention for either vitreous hemorrhage, fibrovascular proliferation with traction retinal detachment affecting or threatening the macula, traction-rhegmatogenous retinal detachment, or refractory macular edema with taut posterior hyaloid. Since the instruments in 23-gauge vitrectomy are less flexible and perform in a more similar way to 20-gauge instruments, the vitrectomy is more thorough and for more complex manoeuvres can be done. The 23-gauge transconjuntival sutureless vitrectomy avoids some of the shortcomings of the 25- gauge systems.
