We performed closed vitrectomy in 4 eyes of 4 babies with stage 5 retinopathy of prematurity. They were aged 18 to 23 weeks at the time of surgery born after 24 to 28 weeks of gestation. A 2.5 mm infusion cannula was inserted 1.5 mm posterior to the corneal scleral limbus so that it perforated the pars plicata of the ciliary body with its tip placed in the lens. We performed lensectomy and removed the retrolental fibrovascular tissue. After release of traction to the retina, viscoelastic material was injected into the vitreous to stretch the funnel-shaped retina. Iatrogenic retinal break was treated pneumatically, The retina was totally reattached in 1 eye and partially in 2. The present method of placing the irrigation port was useful and had the following advantages: lesser risk of damage to the peripheral retina and to the corneal endothelium, and larger surgical field.
