Vitreous Hydro-dissection With a Flute Needle For Inducing Posterior Vitreous Detachment in Pediatric Retinopathies

Purpose: To present a novel intraoperative technique using a flute needle to induce posterior vitreous detachment in pediatric retinal cases. Methods: After 23-gauge pars plana vitrectomy in pediatric eyes with complex vitreoretinal disease, triamcinolone is applied for staining, and vitreous hydro-dissection is performed. A flute needle containing balanced salt solution is introduced to separate the thin residual posterior vitreous cortex from the retina near the vascular arcades. Gentle taps allow balanced salt solution to enter the vitreous crevice, with controlled oscillation facilitating separation. Posterior vitreous detachment is then induced, and the vitrector is used to lift and complete the detachment. Results: Vitreous hydro-dissection with a flute needle was effective in inducing posterior vitreous detachment in pediatric eyes with complex vitreoretinal disease. We report no intraoperative or postoperative complications. Conclusion: This adjuvant vitreous hydro-dissection technique facilitates posterior vitreous detachment induction and may reduce the associated risk of iatrogenic retinal damage.
