Purpose:To determine whether triamcinolone acetonide (TA)staining facilitates posterior hyaloid removal in patients undergoing pars plana vitrectomy (PPV) for retinal disease.Methods: A triamcinolone acetonide(TA)-assisted vitrectomy was performed on patients with the following disease: proliferative diabetic retionpathy(5eyes), central retinal vein occlusion(5eyes), macuar hole (3eyes), and epiretinal membrane(2eyes). Eyes without apparent preoperative posterior vitreous detachment were enrolled in this study. After a core PPV, TA aqueous suspension (40 mg/ml) was injected into the mid vitreous cavity to visualize the posterior hyaloid, thus allowing a complete posterior hyaloid separation and removal. The visual acuity, intraocular pressure (IOP), tamponade, corneal pathology, after-cataract, vitreous hemorrhage, and necessity for reoperation were thereafter examined for at least 3 months after surgery.Results: In all patients, the vitreous body was clearly seen by means of triamcinolone during surgery, a
