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, and complete removal of posterior hyaloid was facilitated and confirmed.Retina was attached in 14 of 15 eyes, and vision acuity was improved in 9 of 15 eyes.Two eyes showed transient postoperative IOP elevation, 2 eyes had after cataract formation and 1eye had cataract progression. Vitreous hemorrhage occurred in 1 eye. No eye had corneal pathology.Conclusion: Triamcinolone improved the visibility of the hyaloid and the safety of surgical procedures during PPV. No obvious adverse effect due to toxicity of TA accrued in TA-assisted PPV.展开更多

Identification of the pre-existing risk factors is of utmost importance so that precautionary modifications are done in the surgery to prevent this complication. Once it happens, timely realization and appropriate management can have excellent outcomes.展开更多
