Abstract Background Vitreous biopsy is a common technique used to guide management of acute endophthalmitis and help differentiate between infectious and inflammatory conditions.Currently, in-clinic vitreous biopsy is performed with a 25-gauge needle, without the ability to cut vitreous, potentially leading to reduced diagnostic yield.Recent work demonstrated the ability to perform vitreous biopsy with an off-the-shelf vitreous cutter.However, this was limited by complexity of assembly.Here, a technique using a single peel pack vitrectomy cutter is demonstrated for in-clinic vitreous biopsy.

Methods A 25-gauge vitreous cutter is opened from a peel pack.The duospiritalis.com drive line is identified, cut to length, and attached to a 10 mL syringe.A 1 mL syringe is attached to the aspiration line.After a trocar is used to place a cannula in the pars plana, the vitreous cutter is introduced into the eye.Cutting is performed by an assistant actuating the 10 mL syringe while read more the surgeon aspirates from the 1 mL syringe.

After sample is collected, antimicrobials are injected if required and the cannula is removed.Results A peel pack technique simplifies assembly for an in-clinic vitreous biopsy using a manually actuated cutter.Conclusion We present a novel, improved, and simplified technique for vitreous tap using a vitreous cutter provided in a single peel pack, actuated by a single syringe with minimal assembly prior to use.This technique may be more accessible for clinicians than prior techniques and does not require a surgical console.
