Background: Several investigators tried to modify the technique of 20-gauge vitrectomy to
preserve the conjunctiva aiming to decrease surgical trauma and time.
Aim: To evaluate the efficacy and safety of 20-gauge trans-conjunctival vitrectomy for various
surgical indications.
Setting and Design: A retrospective review of an interventional case series.
Methods: This study included 59 eyes of 58 patients who underwent 20-gauge transconjunctival
vitrectomy for variable surgical indications using trocar system with suturing of the sclerotomies at
the end of surgery. Postoperative follow up records were reviewed and data collected included best
corrected visual acuity (BCVA), intraocular pressure, intraoperative and postoperative
complications for 6 months of follow up.
Results: The most common intraoperative complication was slippage of the cannula, occurred in 8
cases (14%); followed by trauma to the lens 4 cases (7%) and lastly retina incarcerated in the
cannula 2 cases (3.5%). The post-operative intraocular pressure (IOP) was high in 6 cases (10%).
The most common postoperative complication was inferior retinal detachment (RD) 12
