“…However, combining our data and the previous work by Dalma-Weiszhausz et al, 3 we believe that the IOP elevation during 25-gauge trocar placement is a potential issue that needs to be dealt with. Clearly, further research is needed in this field.…”

“…Acute IOP elevation in the setting of 25-gauge vitrectomy has only been reported in the recent work by Dalma-Weiszhausz et al, 3 and elevation .60 mmHg in human eyes and 50 mmHg in adult pig eyes had been found. An electronic applanation tonometer (Tono-Pen; Medtronic Solan, Jacksonville, FL) and a water height column were used to determine the IOP rise.…”

“…The increase has been generally overlooked until Dalma-Weiszhausz et al 3 reported it recently. Intraocular pressure has been demonstrated to elevate to .60 mmHg during trocar placement.…”

The advent of micro-incision vitrectomy surgery (MIVS) changed the approach, indications and complications of vitreoretinal surgeries forever. Since its introduction in 2002, MIVS has been gaining popularity amongst retinal surgeons for managing a wide variety of vitreoretinal disorders. MIVS allows for more efficient surgery, faster recovery time and better visual outcomes than 20G vitrectomy. The use of instrumentation having small diameters reduced trauma from conjunctival and scleral manipulation as well as post-operative inflammation and corneal astigmatism. Further refinement of techniques with the introduction of 27G for routine procedures increases the comfort for the patient and minimises the recovery time. In this review, we briefly summarise the journey of MIVS to its present status and discuss the various advances that have taken place to achieve better efficiency and results.

“…Additionally, placement of trocars requires the application of a compressive force to the globe to penetrate the sclera at an oblique angle (Wu et al, 2011). This force on the globe during insertion of the trocars has been shown to increase the IOP to as high as 63.7 mmHg (Dalma-Weiszhausz et al, 2008). The redesign of some trocar needles has partially reduced this problem.…”
