The Role of Proportional Reflux During Pars Plana Vitrectomy for Tractional Retinal Detachments.

BACKGROUND AND

OBJECTIVE

To discuss the role of proportional reflux hydrodissection (PRH) during pars plana vitrectomy (PPV) in eyes with diabetic tractional retinal detachment (TRD).

PATIENTS AND

METHODS

In this retrospective study, records of patients with diabetic TRD involving the fovea undergoing PPV with the help of PRH between January 2015 to March 2017 were noted. PRH relies on the Constellation system's proportional reflux feature. The mean age, gender, and pre- and postoperative best-corrected visual acuity (BCVA) were noted. Minimum follow-up period of 3 months was ascertained.

RESULTS

Thirty-three patients were included. Preoperative and postoperative BCVA were 1.80 logMAR units and 1.20 logMAR units, respectively. Fifteen patients also received preoperative intravitreal ranibizumab. Twelve percent needed the help of a second instrument. Thirty-three percent developed intraoperative iatrogenic breaks, and 39.39% needed oil/gas tamponade. All patients had successful reattachments at 3-month follow-up.

CONCLUSIONS

PRH is simple, cost-effective, surgeon-friendly, and highly controlled technique helpful in managing diabetic TRD. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:113-115.].
