Performing 20-gauge two-port pars plana vitrectomy with slit lamp illumination was an effective technique for treating vitreoretinal pathologies without intraoperative complications, a study found.
The retrospective study included 195 consecutive eyes of 195 patients who underwent elective 20-gauge two-port PPV in conjunction with slit lamp illumination and a plano concave contact lens.
Patients’ postoperative visual acuity was measured at baseline and at months 1, 3 and 6. The researchers evaluated intraoperative and postoperative complication rates, as well as surgical time.
Mean overall visual acuity improved from 0.74 at baseline to 0.56 at 1 month, 0.48 at 3 months and 0.43 at 6 months (P < .0001 for all).
There were no intraoperative complications noted. Postoperative complications included retinal detachment in three cases, recurrence of epiretinal membrane in three eyes, incomplete macular hole closure in four eyes, phthisis in one eye and development of cataract formation in 25 eyes, according to the authors.
No cases of endophthalmitis were noted, and conversion to standard three-port PPV was avoided in all cases.
