Anatomic success rates of endoscopy-assisted pars plana vitrectomy (EAPPV) for tractional retinal detachment repair (TRD) are higher compared with reported rates for operating microscope PPV (OMPPV), according to research presented at the American Society of Retina Specialists 40th Annual Meeting, held in New York, July 13-16, 2022.
Proliferative vitreoretinopathy (PVR) is the most frequent cause of redetachment after TRD. The reported success rates for OMPPV TRD repair range from 45% to 85%.
The presenters shared outcomes of 55 patients (mean age: 56.3±15.9 years, 34 men, 21 women) who underwent EAPPV for TRD repair between August 2017 and August 2021. All patients had at least 1 month of follow-up after surgery. The study excluded pregnant women and individuals younger than 18 years.
All patients had 23 G endoscopy via 23 G trocar cannulas. Intraocular tamponade was used with silicon oil in 41 patients (74.5%) and gas in 14 patients (5 had air [9.1%], 5 had SF6 [9.1%], 4 had C3F8 [7.3%]).
After 1 month, the redetachment rate was 5.45% (3 patients with silicon oil tamponade). Redetachment rate was 9.10% in patients who were followed for at least 1 year (5 patients with silicone oil tamponade), according to the report.
“EAPPV facilitated anterior PVR visualization and dissection,” according to the researchers. “Anatomic success rates of EAPPV for TRD were high relative to reported rates for OMPPV.”
Limitations of the study included its retrospective design and the relatively small sample size of patients.
