Abstract

Background/aims Vitrectomy to repair retinal detachment is often performed with either non-contact wide-angle viewing systems or wide-angle contact viewing systems. The purpose of this study is to assess whether the viewing system used is associated with any differences in surgical outcomes of vitrectomy for primary non-complex retinal detachment repair.

Methods This is a multicenter, interventional, retrospective, comparative study. Eyes that underwent non-complex primary retinal detachment repair by either pars plana vitrectomy (PPV) alone or in combination with scleral buckle/PPV in 2015 were evaluated. The viewing system at the time of the retinal detachment repair was identified and preoperative patient characteristics, intraoperative findings and postoperative outcomes were recorded.

Results A total of 2256 eyes were included in our analysis. Of those, 1893 surgeries used a non-contact viewing system, while 363 used a contact lens system. There was no statistically significant difference in single surgery anatomic success at 3 months (p=0.72), or final anatomic success (p=0.40). Average postoperative visual acuity for the contact-based cases was logMAR 0.345 (20/44 Snellen equivalent) compared with 0.475 (20/60 Snellen equivalent) for non-contact (p=0.001). After controlling for numerous confounding variables in multivariable analysis, viewing system choice was no longer statistically significant (p=0.097).

Conclusion There was no statistically significant difference in anatomic success achieved for primary retinal detachment repair when comparing non-contact viewing systems to contact lens systems. Postoperative visual acuity was better in the contact-based group but this was not statistically significant when confounding factors were controlled for.
