@article {1511503, title = {Impact of contact versus non-contact wide-angle viewing systems on outcomes of primary retinal detachment repair (PRO study report number 5)}, journal = {Br J Ophthalmol}, volume = {105}, number = {3}, year = {2021}, month = {2021 Mar}, pages = {410-413}, 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.}, issn = {1468-2079}, doi = {10.1136/bjophthalmol-2020-315948}, author = {Tieger, Marisa G and Rodriguez, Marianeli and Wang, Jay C and Obeid, Anthony and Ryan, Claire and Gao, Xinxiao and Kakulavarapu, Srividya and Mardis, Patrick J and Madhava, Malika L and Maloney, Sean M and Adika, Adam Z and Peddada, Krishi V and Sioufi, Kareem and Stefater, James A and Forbes, Nora J and Capone, Antonio and Emerson, Geoffrey G and Joseph, Daniel P and Regillo, Carl and Hsu, Jason and Gupta, Omesh and Eliott, Dean and Ryan, Edwin H and Yonekawa, Yoshihiro} }
